About this work

Also known as

The development of the righting movements in sheep. V Film 14.


Part 1; the film starts with footage of adult and newborn lambs rising from using a characteristic movement of their legs. The purpose of the film is to trace this movement back to the early developmental foetal stages from 38 days onwards. The foetus appears to 'right' itself in the uterine sac when stimulated. which starts with an intertitle about the righting movements of sheep: the first foetus is at 38 days onwards. The foetal sheep's head and dorsal spine respond to stimulation, although the legs do not to begin with. Identifiable righting movements begin at 49 days. These later sheep foetuses are removed from the amniotic sac.



Physical description

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.
