Description

Part of Dorothy Crowfoot Hodgkin's research material concerned with mapping the molecular structure of vitamin B12 by means of X-ray crystallography, c.1950, consisting chiefly of a numbered sequence of 50 X-ray photographs in annotated polythene or cellophane-type bags, together with 8 empty bags annotated with diagrams, one additional photograph relating to penicillin, and 3 manuscript papers. Received in the original card slip-case (without lid) in which the sheets of Ilfex X-ray film (by Ilford Ltd.) were supplied, inscribed on one edge 'B 12 dry' (the box is made of acidic card as well as too tight to house the contents safely).

Cellulose Nitrate (Celluloid) - Tested in November 2023 and found NOT to be CN - probably CA.

Cellophane or Cellulose Acetate sleeves (part of the object)
