Various foetuses getting nitrogen. Film 22.

1936-39.

1 film reel (06 min.) : silent, black and white, 16 mm.

This is one of 27 films which were discovered in a wooden box in the Department of Anatomy, University of Cambridge, in July 1974. Examination of the script of the titles indicates that they are at least part of the collection from the experiments of Joseph Barcroft largely on the foetus in 1939. The collection is not complete, and the films seem to have been labelled firstly by Joseph Barcroft and secondly by two other methods. The order ascribed to the collection has been attributed to D. H. Barron.

Annotations on the box: Film 22. Group 1. Sub Group 2. No.2. OK for projection.

Mixed lengths of film with different edge codes. Half-way through the film has been joined the wrong way up so half the film is correct and the other half isn't regardless of which way it is run.

Sir Joseph Barcroft and Dr D. H. Barron. Photographer Mr W. Freeman.
