الصفحة v - To give a stronger impulse and a more systematic direction to scientific inquiry, — to promote the intercourse of those who cultivate Science in different parts of the British Empire, with one another and with foreign philosophers, — to obtain a more general attention to the objects of Science, and a removal of any disadvantages of a public kind which impede its progress.
الصفحة 175 - ANALOGUE." — A part or organ in one animal which has the same function as another part or organ in a different animal.
الصفحة xvii - The undersigned, Envoy Extraordinary and Minister Plenipotentiary of the United States of America, had the honor duly to receive the note of the 15th of April, addressed to him by the Earl of Aberdeen, her Majesty's Principal Secretary of State for Foreign Affairs, in reply to the note of the undersigned of the 10th of August last, relative to the seizure of the American vessel the Washington, for having been found fishing within the limits of the Bay of Fundy. "The note of the undersigned of the...
الصفحة 269 - The heemal spine is much less constant as to its existence, and is subject to a much greater range of variety, when present, than is its vertical homotype above, which completes the neural arch. Long, slender, and ' spinous ' in the tail, the haemal spine is reduced to a short and thick bone, often flattened, in the thorax of mammals, a series of thirteen such modified spines forming the so-called 'sternum' in the two-toed sloth : the thoracic...
الصفحة 244 - He becomes the true discoverer who establishes the truth : and the sign of the proof is the general acceptance. Whoever, therefore, resumes the investigation of a neglected or repudiated doctrine, elicits its true demonstration, and discovers and explains the nature of the errors which have led to its tacit or declared rejection, may calmly and confidently await the acknowledgments of his rights in its discovery.
الصفحة 175 - A higher relation of homology is that in which a part or series of parts stands to the fundamental or general type, and its enunciation involves and implies a knowledge of the type on which a natural group of animals, the vertebrate for example, is constructed.
الصفحة 13 - These experiments show that when the difference of pressure in the first and second spaces is considerable, we can by no means suppose that the mean pressure at the orifice is equal to the pressure at a distance in the second space, nor even that there exists a contracted vein, at which we may suppose the pressure to be the same as at a distance.
الصفحة 104 - TABLE (continued). We see from these figures, that in the two years 1836 and 1837, Parliament passed 77 railway bills, of which 44 were for new lines, and that the capital thus authorized to be raised, amounted to more than 36 millions of money. The length of the lines then sanctioned amounted in the aggregate to nearly 1200 miles, and would call for the production of more than 500,000 tons of iron. The price of bar-iron, which in 1834 had been 6/. 10«.
الصفحة 175 - Homologous parts are always, indeed, analogous parts in one sense, inasmuch as, being repetitions of the same parts of the body, they bear in that respect the same relation to different animals. But homologous parts may be, and often are, also analogous parts in a fuller sense, viz. as performing the same functions : thus the fin or pectoral limb of a Porpoise is homologous with that of a Fish, inasmuch as it is composed of the same or answerable parts: and they are the analogues of each other, inasmuch...
الصفحة 241 - The cranium of the bird, which is composed in the adult of a single bone, is ossified from the same number of points as in the human embryo, without the possibility of a similar purpose being subserved thereby, in the extrication of the chick from the fractured egg-shell. The composite structure is repeated in the minute and prematurely-born embryo of the marsupial quadrupeds. Moreover, in the bird and marsupial, as in the human subject, the different points of ossification have the same relative...
