Copy letter from Robert William Frederick Harrison, to Dr John Allen Harker The bill from Messrs Harrison & Sons which Harker sent with his letter of 20 June and which Harrison returns with this [not enclosed] appears correct. On checking the Society's files, Harker ordered 150 copies, 50 of these at his own expense. Encloses a blank form from which Harker will see particulars as to the price charged for plates [not enclosed], but not text. The cost per copy charged Harker is one shilling and a fraction of a penny. Harrison notes he is not the printer of the '[Philosophical] Transactions [of the Royal Society]', but the bearer of the same name. 22 June 1900
