ART. VII. A Practical Treatise on the Diseases of the Tatb; intended

as a Supplement to the Natural Hifory of those Parts. By John
Hunter, Surgeon Extraordinary to the King, and F.R.S. 4to.
Five Shillings fewed, or bound up with the first Part, one Guinea.
Johnson. 1778.
N the preceding part of this publieation, for our account of

which the reader may consult our 46th volume, page 603,
the Author confined himself to the anatomy and physiology of
the teeth : in the present he treats wholly of their diseases, or
irregularities, and of the consequences of them; discussing the
subject in ten chapters, in the first of which he treats of their
decay from rottenness, or denudation, of the swelling of their
fangs, of gum boils, excrescences from the gum, and abscesses in
the jaws. In the second chapter, the diseases of the alveolar
processes are discussed ; and in the third, those of the gums.
Nervous pains in the jaw form the subject of the fourth chapter ;
and in the four following the Author treats of the extraneous mat-
ter upon the teeth; of their irregularity; of irregularities between
them and the jaw; and of projections of the under jaw. In the
ninth chapter he creats pretty largely of the operations of draw-
ing and transplanting teeth : and in the tenth and laft, describes
the symptoms attending dentition, and the proper methods of
relief and cure.

In treating of the decay of a tooth, fuppofing the disease to be not so far advanced as to render the tooth useless; he advises that it should be extracted, and then immediately boiled, with a view not only to make it perfectly clean, but likewise to destroy any life* that may beinit. It is then to be replaced in the socket, where it can now suffer only from chemical or mechanical causes; as it is now dead, and incapable of being affected by any diseafe. This practice however is here said to be only sometimes followed with success; when it answers the same end as burning the nerve, but with much greater certainty.

Nervous pains in the jaws conftitute an excruciating and obstinate disease, which, in the Author's opinion, seems in reality to have no connection with the teeth, though they are generally fufpected to be the cause, or the seat of it. In a case of this kind the Author has known all the teeth of the affected fide drawn in succession without any advantage : on the contrary, the pain has sometimes become more diffused, and has at last attacked the corresponding side of the tongue. The disease is frequently periodical; but the bark often fails. The Author has seen cases of fome years ftanding, where hemlock has succeeded : but sometimes all attempts prove unsuccessful.

He adds however that sea-bathing has been of singular service in fome particular cases.

The transplanting of teeth is considered by the Author as the nicest of all operations relating to the teeth, and as requiring more chirurgical and physiological knowledge than any that comes under the care of the dentist. Though we cannot enter into the minutiæ of this difficult art, it may be of use to our readers in general to be acquainted with the following cire cumstances relating to the replacing of sound teeth, when they have been knocked out by accident; or, still more vexatiously, drawn by mistake.

The Author informs us that if a tooth be replaced at any time before its life is destroyed, it will re-unite with the cavity of the focket, and become as fast as ever ;, and that even the grinders may be thus treated with success, as their fangs will go as readily into their respective sockets as one fang would. Though no time should be lost in the performing of this operation, the trial is said to be adviseable even twenty-four hours after the accident, or as long as the socket will receive the tooth, which may be the case some days after the accident.

The Author relates one instance where a gentleman had the second Bicuspis loosened, and the first knocked out. He picked the latter up from the ground, and put it into his pocket. Some hours afterwards the Author washed it as clean as pollible in warm water, where he kept it some time, in order to soften it. • I then,' says he, replaced it, first having introduced a probe into the socket, to break down the coagulated blood which filled it. I then tied these two teeth to the first grinder, and the cuspidatus, with silk, which was kept on some days, and then removed. After a month they were as fast as any teeth in the head; and if it were not for the remembrance of the circumfances above related, the gentleman would not be sensible that his teeth had met with any accident. Four years have now paffed fince it happened.'

Mr. Hunter always supposes, in this treatise, that whenever the transplantation of a tooth has been attended with success, there has been a living union formed between the foreign tooth and the socket. The transplanted tooth is said to preferve a degree of transparency peculiar to a living tooth, and very different from the opaque chalky white of a dead tooth. He thinks too that the transplanted tooth is capable of becoming disealed; and even affirms that pain is sometimes felt in it. Be this as it may, the following curious experiment (which however only once succeeded with the Author) thews that when a living tooth has been transplanted into some part of a living animal, an actual communication of vessels is formed between

the

the tooth and the animal; or to use the Author's expression, that the tooth retains its life.

