Nay, it is only the other day that an eminent physiologist, Dr. But a race, once produced, is no more a fixed and immutable entity than the stock whence it sprang; variations arise among its members, and as these variations are transmitted like any others, new races may be developed out of the pre-existing one ad infinitum, or, at least, within any limit at present determined.
It is admitted on all hands that they were once filled with ice, and as the existing glaciers polish and grind down, as before stated, the surface of the rocks, we are prepared to find that every lake-basin in countries once covered by ice should bear the marks of superficial glaciation, and also that the ice during its advance and retreat should have left behind it much transported matter as well as some evidence of its having enlarged the pre-existing cavity.
Some aid can occasionally be derived from a fourth kind of proof, namely, the fact of one deposit including in it fragments of a pre-existing rock, by which the relative ages of the two may, even in the absence of all other evidence, be determined. The first and principal test of the age of one aqueous deposit, as compared to another, is relative position.
How is the existence of this long succession of different species of crocodiles to be accounted for? Only two suppositions seem to be open to us either each species of crocodile has been specially created, or it has arisen out of some pre-existing form by the operation of natural causes. Choose your hypothesis; I have chosen mine.
By this theory he dispensed with the necessity of filling up pre-existing cavities with stratified alluvium, in the manner proposed by M. de Mortillet. I will now explain to what extent I agree with, and on what points I feel compelled to differ from the two distinguished geologists above cited. First.
Darwin, in violation of all observation, you break the barrier between the classes of vegetable and animal life, and suppose every animal to be an "improved" vegetable, you do but carry your difficulty with you into the vegetable world; for, how could there be seeds if there had been no plants to seed them? and if you carry up your thoughts through the vista of the Darwinian eternity up to the primaeval fungus, still the primaeval fungus must have had a humus, from which to draw into its venerable vessels the nourishment of its archetypal existence, and that humus must itself be a "false mark" of a pre-existing vegetation.
"I'll suggest, just to keep the argument going, that speech couldn't have been invented without pre-existing sapience," Jack said. Ruth laughed. "Now you're taking me back to college. That used to be one of the burning questions in first-year psych students' bull sessions. By the time we got to be sophomores, we'd realized that it was only an egg-and-chicken argument and dropped it."
In weapons and cutting tools, the substitution of bronze for stone entails upon him who first makes it a great increase of demand so great an increase that he presently finds all his time occupied in making the bronze for the articles he sells, and is obliged to depute the fashioning of these to others: and, eventually, the making of bronze, thus gradually differentiated from a pre-existing occupation, becomes an occupation by itself.
Among the oldest names of weapons on both sides scarcely any can be shown to be certainly related; -lancea-, although doubtless connected with -logchei-, is, as a Roman word, recent, and perhaps borrowed from the Germans or Spaniards. Only we must, of course, not forget that like pre-existing conditions lead everywhere to like institutions.
The mountain on which God made his revelation bears six names: It is called the Desert Sin, because God there announced His commandments; it is called the Desert Kadesh, because Israel was sanctified there; the Desert Kadmut because the pre-existing Torah was there revealed; the Desert Paran because Israel there was greatly multiplied; the Desert Sinai because the hatred of God against the heathens began there, for the reason that they would not accept the Torah; and for this same reason is it called Horeh, because the annihilation of the heathens was there decreed by God.
