Binitrophenate of ethyl yields ethyl-nitrophenidine or nitrophanetidine (Co(H.NO,)NO,) by the action of sulphide of ammonium.

3. Phenate of amyl or phenamylol is formed on heating a mixture of phenate of potash and iodide of amyl in a sealed tube to a temperature of about 220° Fahr. It is a limpid, colourless oil, of agreeable odour. Its boiling point is about 436° Fahr. Nitric acid strongly attacks it, and the resulting compound yields amyl-nitrophenidine by the action of sulphide of ammonium.

Oxyphenic acid. (C12HO) Binoxide of phenyl; pyrocatechin; pyromorin tannic acid. This body is a product of the dry distillation of CATEC HU or of morintannic acid [TANNIC ACID.] The aqueous portion of the distillate is evaporated and set aside; the impure oxyphenic acid that deposits may be purified by recrystallisation from water, and finally by sublimation.

Oxyphenic acid crystallises in colourless rectangular prisms; it is very soluble in water or alcohol, but only slightly so in ether.

Unlike phenylsulphurous acid, however, it remains insoluble phenic acid, but the latter body does not yield it on being acted upon when the product referred to is diluted with water. by nitric acid. It is most readily obtained by acting upon asafoetida or extract of Brazil-wood with nitric acid; many other gum-resins also yield it under similar circumstances. The liquid product of the action of nitric acid upon these bodies is neutralised with carbonate of potash and crystals of styphnate of potash obtained by evaporation; these may be recrystallised from a small quantity of boiling water or the styphnic acid precipitated by nitric acid. Brazil-wood extract furnishes about 18 per cent. of styphnic acid. It may be obtained in large yellow prismatic crystals from solution in alcohol. It combines with acids to form crystalline salts, called styphnates or oxypicrates. They all explode violently when gently heated.

Sulphites of phenyl. Hydride of phenyl dissolves in fuming sulphuric acid, and forms phenylsulphurous or sulphobenzidic acid, C12H,SO, O но

It may be looked upon as the hydrated oxide of the radical sulphophenyl (C12H,S,O,). It forms extremely stable salts with acids called phenylsulphites, or sulphobenzidates. Nitric acid converts it into nitrophenylsulphurous or nitrosulphobenzidic acid, C12(H ̧NO1)S ̧O, O

Chloride of sulphophenyl (C12H,S,O,, Cl) is a colourless oil, of sp. gr. 1.378, and boiling point 489-2. It is formed on distilling phenylsulphite of soda with oxychloride of phosphorus. It is readily attacked by ammonia, with production of sulphophenylamide; and the latter, by the ordinary process of substitution, yields the following primary, secondary, and tertiary monamides, including a tertiary diamide:

Chloride of phenyl, or chlorhydrophenide (C12H,, Cl). A product of
the action of oxychloride of phosphorus on phenic acid. It is an
almost inodorous liquid, heavier than water.

Cyanide of phenyl (C,,H,Cy). Benzonitrile. Obtained by the distillation of dried benzoate of ammonia, as described under BENZOIC ACID. It a colourless oil, having an odour resembling that of bitter almond oil. It is soluble in alcohol or ether, but almost insoluble in water. Its sp. gr. is 1.0073; boiling point, 376° Fahr. Fuming nitric acid converts it into cyanide of nitrophenyl (C12(H.NO), Cy), or nitrobenzonitrile. PHENYL-PHTHALIMIDE. [NAPHTHALIC GROUP.]

PHENYL-SULPHURIC ACID (C,,H,S,O,). Sulphophenylic acid. A monobasic acid bearing the same relation to phenylic alcohol as sulphovinic acid sustains towards common or vinic alcohol. PHENYL-SULPHUROUS ACID (C12HS2O). Sulphobenzidic acid. A crystalline organic acid, obtained by gently heating benzole with its own volume of sulphurous acid. Its salts are monobasic and very stable.

PHIAL, LEYDEN. [ELECTRICITY.]

PHIGALIAN MARBLES, a series of sculptures in alto-rilievo, preserved in the British Museum, which are so called from having been discovered among the ruins of a temple at the ancient Bassa on Mount Cotylion, not far from the site of Phigalia. The subjects represented in them are the battle of the Centaurs and Lapithe, which occupies eleven slabs, and that of the Greeks and Amazons, in twelve slabs.

Fig. 1.

The height of each is 2 feet 1 inch, and the whole length about 100 feet. These rilievi formed a frieze round the interior of the cella, and were elevated about 22 feet from the ground.

