Dr Peak correspondence: Professor Alexander Fleming (St Mary's Hospital, Paddington, London)

Two copy letters to Fleming, referring to the enclosures of PEN Reports, and a single letter (16 April, typescript, signed) from Fleming to Peak referring to a photographic print: "In reply to your letter [not in the file] I have no negative from which you can make copies of the photographic print. Actually the print is not itself a negative, for it is my custom to keep notes of that type of culture by using the culture plate as a negative and printing direct onto bromide paper."
