Copy letter from Robert William Frederick Harrison, to Dr Frederick Walker Mott, Fellow of the Royal Society Sir John Bradford wishes for Harrison to communicate two points in connection with the publication of the paper by J G Wilson and F H Pike on 'The semi-circular canals of the ear', which Mott communicated for 'Philosophical Transactions [of the Royal Society]', and which is about to go to print. It is suggested that the experiments appear to be destructive of the whole labyrinth, the title should be modified by substituting 'labyrinth' with 'semi circular canals'. Some of the illustrations could be left out, and the statement concerning the discovery of the galvanic nystagmus is not historically accurate. 30 July 1912