Pausanias (viii. 41), describing the edifice from which these marbles were brought, says, "After that at Tegea, it may be considered the

| most beautiful of all the temples of the Peloponnesus." The roof of the building was of stone. It was dedicated to Apollo Epicurius, or the Deliverer, a title conferred upon him because he had delivered the Phigalians from a pestilence.

philosophy. Kant's main question proposed for solution in the criticism of reason was, 66 are metaphysics possible?" or, are synthetic judgments à priori possible?—judgments, or propositions, that is--the truth of which is not learned from experience, and which also are not merely analytical, or judgments in which the predicate barely unfolds the subject. Thus "all body is extended," is an analytical judgment: "all men are mortal," is synthetical indeed, but then it is à posteriori, being founded on experience: but, "every change must have a cause," is synthetical à priori, being universal and necessary, and founded in nothing but "pure understanding and reason." Now all such axioms, conceptions, and principles as are à priori, being enumerated, are regarded by those who make a distinction between positive and negative philosophy, as forming a negative philosophy, or as drawing the ground for a positive constructive system. Kant held out the expectation of such a system, as a superstructure to be erected by himself on the basis of the Kritik:' such a system of pure speculative reason I hope "to furnish myself, under the title, Metaphysic of Nature; which shall have far richer matter than this Kritik, though the latter was necessary, first to exhibit the sources and conditions of its possibility, and to cleanse and level a soil altogether overgrown with weeds." ("Kritik:' Vorrede.) Such a system would have been, in the German phrase, a positive philosophy: but the Transcendental Criticism professes only to examine and secure the foundation on which, the author says, every future metaphysic" must be built, and is, relatively to such supposed system, merely negative. The Positive Philosophy that Kant and the German metaphysicians only contemplated was at length propounded by M. August Comte, in his Cours de Philosophie Positive,' in 1830-1842, and his Discours sur l'Ensemble du Positivisme,' 1848. According to his system the human mind has passed through certain stages: the theological, in which supernatural agencies are necessary; the metaphysical, in which super-coloured, and part crimson; and he is for the most part very like to natural aids are dismissed, and their place supplied by abstract ideas. These stages he deems incorrect, and holds that the mind now arrives at the last and highest stage the positive, in which it grasps all that can be known with certainty, such as scientific truths, and holds that in other more complex subjects, such as Biology and Sociology (social science), definite laws prevail which may be ultimately discovered by strict observation and deduction, and that nothing is to be believed that cannot be proved.

PHOENIX (Povic), one of the most renowned of the fabulous monsters of antiquity, defined by the Arabians to be a "creature whose name is known, its body unknown." (Richardson's 'Arabic and Persian Dict.') The earliest author who mentions it is Hesiod (ap Plut., ' De Defectu Orac.,' cap. 11; and ap. Plin., 'Hist. Nat.,' lib. vii. cap. 49), who merely says that it lives nine times as long as a crow The first detailed description and history that we meet with is in Herodotus, whose words on that account deserve to be quoted at length. "There is also," says he, in his account of Egypt (lib. ii., cap. 73)," another sacred bird, the name of which is the phoenix; I have not myself seen it except in a picture, for it seldom visits them, only (as the people of Heliopolis say) every five hundred years. And they say that he only comes when his sire dies. And he is, if he is like his picture, of size and shape as follows: part of his plumage is goldthe eagle in outline and bulk. And this bird, they say, devises as follows, but they say what is to me beyond belief: that setting out from Arabia, he brings his sire to the temple of the sun; that he covers him with myrrh, and buries him in the temple of the sun; and that he covers him thus: first he forms an egg of myrrh as large as he is able to bear, and afterwards tries whether he can carry it; and when he has made the trial, upon this he hollows out the egg, and puts his sire into it, and covers with other myrrh that part of the egg where he had made the hole and put in his sire; and when his sire lies inside, the weight [of the egg] is the same [as it was before it was hollowed out], and having covered him up, he conveys him to Egypt into the temple of the sun. Such are the things which they say this bird. performs." Such is the story as told in Herodotus, and it is substantially the same as what was afterwards, though with various embellishments, repeated and believed for more than a thousand years. It would be tedious and useless to quote the words of each author who forms the link in the chain: it will be sufficient to mention that between the times of Herodotus and Tacitus, the fable of the 'Phoenix' is told more or less fully and circumstantially by numerous classical writers. Of these writers perhaps the only passage curious enough to be particularly noticed is that in Lampridius, who tells us that Heliogabalus promised his guests a phoenix for supper; he was, however, obliged to be content with a dish of the tongues of phoenicopters (or flamingoes).

