And it is a manifest corollary, that any structural alteration which may eventually be produced in the one organ, will not be accompanied by some particular set of structural alterations in the other organs. There will be no necessary correlation of forms. Thus Paleontology must depend upon the empirical method.
The extinct Protamniote, the ancestor of the whole group, belongs in its whole organisation to the reptile class. The genealogical tree of the amniote group is clearly indicated in its chief lines by their paleontology, comparative anatomy, and ontogeny. The group succeeding the Protamniote divided into two branches. The branch that will claim our whole interest is the class of the Mammals.
A day or two before this date the professor of paleontology, J. P. Smith, famed not only for his erudition but for his especial kindness to all geology students especially if they did well in paleontology came to the worrying Senior with a paper that Hoover had written sometime before on a paleontological subject, and said to him: "Look here, you will never pass that examination in the state you are in.
"In the study of paleontology an effort has been made to classify the different periods of man's life on the planet, so that we have the stone age, which is the earliest, the bronze age, and the age of iron." "How far back in the history of the world has evidence been found of the existence of man?"
This attitude of mind is but little comprehended in America, where the emotions dominate all human reactions, and even such dismal sciences as paleontology, pathology and comparative philology are gaudily coloured by patriotic and other passions. The typical American learned man suffers horribly from the national disease; he is eternally afraid of something.
Even Pictet, in the second edition of his Paleontology, still considers Pleurotomaria as extinct, and as belonging to the fossiliferous formations which extend from the Silurian period to the Tertiary. Of the living species found at Marie Galante, nothing is known except the specific characteristics of the shell.
Darwin had become, as he himself says, a veritable Croesus, "overwhelmed with his riches in facts" facts of zoology, of selective artificial breeding, of geographical distribution of animals, of embryology, of paleontology. He had massed his facts about his theory, condensed them and recondensed, until his volume of five hundred pages was an encyclopaedia in scope.
They also supplement the work of the field geologists by making special collections in important districts and at critical horizons; but the paleontologists are not held responsible for areal and structural geology on the one hand, and the geologists are not held responsible for paleontology on the other hand.
For six months I toiled in the mines and in the counting-rooms, for I wished to know every minute detail of the business. Then Perry interested me in his invention. He was an old fellow who had devoted the better part of a long life to the perfection of a mechanical subterranean prospector. As relaxation he studied paleontology.
There seems, then, no escape from the admission that neither physical geology, nor paleontology, possesses any method by which the absolute synchronism of two strata can be demonstrated. All that geology can prove is local order of succession.
