Letter from J H G [John Henry Gaddum], Pharmacological Laboratory, 17 Bloomsbury Square, London, to [Leonard George] Goodwin Gaddum has been reading a paper by Greer and others and was surprised to find that judging from their published tracings, they did not have convincing evidence of any effect on the nictitating membrane from stimulation of the hepatic nerves. He thinks they should get decent tracings of n.m BP and uterus and compare them with nonadrenaline injected I.V. and into the hepatic nerve. Small pencil sketch verso. no date [November 1939]
