"It is not impossible," answered the scientist. "We do not deny that some very extraordinary circumstances can be induced by sympathy and antipathy."

"I suppose you do not believe in actual mesmerism, do you?"

"I neither affirm nor deny,—I wait; and until I have been convinced I do not consider my opinion worth giving."

"That is the only rational position for a man of science. I fancy that nothing but experience satisfies you,—why should it?"

"The trouble is that experiments, according to the old maxim, are generally made, and should be made, upon worthless bodies, and that they are necessarily very far from being conclusive in regard to the human body. There is no doubt that dogs are subject to grief, joy, hope, and disappointment; but it is not possible to conclude from the conduct of a dog who is deprived of a particularly interesting bone he is gnawing, for instance, how a man will act who is robbed of his possessions. Similarity of misfortune does not imply analogy in the consequences."

"Certainly not. Otherwise everybody would act in the same way, if put in the same case."

The professor's conversation was interesting if only on account of the extreme simplicity with which he spoke of such a complicated subject. I was impressed with the belief that he belonged to a class of scientists whose interest in what they hope to learn surpasses their enthusiasm for what they have already learned,—a class of scientists unfortunately very rare in our day. For we talk more nonsense about science than would fill many volumes, because we devote so much time to the pursuit of knowledge; nevertheless, the amount of knowledge actually acquired, beyond all possibility of contradiction, is ludicrously small as compared with the energy expended in the pursuit of it and the noise made over its attainment. Science lays many eggs, but few are hatched. Science boasts much, but accomplishes little; is vainglorious, puffed up, and uncharitable; desires to be considered as the root of all civilization and the seed of all good, whereas it is the heart that civilizes, never the head.

I walked by the professor's side in deep thought, and he, too, became silent, so that we talked little more until we were coming home and had almost reached the house.

"Why has Patoff never been in England before?" I asked, suddenly.

"I believe he has," answered Cutter.
