young men, seemingly very raw, and not appearing like 

 cultivated and intelligent youth. Dr. Pearson usually came 

 into the lecture-room quite in dishabille but half dressed, 

 and the air of things was not up to the dignity of a lecture- 

 room. I felt that I was out of place, and in company to 

 which I did not belong. Some of Dr. Pearson's own discov-

 year. Returning with a companion from Hyde Park, 

 through Piccadilly, we stopped at the shop of a chemist 

 and apothecary, near Albany House. This shop it being 

 evening was surrounded by a large crowd of people who 

 were attracted by the brilliant exhibition of gas-light. It
