Copy letter from Robert William Frederick Harrison, to Herrn Dr Moritz Cantor, Heidelberg Answers Cantor's enquiries concerning the erasure of the word 'hodie' in a letter of Leibnitz [Leibniz], present as a copy in the MS book LXXXI. Notes there are other words cancelled in the same copy of the letter and that it is full of corrections and alterations, some of which appear to have been made at the same time as the blot obliterating 'hodie'. If Cantor would like Harrison can take steps to have the letter photographed. 6 December 1899
