“Why, what is there against him?”

“Oh, I didn’t say there was anything against him. He is a little queer in his ideas—an enthusiast in some branches of science. As far as I know he is a decent fellow enough.”

“A medical student, I suppose?” said I.

“No—I have no idea what he intends to go in for. I believe he is well up in anatomy, and he is a first-class chemist; but, as far as I know, he has never taken out any systematic medical classes. His studies are very desultory and eccentric, but he has amassed a lot of out-of-the way knowledge which would astonish his professors.”

“Did you never ask him what he was going in for?” I asked.

“No; he is not a man that it is easy to draw out, though he can be communicative enough when the fancy seizes him.”

“I should like to meet him,” I said. “If I am to lodge with anyone, I should prefer a man of studious and quiet habits. I am not strong enough yet to stand much noise or excitement. I had enough of both in Afghanistan to last me for the remainder of my natural existence. How could I meet this friend of yours?”

“He is sure to be at the laboratory,” returned my companion. “He either avoids the place for weeks, or else he works there from morning to night. If you like, we shall drive round together after luncheon.”

“Certainly,” I answered, and the conversation drifted away into other channels.

As we made our way to the hospital after leaving the Holborn, Stamford gave me a few more particulars about the gentleman whom I proposed to take as a fellow-lodger.

“You mustn’t blame me if you don’t get on with him,” he said; “I know nothing more of him than I have learned from meeting him occasionally in the laboratory. You proposed this arrangement, so you must not hold me responsible.”

“If we don’t get on it will be easy to part company,” I answered. “It seems to me, Stamford,” I added, looking hard at my companion, “that you have some reason for washing your hands of the matter. Is this fellow’s temper so formidable, or what is it? Don’t be mealy-mouthed about it.”

“It is not easy to express the inexpressible,” he answered with a laugh. “Holmes is a little too scientific for my tastes—it approaches to cold-bloodedness. I could imagine his giving a friend a little pinch of the latest vegetable alkaloid, not out of malevolence, you understand, but simply out of a spirit of inquiry in order to have an accurate idea of the effects. To do him justice, I think that he would take it himself with the same readiness. He appears to have a passion for definite and exact knowledge.”

“Very right too.”
