Letter from George Manning, Royal Canadian Air Force, 20 Woodington Ave Toronto, to [Henry] Barcroft Has forward [Barcroft's] letter on to Major Bensley - thanks him for including his name on the report. Thinks the findings are very interesting - had expected that he would find a larger proportion of 'fainters' when anoxia and venous occlusion occur together. Asks for some reprints. Has not used the plethysomographic apparatus yet. Would like more clinical experience before continuing in research. Asks if Edholm is still connected with the group. 4 November 1945
