Copy letter from Robert William Frederick Harrison, to Professor Wyndham Dunstan, Fellow of the Royal Society 'Dear Professor Dunstan, I find I have neglected to answer a mention in your letter acknowledging the cheque for Mr Mahon. The usual practice is for the administration of a grant, when the administration is completed, simply to report to the Committee that fact, & the mode in which he has made the payments. Believe me, very truly yours, Robt [Robert] Harrison'. 7 March 1906
