Page 82 - The sixth age shifts Into the lean and slipper'd pantaloon, With spectacles on nose and pouch on side, His youthful hose, well saved, a world too wide For his shrunk shank ; and his big manly voice, Turning again toward childish treble, pipes And whistles in his sound. Last scene of all, That ends this strange eventful history, Is second childishness and mere oblivion, Sans teeth, sans eyes, sans taste, sans everything.
Page 20 - Not being able to appreciate or conceive of the distinction between the psychical phenomena of a Chimpanzee and of a Boschisman or of an Aztec, with arrested brain growth, as being of a nature so essential as to preclude a comparison between them, or as being other than a difference of degree, I cannot shut my eyes to the significance of that all"pervading similitude of structure — every tooth, every bone, strictly homologous — which makes the determination of the difference between Homo and...
Page 20 - Peculiar mental powers are associated with this highest form o' brain, and their consequences wonderfully illustrate the value of the cerebral character ; according to my estimate of which, I am led to regard the genus Homo, as not merely a representative of a distinct order, but of a distinct subclass of the Mammalia, for which I propose the name of
Page 53 - ... retired within its shell, they would still keep their hold, and allow themselves to be carried into the shell with the snail, and although they became enveloped in the mucous secretion, it very seldom appeared to adhere to their bodies.
Page 23 - I have already adverted to the illustration of affinity to the oviparous Vertebrata which the Three-toed Sloths afford by the supernumerary cervical vertebrae supporting false ribs and by the convolution of the windpipe in the thorax ; and I may add that the unusual number — three and twenty pairs — of ribs, forming a very long dorsal, with a short lumbar region of the spine in the Two-toed Sloth, recalls a lacertine structure. The same tendency to an inferior type is shown by the abdominal testes,...
Page 29 - Bos. A well-marked, and at the present day very extensive subordinate group of the Artiodactyles, is called Ruminantia, in reference to the second mastication to which the food is subject after having been swallowed; the act of rumination requiring a peculiarly complicated form of stomach. The Ruminants have the
Page 129 - Wings nearly limpid ; veins black, testaceous at the base ; discal transverse vein slightly curved and oblique, parted by much less than its length from the border, and by much more than its length from the prsebrachial transverse vein.
Page 23 - CHEIKOPTERA, with the exception, of the modification of their digits for supporting the large webs that serve as wings, repeat the chief characters of the Insectivora ; but a few of the larger species are frugivorous, and have corresponding modifications of the teeth and stomach. The mammae are pectoral in position, and the penis is pendulous in all Cheiroptera. The most remarkable examples of periodically torpid Mammals are to be found in the terrestrial and volant Insectivora. The frugivorous Bats...
Page 12 - Classification parallelique des Mammiferes,' published in 1845, raises the Marsupialia to the rank of a distinct class, and literally exemplifies the idea of Cuvier by placing its subdivisions, as orders, in parallel equivalents with the orders of the Placentalia. It does not appear, however, that Cuvier meant to do more than indicate certain relations of analogy ; just as the relation of the pedimanous and frugivorous Marsupials to the pedimanous Quadrumana of S.
Page 6 - The teeth of the Mammalia usually consist of hard unvascular dentine, defended at the crown by an investment of enamel, and everywhere surrounded by a coat of cement.
