Is This Fellow's Temper So Formidable?

Stamford says he has no idea what Holmes intends to go in for. He is sure to be at the laboratory from morning til night, returned his companion. The halborn 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 could imagine his giving a friend a little pinch of the latest vegetable alkaloi, not out of malevolence, you understand, but simply out of a spirit of inquiry. It approaches to cold bloodedness.
