Copy letter from Robert William Frederick Harrison, to R T Glazebrook, Fellow of the Royal Society Directed by Professor Schafer to ask Glazebrook to nominate a second referee for Mr G J Burch's paper "On artificial temporary colour-blindness, with an examination of the colour sensations of 109 persons". The paper has already been reported on by a physiologist and Schafer thinks a physicist would be good. The Physiology Committee will hold their meeting on Tuesday 22. Asks to whom he should send the paper. 12 March 1898
