 ... tail the plane of the section, as is seen in figure 5I, passes through the posterior end of the embryo no less than four times. In the most posterior of these four sections of the tail, beginning slightly caudad to the section here shown, is seen a small cavity which may be called the post-anal gut, pag.

... longitudinal and transverse muscles, and usually has paired pouches extending out from it into the body parenchym.

There is no anal opening, but indigestible material is still cast out ...

... rather hazy and speculative contribution on Okenian lines to the problem of the relation of Arthropods to Vertebrates, likening the carapace of Crustacea to an enormously developed hyoid, the appendages of the tail to the ventral and anal fins of fish. The masticatory organs of Arthropods were jaws disjointed at their symphysis; antennae, nostrils turned ...

... gratification is gained through erogenous zones, that is, certain areas of the body which are peculiarly sensitized to sexual excitations. Among these erogenous zones may be mentioned the mouth, lips, tongue, anal region, the neck of the bladder as well as various skin areas and sense organs. Already in 1879, Lindner, a Hungarian pediatrist, devoted a penetrating study to the sucking or pleasure-sucking of the child. Freud emphasizes that the ...

... their humble happiness; for unlike ours, the element in which they live is a stream which must be constantly resisted. From time to time they nibble the weeds at the bottom or overhanging their nests, or dart after a fly or a worm. The dorsal fin, besides answering the purpose of a keel, with the anal, serves to keep the fish upright, for in shallow water, where this is not covered, they fall on their sides. As you stand thus stooping over the bream in its nest, the edges of the dorsal and caudal fins have a singular ...

... it could no longer supply food enough for his growing body. There were times when he felt decidedly hungry. And other changes had come while he lay and waited in the gravel. The embryonic fin which had made his tail so like a paddle was gone, the true dorsal and caudal and anal fins had taken their proper shape, and he looked a little less like a tadpole and a little more like a fish. He was stronger than he had been at first, and he was losing his dread of the sunlight; and so at last he left the gravel-bed, to seek his rightful place in the ...

... spring, when one day a large female trout gulped down one of her male friends, nearly one third her own size, and went around for two days with the tail of her liege lord protruding from her mouth! A fish's eye will do for bait, though the anal fin is better. One of the natives here told me that when he wished to catch large trout (and I judged he never fished for any other,—I never do), he used for bait the bullhead, or dart, a little fish an inch and a half or two inches long, that rests on the ...
