Síða 346 - History warns us, however, that it is the customary fate of new truths to begin as heresies and to end as superstitions ; and, as matters now stand, it is hardly rash to anticipate that, in another twenty years, the new generation, educated under the influences of the present day, will be in danger of accepting the main doctrines of the Origin of Species...
Síða 376 - Their principal ornament is the bone which they thrust through the cartilage that divides the nostrils from each other : What perversion of taste could make them think this a decoration, or what could prompt them, before they had worn it or seen it worn, to suffer the pain and inconvenience that must of necessity attend it, is perhaps beyond the power of human sagacity to determine : As this bone is as thick as a man's finger, and between five and six inches long, it reaches quite across the face,...
Síða 351 - On this doctrine of the extermination of an infinitude of connecting links between the living and extinct inhabitants of the world, and at each successive period between the extinct and still older species, why is not every geological formation charged with such links ? Why does not every collection of fossil remains afford plain evidence of the gradation and mutation of the forms of life ? We meet with no such evidence, and this is the most obvious and plausible of the many objections which may...
Síða 380 - The traveller who has been the eye-witness of such customs may well add, "Even amongst these uncultured children of nature, human pride crops up amongst the fetters of fashion, which, indeed, are fetters in the worst sense of the word ; for fashion in the distant wilds of Africa tortures and harasses poor humanity as much as in the great prison of civilization.
Síða 349 - Amphioxus and of the T-unicata prove, beyond a doubt, that the differences which were supposed to constitute a barrier between the two are non-existent. There is no longer any difficulty in understanding how the vertebrate type may have arisen from the invertebrate, though the full proof of the manner in which the transition was actually effected may still be lacking. Again, in 1859, there appeared to be a no less sharp separation between the two great groups of flowering and flowerless plants. It...
Síða 386 - But, on the contrary, when the thongs were loosened, and the pads removed, I have noticed them cry until they were replaced. From the apparent dulness of the children whilst under the pressure, I should imagine that a state of torpor or insensibility is induced, and that the return to consciousness occasioned by its removal, must be naturally followed by the sense of pain.
Síða 625 - ... in the dark, I have found out that this is by no means the case, but that a kaleidoscopic change of patterns and forms is continually going on, but they are too fugitive and elaborate for me to draw with any approach to truth.
Síða 386 - It might be supposed," observes Mr. Kane, who had large opportunities of watching the process, " that the operation would be attended with great suffering, but I never heard the infants crying or moaning, although I have seen their eyes seemingly starting out of the sockets from the great pressure ; but, on the contrary, when the thongs were loosened and the pads removed, I have noticed them cry until they were replaced. From the apparent...
Síða 113 - ... no preternatural qualities, and differs from real living animals only in extreme smallness and agility. He can at pleasure stop, or strike, or push, or pull any single atom of matter, and so moderate its natural course of motion. Endowed ideally with arms and hands and fingers — two hands and ten fingers suffice — he can do as much for atoms as a pianoforte player can do for the keys of the piano — just a little more, he can push or pull each atom in any direction. He cannot create or annul...
Síða 665 - May we consider the existence of these molecular states as forming a true basis for Dalton's law of multiple proportions ? If so, then the metals in different chemical combinations will exist in different molecular groupings, and we shall be able by spectrum observations to determine the particular heat-level to which the molecular complexity of the solid metal induced by chemical affinity - corresponds. Examples. — None of the lines of magnesium special to the flame spectrum are visible in the...
