1. His system requires indefinite, almost infinite, ages of time back of the Silurian strata, _i. e._ back of the oldest known remains of life, vegetable or animal, on our globe.[11] That is, he requires for the development of his system an almost infinite extension of time back beyond the earliest traces or proofs of life, vegetable or animal, on our globe. And this, he would have men believe, is the perfection of modern Science!――a science which pushes its sphere _in time_ back indefinitely beyond all known facts upon the bare evidence of theories and assumed analogies!――――But even this gives not the full force of the objection made by true Science to his system. It is not merely that he builds upon assumed facts where no known facts are――which is building upon nothing――but where no facts _can be_, which is building not merely upon negatives but upon impossibilities. There is no room for his assumed facts where he locates them. If Geology proves any thing it proves that vegetable and animal life commenced on our planet as soon as the planet was ready and _not sooner_, and that we have the remains of the earliest living organisms in the oldest fossil-bearing rocks. His scheme is therefore conditioned upon impossibilities and must be false. 2. His system requires a close succession of animal races, differing from parent to offspring by only the least possible amount, with no leaps, no gaps whatever. Thus from monkey up to man the system calls for at least a few scores not to say hundreds of intermediate links. Where are they? His suffering theory cries out for their support: there is no answer. The earth’s surface responds not to the call; even “the depths say――They are not in me!” From the original monad up to man all the way through at least the long line of the vertebrates――reptile, fish, bird, mammal――that is to say, through the serpent tribe; the fish kingdom; the swallow, blackbird and eagle, and especially through the quadruped family――the horse and camel and particularly the monkey household――through all this remarkable line of ancestry, Darwin’s system demands a very gradual upward march by the shortest possible stages of progress, so that the intermediate links must be barely less than infinite. It certainly ought to be very easy to trace a genealogical line so well represented. It is estimated that thirty thousand fossil species have been recognized. How many of these can be formed into this genealogical line from the aboriginal vertebrate――supposed to be aquatic and Ascidian――up to man? Has Mr. Darwin set himself to marshal this proof-line of witnesses to his system? No. Not only has he not _done_ this very appropriate thing, but he has _said_ little, quite too little on this most vital point, in the way of showing what could be done. He reiterates that the geological records are very imperfect. Doubtless they quite fail to come up to meet the demands of his system. It is the fatal weakness of his
