The few genera now surviving are the descendants of the tribes which swarmed in the Devonian seas. The side fins, which correspond to the limbs of the higher vertebrates, are quite unlike those of most modern fishes. Their rays, instead of radiating from a common base, fringe a central lobe which contains a cartilaginous axis. The teeth of the Devonian ganoids show a complicated folded structure.
This lust thus begun, afterwards increases, and as it increases it despises and breaks through all bounds of the love of the sex, and exterminates itself, and from a lascivious, corporeal, and fleshly love, becomes cartilaginous and bony; and then, from the periosteurns, which have an acute feeling, it becomes acute.
The most curious point about the male salmon is that during the breeding- season, besides a slight change in colour, "the lower jaw elongates, and a cartilaginous projection turns upwards from the point, which, when the jaws are closed, occupies a deep cavity between the intermaxillary bones of the upper jaw."
The walls of the windpipe are strengthened by a series of cartilaginous rings, each somewhat the shape of a horseshoe or like the letter C, being incomplete behind, where they come in contact with the oesophagus. Thus the trachea, while always open for the passage of air, admits of the distention of the food-passage. The Bronchial Tubes.
His only resource, therefore, was to try to drown Mr Glowry's voice; and, having no other subject, he continued his description of the ear, raising his voice continually as Mr Glowry raised his. 'When your cousin Marionetta, said Mr Glowry, 'whom you profess to love whom you profess to love, sir 'The internal canal of the ear, said Scythrop, 'is partly bony and partly cartilaginous.
This primitive fin, which Gegenbaur first recognised, is attached to the vertebral column by a simple zone in the shape of a cartilaginous arch. It is also found in modified form in some of the actual sharks and pikes. Human skeleton. Skeleton of the giant gorilla. The little or fifth toe is developed from the lower end of the fin-rod.
The many-toed fin had been used almost solely for motion in the water; it had now also to support the body in creeping on the solid ground. This led to a modification both of the skeleton and the muscles of the limbs. The number of the fin-radii was gradually reduced, and sank finally to five. But these five remaining radii became much stronger. The soft cartilaginous radii became bony rods.
The membrane of the nose will always exhibit marks of inflammation, and particularly in the frontal sinuses and ethmoidal cells; and I have observed the portion of membrane on the septum, or cartilaginous division of the nostrils, between the frontal sinuses and ethmoidal cells, to be studded with small miliary tubercles.
"The condor is a true Sarcoramph in fact, one of the most marked features of this bird is the fleshy cartilaginous crest that surmounts his head and part of his beak. This, however, is only found upon the males, as the female birds are not crested in a similar manner. The condor, when in full plumage, might be called a black-and-white bird.
