rests, or appreciate in any degree which of them is material to the conclusion and which is not, or even to conjecture whether, taken together, they exclude the hypothesis that it was not a man but a cow or a dog which passed over the ground, and not to-day but yesterday that the marks were made. Dr. Taylor further on makes a display of this inability to appreciate the logical value of scientific facts by asking: "Where is the evidence, scientific or other, that there was evolution? We see these fossils (those of the horse). Huxley _says_ they are as they are because the higher evolved itself out of the lower; we _say_ they are as they are because God created them in series." To recur to the former illustration, it is as if the Indian should show Dr. Taylor the marks on which he relied in his induction, and the doctor should calmly reply: "I see the marks; you _say_ they were made by a man's foot in walking; I, who have never given any attention to the subject, and have never been in the woods before, _say_ they were made by the rain." The fact is that if there were any weight whatever in this kind of talk--if no equality of knowledge were necessary between two disputants--it would enable an ignorant field-hand to sweep away in one sentence the whole science of geology and palaeontology, and even astronomy, and to dispose of every conclusion on any subject drawn from a skilled and experienced balancing of probabilities, or nice mathematical calculation, by simply saying that he was not satisfied with the proofs.
