Page 386 - Chile, when my servant, noticing that one of the horses was very restive, went to see what was the matter, and fancying he could distinguish something, suddenly put his hand on the beast's withers, and secured the vampire.
Page 386 - The Vampire bat is often the cause of much trouble, by biting the horses on their withers. The injury is generally not so much owing to the loss of blood, as to the inflammation which the pressure of the saddle afterwards produces. The whole circumstance has lately been doubted in England; I was therefore fortunate in being present when one (Desmodus d'orbignyi, Wat.) was actually caught on a horse's back.
Page 353 - In the myology of the dog, the insertion of the tendon of the external oblique muscle of the abdomen presents some interesting peculiarities. The outer and posterior fibres of this muscle end in a fascia, which is partly continued over the thigh AS fascia lata, and partly forms an arch (Poupart's ligament) over the femoral vessels ; by its inner end it is inserted into the outer side of a triangular fibrocartilage, the broad base of which is attached to the anterior margin of the pubis, between its...

Among the higher apes the orang comes nearest to man in the number of ribs (twelve pairs)' and form of the cerebral hemispheres, but differs from him in other respects, especially in the limbs, more than do the gorilla and chimpanzee. The chimpanzee approaches man most closely in the character of its cranium, dentition and proportional size of its arms. The gorilla is more man-like in the proportion of the leg to the body,...
Page 7 - Vertcbrata are distinguished from all other animals by the circumstance that a transverse and vertical section of the body exhibits two cavities completely separated from one another by a partition. The dorsal cavity contains the cerebro-spinal nervous system ; the ventral, the alimentary canal, the heart, and usually a double chain of ganglia, which passes under the name of the
Page 148 - Dipnoi" after the Teleostei and as the sixth order of fishes. He failed even to find any extinct Dipnoans, and concluded his observations on the group with the statement that •' It is a remarkable circumstance that, while the Dipnoi present, in so many respects, a transition between the piscine and the amphibian types of structure, the spinal column and the limbs should be not only piscine, but more nearly related to those of the most ancient Crossopterygian Ganoids than to those of any other fishes."2...
Page 419 - Leiotriehi are divisible into : '1. The Australioid group, with dark skins, hair, and eyes, wavy black hair, and eminently long prognathous skulls, with well-developed brow ridges, who are found in Australia and in the Dekhan. ' 2. The Mongoloid group, with, for the most part, yellowishbrown or reddish-brown skins, and dark eyes ; the hair being long, black, and straight.

Of greater significance and importance is the slope of the face or the cranio-facial angle, which in the different races of mankind and in man degenerate, presents wide variations. A line drawn from the anterior extremity of the premaxilla to the anterior extremity of the basi-cranial axis may be taken to represent the facial axis, and the angle included between these two is the cranio-facial angle, It varies with the extent to which the face lies in front...
Page 32 - The pisiforme is a sesamoid bone developed in the tendon of the flexor carpi ulnaris, which has nothing to do with the primitive carpus. The centrale is not represented in a distinct shape, having proba bly coalesced with one of the other elements of the carpus.
Page 131 - On page 131 of the same work he says, "the spinal " column appearing to terminate in the centre of a wedge-shaped " hypura! bone, to the free edges of which the caudal fin rays are "attached, so as to form an upper and a lower lobe, which are " equal or sub-equal. This characteristically Teleostean structure "of the tail-fin has been termed homocercal — -a name which may "be retained, though it originated in a misconception of the re" lation of this structure to the heterocercal condition.