PHILTER (pixTpov, philtrum), was a potion given among the Greeks and Romans to excite love. It is doubtful of what these potions were composed, but their operation was violent and dangerous, often depriving those who drank them of their reason. (Ovid,' Ar. Amat.,' ii. 106.) Lucretius is said to have died from drinking a potion of this kind; and the madness of Caligula is attributed by some to a similar potion, which was given him by his wife Casonia. (Suet., 'Cal.,' 50; Juv., vi. 615, 616.) The most powerful love potions were prepared by the Thessalians, whence Juvenal speaks (vi. 610) of Thessala philtra.

PHLOGISTICATED AIR. An obsolete name for NITROGEN. PHLOGISTON, an hypothetical substance, by supposing the existence of which Stahl [STAHL, in BIOG. DIV.] explained the phenomena of combustion. He imagined that by combination with phlogiston a body was rendered combustible, and that its disengagement occasioned combustion, and after its evolution there remained either an acid or an earth: thus sulphur was by this theory supposed to be composed of phlogiston and sulphuric acid; and lead, of the calx of lead and phlogiston, &c.

At this period, however, oxygen had not been discovered, and although Jean Rey had shown that metals by burning increased in weight, and Hooke and Mayow had attributed combustion to the presence of the air in which it occurs, yet the doctrine proposed by Stahl maintained its ground for about half a century. Soon after the discovery of oxygen gas by Dr. Priestley, the experiments which others had made on the calcination of the metals were repeated with great accuracy by Lavoisier; the consequence was, that the phlogistic theory gave way to the antiphlogistic; for the combustion, which had been attributed to the extrication of phlogiston, was known in all common cases to be derived from the absorption of oxygen, and this explained the increase of weight which bodies acquired by combustion, whereas on the phlogistic theory they ought to have suffered a diminution by the process.

PHLORIZIN (CH20+4 Aq.) Phloridzin, a peculiar vegetable matter which exists in the bark of the trunk and roots of the apple, pear, cherry, and plum trees. According to Stass it is most readily obtained, and in large quantity, by treating either the fresh or dried roots of the apple-tree with weak alcohol at the temperature of about 150° Fahr. When the digestion has been continued for some hours, the clear solution is to be poured off, and the alcohol distilled; the residual liquor on cooling, deposits phlorizin, which is to be rendered colourless by animal charcoal.

Phlorizin, when deposited from a saturated solution, has the form of silky tufts; but when obtained by the slow cooling of a dilute solution, it is in long flat brilliant needles. The taste of phlorizin is rather

But it is not only in heathen authors that this fable is to be found; it is mentioned and believed by the Jewish rabbinical writers, and by the early fathers of the Christian church. The very words of several of these writers may be seen in Bochart (loco cit.); but the only rabbinical addition to the story worth noticing is preserved by Rabbi Osaia in his Berescith Rabba,' cap. 19 (ap. Bochart loco cit.), who says that the reason why the phoenix lives so long, and is in a manner exempt from death, is because it was the only animal that did not eat of the forbidden fruit in Paradise. A somewhat similar bird seems to have been known to the Arabians under the name of Anka. Mr. Lane, in the notes to his translation of the Tales of a Thousand and One Nights' (ch. 20, note 22), tells us, on the authority of Kaswini, that the anka is the greatest of birds; that it carries off the elephant as a kite carries off the mouse; that, in consequence of its carrying off a bride, God, at the prayer of a prophet named Handhalah, banished it to an island in the circumambient ocean, unvisited by men, under the equinoctial line; that it lives one thousand and seven hundred years; and that when the young anka has grown up, if it be a female, the old female bird burns herself; and if a male, the old male bird

does so.

