We talk very truly of the patience of science; but in this department it would be truer to talk of the impatience of science. Owing to the difficulty above described, the theorist is in far too much of a hurry. We have a series of hypotheses so hasty that they may well be called fancies, and cannot in any case be further corrected by facts. The most empirical anthropologist is here as limited as an antiquary. He can only cling to a fragment of the past and has no way of increasing it for the future. He can only clutch his fragment of fact, almost as the primitive man clutched his fragment of flint. And indeed he does deal with it in much the same way and for much the same reason. It is his tool and his only tool. It is his weapon and his only weapon. He often wields it with a fanaticism far in excess of anything shown by men of science when they can collect more facts from experience and even add new facts by experiment. Sometimes the professor with his bone becomes almost as dangerous as a dog with his bone. And the dog at least does not deduce a theory from it, proving that mankind is going to the dogs--or that it came from them. For instance, I have pointed out the difficulty of keeping a monkey and watching it evolve into a man. Experimental evidence of such an evolution being impossible, the professor is not content to say (as most of us would be ready to say) that such an evolution is likely enough anyhow. He produces his little bone, or little collection of bones, and deduces the most marvellous things from it. He found in Java a part of a skull, seeming by its contour to be smaller than the human. Somewhere near it he found an upright thigh-bone, and in the same scattered fashion some teeth that were not human. If they all form part of one creature, which is doubtful, our conception of the creature would be almost equally doubtful. But the effect on popular science was to produce a complete and even complex figure, finished down to the last details of hair and habits. He was given a name as if he were an ordinary historical character. People talked of Pithecanthropus as of Pitt or Fox or Napoleon. Popular histories published portraits of him like the portraits of Charles the First and George the Fourth. A detailed drawing was reproduced, carefully shaded, to show that the very hairs of his head were all numbered. No uninformed person looking at its carefully lined face and wistful eyes would imagine for a moment that this was the portrait of a thigh-bone; or of a few teeth and a fragment of a cranium. In the same way people talked about him as if he were an individual whose influence and character were familiar to us all. I have just read a story in a magazine about Java, and how modern white inhabitants of that island are prevailed on to misbehave themselves by the personal influence of poor old Pithecanthropus. That the modern inhabitants of Java misbehave themselves I can very readily believe; but
