Seite 95 - As a great original discoverer in English geology, and especially for his having been the first, in this country, to discover and teach the identification of strata, and to determine their succession by means of their imbedded fossils.
Seite 27 - It proves conclusively that the brain was proportionately smaller than in any other known mammal, recent or fossil, and even less than in some reptiles. It was, in fact, the most reptilian brain in any known mammal.
Seite 107 - Whales the harpoon often pierces the lungs or air passages of the unfortunate victim, and then fountains of blood may be forced high in the air through the blowholes, as commonly depicted in scenes of Arctic adventure ; but this is nothing more (allowance being made for the Whale's peculiar mode of breathing) than what always follows severe wounds of the respiratory organs of other mammals.
Seite 117 - ... blade is somewhat triangular in form, with the base attached to the palate, and the point hanging downwards. The outer edge of the blade is hard and smooth, but the inner edge and apex fray out into long bristly fibres, so that the roof of the Whale's mouth looks as if covered with hair, as described by Aristotle. The blades are longest near the middle of the series, and gradually diminish towards the front and back of the mouth.
Seite 17 - Snakes are in general very quick, and may be adapted to every variation of ground over which they move, yet all the varieties of their locomotion are founded on the following simple process. When a part of their body has found some projection of the ground which affords it a...
Seite 112 - It has never been found in the open sea, but is extensively distributed throughout nearly the whole of the river-systems, not only of the Ganges, but of the Brahmaputra and Indus, ascending as high as there is water enough to swim in. The eyes are exceedingly small and imperfect in structure, and it appears to be quite blind. It feeds on small fish and Crustacea, which it gropes for with its long snout in the muddy water at the bottom of the rivers. The blowhole, as may be seen in the stuffed specimen,...
Seite 108 - They are generally gregarious, swimming in herds or " schools " (so termed by the whalers), sometimes amounting to many hundreds in number, though some species have hitherto only been met with either singly or in pairs. The great commercial value of the oil, which all the Cetacea yield, and the special products useful to man of certain species, as whalebone, spermaceti, &c., cause them to be subject to an unremitting persecution, which has of late greatly diminished their numbers, and threatens some...
Seite 116 - In the female both remain permanently concealed within the bone of the jaw, so that this sex is practically toothless ; but in the male, while the right tooth remains similarly concealed and abortive (as shown in the skeleton by removal of part of the bone which covered it), the left is immensely developed, attaining a length equal to more than half that of the entire animal, projecting horizontally from the head in the form of a cylindrical or slightly tapering pointed tusk, with the surface marked...
Seite 116 - They are found in almost all seas from Greenland to Tasmania, and are distinguished from all their allies by their ferocity, being the only Cetaceans which habitually prey on warm-blooded animals ; for though fish form part of their food, they also attack and devour Seals and various species of their own order, not only the smaller Porpoises and Dolphins, but they also combine in packs to hunt down and destroy full-sized Whales, as wolves do the larger ruminants.
Seite 91 - Skeleton incompletely ossified, with the vertebrae in small number. Gills pectinate ; a narrow gill-opening in front of the pectoral fins. Mouth narrow ; the bones of the upper jaw generally firmly united. A soft dorsal fin, belonging to the caudal portion of the vertebral column, opposite to the anal ; sometimes elements of a spinous dorsal besides. Ventral fins none, or reduced to spines. Air-bladder without pneumatic duct.