Many of the early fathers believed the story so firmly that they did not hesitate to bring it forward as a proof of the resurrection; and that, not as an argumentum ad hominem, when disputing with heathens, but seriously, and in writings addressed to converts to Christianity. St. Clement is the first who uses this argument (loco cit.), in which he is followed by St. Cyril and Tertullian (locis cit.), and Epiphanius (Ancor., sec. 84, p. 89). The passage in St. Cyril (which also contains two or three additional embellishments) will serve as a specimen. "God knew men's unbelief," says he (in Mr. Church's translation, Oxford, 1838), "and provided for this purpose a bird called a phoenix. This bird, as Clement writes, and as many more relate, the only one of its race, going to the land of the Egyptians at revolutions of five hundred years, shows forth the resurrection; and

this, not in desert places, lest the mystery which comes to pass should remain unknown, but in a notable city, that men might even handle what they disbelieve. For it makes itself a nest of frankincense and myrrh and other spices; and entering into this when its years are fulfilled, it evidently dies and moulders away. Then from the mouldering flesh of the dead a worm springs, and this worm, when grown large, is tranformed into a bird; and do not disbelieve this, for thou seest the offspring of bees also fashioned thus out of worms, and from eggs which are most moist thou hast seen the wings and bones and sinews of birds issue. Afterwards this phoenix, becoming fledged and a perfect phoenix, as was the former one, soars up into the air such as it had died, showing forth to men a most evident resurrection from the dead. The phoenix indeed is a wondrous bird, yet is irrational, nor sings psalms to God; it flies abroad through the sky, but it knows not the only-begotten Son of God. Is then a resurrection from the dead given unto this irrational creature, which knows not its maker; and to us, who ascribe glory to God and keep his commandments, shall there no resurrection be granted?"

Origen seems to doubt its truth (‘Cont. Cels.,' lib. iv., cap. 98, p. 229), and Photius blames St. Clement for his credulity in mentioning it (Biblioth.,' cod. 126, p. 305); but these two are (so far as the writer is aware) the only two of the ancient authors who did not believe it. This, however, ought not to lessen the authority of the fathers on other matters, nor should it be made a subject of reproach against them that "they were not proficients in a branch of knowledge which has been a peculiar study of modern times." (See Mr. Newman's preface to Mr. Church's Translation of St. Cyril,' Oxf., 1838.)

It would be almost impossible to enumerate all the more modern authors who, during the middle ages, expressed their belief in the existence of the phoenix, for the list would include almost all the writers on natural history, besides a great number of others. Perhaps the most curious circumstance relating to it is what is told us by Camden ('Britannia,' p. 783, ed. Lond., 1607), namely, that Pope Clement VIII. sent, in 1599, to Lord Tyrone, the chieftain of the Irish rebels, a phoenix's feather. This was mentioned in his work only eight years after the event took place, but we are not informed how the pope procured the feather, or what had become of it at the time when Camden wrote. Sir Thomas Browne, in his 'Vulgar Errors' (of which the first edition was published in 1646), thinks it necessary to state at some length his reasons for disbelieving the existence of the phoenix (book iii. ch. 12); and in 1552 he was attacked for this and other pieces of incredulity by Alexander Ross, in a work entitled 'Arcana Microcosmi, or the Hid Secrets of Man's Body discovered,' &c. With respect to the phoenix, the writer is not surprised at its seldom making its appearance, its instinct teaching it to keep out of the way of the tyrant of the creation-man; "for had Heliogabalus, that Roman glutton, met with him, he had devoured him, though there were no more in the world!" (Arca. Micr.,' p. 202.) Alexander Ross, who was really a person of some sense and learning, was probably one of the last believers in the phoenix, which is now given up entirely to the poets; indeed, since the appearance of the 'Rejected Addresses, almost abandoned even by them.

PHOENIX, a southern constellation of Bayer, which may be best described as close to (but farther from the south pole than) the bright star in Eridanus (Achernar). Its principal stars are as follows:

When phosphorus is exposed to the air it undergoes slow combustion, and emits a feeble light which is visible in the dark. Certain mineral substances emit a phosphorescent light when gently hea ted, such as phosphorite and chlorophane. The light however soon ceases and cannot be renewed until the body has been exposed to the sun, or to the electric flash produced by discharging a Leyden jar. Several kinds of sea fish become luminous soon after death, and the waters of the ocean frequently appear luminous from the presence of luminous animalcule this, however, is a subject which belongs to our NATURAL HISTORY DIVISION-LUMINOSITY OF ORGANIC BEINGS.

PHOSPHORIC ACID. [PHOSPHORUS.]

mineral acids in not affecting so strongly the digestive organs, on which account it may be persevered in for a longer time. It is peculiarly suited to disordered states of the mucous surfaces, and also to states of debility, characterised by softening of the bones and a phosphatic condition of the urine. In this latter state it is often more efficacious when combined with iron, in the form of a phosphate of that metal; or better, the pyrophosphate. The same combination is of great utility in most cases of diabetes. In passive hemorrhages, phosphoric acid, properly diluted, quickly arrests the bleeding, as it coagulates the blood. This property is possessed in a stronger degree by the undiluted acid; and hence if injected into a vein, causes death. A poisonous dose of the strong acid may be counteracted by chalk, or carbonate of soda.

