Copy letter from Robert William Frederick Harrison, to Dr Ernest William Hobson, Fellow of the Royal Society Writes to remind him of a paper by E Cunningham 'On the co-functions - a class of normal functions', which was originally sent to him by Professor Joseph Larmor at the beginning of June, and which has now been in his hands for a considerable amount of time. As it is very desirable that a decision as to publication should be made soon, as the summer vacation approaches, Harrison would be obliged if he would return the paper with the report as soon as he can. 16 July 1908
