Undated Notes and Drafts

This is entirely autograph manuscript material, written on jotter pads or on loose pages of various format, and sometimes paginated. It is presented under tentative headings according to subject-matter.

Attention is drawn to G.145-G.155 which have been retained as samples of Chain's methods of work, with a miscellany of research ideas, drafts for papers, scientific and personal correspondence all on the same jotter or notepad for later use or typing-up.

G.155 is a folder of bibliographical notes, of interest since Chain left virtually no laboratory notebooks or experimental observations.
