"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."
"Yes, but it may be pushed to excess. When it comes to beating the subjects in the dissecting-rooms with a stick, it is certainly taking rather a bizarre shape."
"Beating the subjects!"
"Yes, to verify how far bruises may be produced after death; I saw him at it with my own eyes."
"And yet you say he is not a medical student?"
"No. Heaven knows what the objects of his studies are. But here we are, and you must form your own impressions about him." As he spoke, we turned down a narrow lane and passed through a small side-door, which opened into a wing of the great hospital. It was familiar ground to me, and I needed no guiding as we ascended the bleak stone staircase and made our way down the long corridor with its vista of whitewashed wall and dun-coloured doors. Near the farther end a low arched passage branched away from it and led to the chemical laboratory.
This was a lofty chamber, lined and littered with countless bottles. Broad, low tables were scattered about, which bristled with retorts, test-tubes, and little Bunsen lamps, with their blue flickering flames. There was only one student in the room, who was bending over a distant table absorbed in his work. At the sound of our steps he glanced round and sprang to his feet with a cry of pleasure: "I've found it! I've found it," he shouted to my companion, running towards us with a test-tube in his hand. "I have found a re-agent which is precipitated by hæmoglobin, and by nothing else." Had he discovered a gold mine, greater delight could not have shone upon his features.
