He was inspired to further experiment and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. He named the active substance penicillin.

This letter was signed on inside of second leaf. Partly erased red pencil notations on front, slight ink smears on verso, otherwise, fine. $1,650. (#11050)
