Copy letter from Robert William Frederick Harrison, to Professor Rubert William Boyce, [Fellow of the Royal Society], Pathology School, University College, Liverpool With reference to Boyce's letter of the previous day, Harrison has written to the printers to ask when Boyce can expect the plates of his pigeon paper. Has written to Professor [Charles Scott] Sherrington regarding which of his papers he wishes to have blocks from. A cliche could be obtained of the process-plate block, and he supposes Sherrington has the original negatives from which the colotypes could be made. Will have the matter put in hand as soon as he hears from Sherrington and Boyce. 6 March 1900
