It is not true, for example, that a fish is a reptile arrested in its development, or that a reptile was ever a fish: but it is true that the reptile embryo, at one stage of its development, is an organism which, if it had an independent existence, must be classified among fishes; and all the organs of the reptile pass, in the course of their development, through conditions which are closely analogous to those which are permanent in some fishes.
The poem of Parmenides in which the cosmogonic speculations occur treats also of the origin of man. The author seems to have had a clear conception that intelligence depends on bodily organism, and that the more elaborately developed the organism the higher the intelligence.
I would make not only the mind, but the body of the organism to depend on the characteristics of the vibrations going on within it. The same vibrations which remind the chicken that it wants iron for its blood actually turn the pre-existing matter in the egg into the required material.
All of which goes hand in hand with the evidence that the skeleton stands directly under the domination of the pituitary. There are certain other singular by-effects of the gland in its relation to the periodic phenomena of the organism like hibernation, sleep, and the critical sex epochs of both sexes.
Sight became a sort of strange and delicate hearing. They so distinctly read their thoughts upon their countenances, that these thoughts took a peculiarly piercing sound that agitated all their organism. They could not have understood one another better, had they shouted in a heartrending voice: "We have killed Camille, and his corpse is there, extended between us, making our limbs like ice."
This is especially true in wrestling, where the vital organism is often compelled to endure a great deal of pressure of this kind. The same is true of American football, although this is too violent for those who are not in an unusually vigorous condition.
How, then, are these all-important solvents and eliminators to be supplied to the organism by total abstinence from food? Prolonged fasting undoubtedly lowers the patient's vitality and powers of resistance.
He seems to think pedigreed dogs are better for his filthy purposes than street curs. They have a higher nervous organism, I suppose. The swine!" "What do you mean?" asked the Mistress, puzzled by his vehemence. "I don't " "You must have heard of Halding and his so-called 'research work," the superintendent went on. "He is one of the most notorious vivisectionists in "
But the new and unaccustomed shepherd on the prairie is apt to give himself much unnecessary trouble. It takes some time to learn that a flock of sheep is like a loosely-knit organism which will not separate or divide if it can help it.
The reptile is strictly limited to one region, the bird can pass from region to region as food becomes scarce. The question of the origin of the feathers can be discussed only from the speculative point of view, as they are fully developed in the Archaeopteryx, and there is no approach toward them in any other living or fossil organism.
