Copy letter from Robert William Frederick Harrison, to Professor Ernest Henry Starling, Fellow of the Royal Society 'Dear Professor Starling, On December 15th last I wrote to Mr H. H. Dale for an Abstract of his paper "On the Islets of Langerhaus in the Pancreas", but have not received any reply. His paper has now been put down for reading next Thursday, I should therefore be much obliged if you would induce Mr Dale to supply a short abstract as soon as possible. Believe me, yours very truly, Robt [Robert] Harrison Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 25 January 1904
