Copy letter from Robert William Frederick Harrison, to Professor Charles Scott Sherrington, Fellow of the Royal Society Sir Michael Foster, who has just returned, has seen Mr Macdonald's paper with its new addendum and has decided that the best way to treat it will be to print it as three papers, in juxtaposition, with the general heading 'Demarcation Current of mammalian Nerve' appearing in each. Is having proofs of the whole prepared and will post early copies to Mr Macdonald. 25 October 1900