PHOSPHOROUS ACID. [PHOSPHORUS.]

PHOSPHOVINIC ACID, Ethyl-phosphoric acid. [ETHYL.]

PHOSPHORUS. This elementary, solid, non-metallic body was discovered in 1669, by Brandt, an alchemist of Hamburg; he kept the mode of preparation for a long time secret, but as he could not conceal the fact of its being obtained from urine, Kunkel tried to procure it from the same source, and he succeeded in the attempt.

It will not be requisite to describe the original mode of preparing this very peculiar substance; therefore we shall only give an outline of the method at present employed. It has been shown that animal bone [BONE, in NAT. HIST. Div.] contains a large quantity of phosphoric acid combined with lime, forming a phosphate of that earth. It was first proposed by Scheele to obtain phosphorus from bones. For this purpose the bones are ignited or calcined in contact with air till they become white; when this happens it is a proof that the charcoal derived from the decomposition of the animal matter is entirely burnt off. In this state they consist of phosphate of lime mixed with little else than a small portion of carbonate of lime. After being reduced to a fine powder, they are mixed with sufficient water to form a thin paste, and digested for a day or two with two-thirds their weight of sulphuric acid. In this case sulphate of lime is formed, and the greater part of it remains insoluble, and a superphosphate of lime remains in solution; this is to be evaporated, and the precipitate formed being separated, the clear fluid, which is chiefly phosphoric acid, is to be evaporated nearly to dryness, and mixed with about a fourth of its weight of powdered charcoal; this mixture is to be strongly heated in an earthen retort, the beak of which is immersed in water; by the action of the heat the phosphoric acid yields oxygen to the carbon, and the results are carbonic acid or oxide, which is evolved in the gaseous state, and the vapour of phosphorus, which is condensed by passing into water. The crude phosphorus thus obtained is mixed with wet sand and purified by redistillation from a large cast-iron retort, the neck of which just dips below the surface of water contained in a flat earthenware pan. The phosphorus is from time to time removed by an iron ladle and cast into sticks by fusing under warm water in a vessel that has a long glass tube attached to its lower part by a stopcock. The tube is surrounded by cold water contained in a tub, and at first its end is closed by a cork. On opening the tap the melted phosphorus flows into the glass tube, and when it has solidified, the cork is carefully withdrawn, and with it the rod of phosphorus, fresh liquid phosphorus continuing to flow in. By this means the whole of the phosphorus may be drawn out in one continuous stick of any required diameter, and coiled round in the tub or cut into pieces with scissors while still under water.

Phosphorus is solid, translucent, and nearly colourless; it is so soft that it may be indented by the nail, and it is very readily cut. When heated to 111.5° Fahr. it fuses, and at 550° is converted into vapour; it has a peculiar smell when exposed to the air, but this is probably derived from the action of the oxygen of the air upon it. Neither water nor alcohol dissolves phosphorus, but it is slightly dissolved by ether and by oils. It emits light when exposed to the air in the dark, and hence its name (from pws, light, and pépew, to carry). It is extremely inflammable, and has been known to take fire spontaneously in the atmosphere when the temperature was not above 60° Fahr. Its specific gravity is about 1.83. Phosphorus is also soluble by the aid of heat in naphtha, bisulphide of carbon, and dichloride of sulphur; on cooling from solution in the last-mentioned it has been obtained in dodecahedral crystals, and by mere fusion and slow cooling of a larger quantity, it has been procured in octohedral crystals.

Phosphorus may be granulated by fusing under alcohol, or in water containing a little urea, and well agitating till cold.

Amorphous, or red Phosphorus is an allotropic variety that has long been known to chemists, but has been extensively manufactured only since the year 1848. It is most easily made by keeping ordinary phosphorus for several days at a temperature of 450° or 460° Fahr. It forms a red or purple friable amorphous mass. Its specific gravity melting point and igniting point are higher than ordinary phosphorus. It is insoluble in bisulphide of carbon, is neither dangerously inflammable nor poisonous, and does not communicate to the workpeople engaged in handling it, that painful disease of the jaws that ordinary use in the manufacture of lucifer matches, and it was at one time hoped that it would quite supersede the white variety: unfortunately however, it gradually attracts oxygen from the air and the phosphorous
