Copy letter from Robert William Frederick Harrison, to J H Smith The engraving of the illustrations for the paper by himself and Professor [Osborne] Reynolds on a 'Throw-Testing Machine' is now going forward. The scale drawing of the apparatus is only being reproduced, not the photograph, as agreed. Asks him to insert a mention into the text of the missing bed-plate in the drawing, and any other such needful points. 16 June 1902