• I took,' says the Author, a found tooth from a person's head; then made a pretty deep wound with a lancet into the thick part of a cock's comb; and presfed the fang of the tooth into this wound, and fastened it with threads passed thro' other parts of the comb. The cock was killed some months after ; and I injected the head with a very minute injection: the comb was then taken off, and put into a weak acid, and the tooth be, ing softened by this means, I fit the comb and tooth into two halves, in the long direction of the tooth. I found the vessels of the tooth well injected, and also observed that the external surface of the tooth adhered every where to the comb by vessels, fimilar to the union of a tooth with the gum and fockets.' [Similar, though less singular, instances of an union formed between diffimilar parts of animal bodies, may be feen in our Re: view of the first part of this treatise above referred to, p. 604.]

In cases of difficult dentition the Author recommends the cutting the gums down to the tooth, as the only effectual method of cure; and relates some inftances of very singular symptoms such as contractions of the fingers and toes, Aux of matter from the urethra, &c.-inftantly removed either by that operation, or by the spontaneous cutting of a tooth.

Bury ART. VIII. A safe and easy Remedy proposed for the Stone and Gravel,

the Scurvy, &c. illustrated by Cases; together with an extemporaneous Method of impregnating Water, and other Liquids, with fixed Air, &c. By Nathaniel Hulme, M. D. &c. 460. Robinson, 1778.

N giving an account of a former publication of the Author's singular case there related; in which an immense number of calculous fragments, and a large quantity of a whitish mucous chalky substance, were discharged from the bladder of a patient, who had regularly for some time taken, by the Author's direction, an aqueous solution of 15 grains of fixed alcaline salt, and immediately afterwards swallowed a draught of water containing as much vitriolic acid as was known, a priori, to be fufficient to neutralize the alcali, and to expel from it all its fixed air.

In the first section of the present performance, the Author recapitulates the particulars of this case, and then proceeds to relate some other instances of the efficacy of this mode of adminiftering fixed air, in nephritic complaints, as observed by himself and others. In the second section he briefly treats of the efficacy of this medicine in the scurvy; and particularly relates the case of a person evidently labouring under the symptoms of the true sea scurvy, who was sensibly relieved after folRev. July, 1778.

lowing this course five or fix days, and cured of the complaint in a fortnight.

The advantages which have been derived, and which may be expected from the exhibition of fixed air, in this convenient and not very unpalatable mode of dispensing it, in cases of the gout, hectic fevers with consumption, putrid fevers, dysentery, and worms, form the subjects of the third, fourth, and fifth sections. Recommending the perusal of what the Author advances on these heads, to the medical reader, who may thence derive hints that may be of use in practice, we shall attend more particularly to the Author's last section; in which he describes an extemporaneous and fimple method of impregnating water and other liquors with fixed air, without the use of any particular apparatus, and by the mere mixture of two liquors.

These liquors are the solution of fixed alcali, and the water acidulated with vitriolic acid, described at the beginning of this article ; .but which, instead of being taken separately, are to be gradually and cautiously mixed with each other, so as to prevent the effervescence, or the disipation of the fixed air, as much as possible. The water, says the Author, tastes very brisk and acidulous, and sparkles when poured out of one glass into another.

- The more flowly and carefully the mixture of the alcaline and acid liquors is made, in this experiment, the more strongly will the water be charged with fixed air: for this reason it is best to let the second liquor run gradually down the side of the vefsel which is to contain them.' They will thus “ act filently on each other ; --and the fixed air of the alcali will be gently extricated from its basis, and immediately diffuse and incorporate itself into every adjacent particle of the water, till the whole Auid be fully saturated.'-The Author's usual mixture consists of 15 or 30 grains of salt of tartar diffolved in three ources of water, to which are added three ounces of water properly acidulated by means of the vitriolic acid.

The Author produces an experiment from which he infers that this mixture contains, or has imbibed, a greater quantity of fixed air than is contained in an equal quantity of the water impregnated with that fluid by means of the common glass apparatus. He forms this conclusion on Itis having found, in several comparative trials, that a greater quantity of fixed air is expelled, by means of heat, from a vial filled with the mixed alcaline and acid liquors, tban from another vial of the fame fize filled with the water impregnated by means of the common apparatus. But this is not a fair way of estimating the quantity of fixed air which water really imbibes in these two procefies.

In water impregnated in the common manner, the fixed air is actually combined with the water; whereas in the Author's ex
