Copy letter from Robert William Frederick Harrison to Sir William Ramsay KCB, FRS 'Dear Sir William, I have had enquiries from a foreign correspondent about the Radium Institute as to which I have no official particulars. I understand that you are connected with it, and shall be greatly obliged if you can send me any printed statement of other information that exists as to its constitution and purpose for me to send my acknowledgment.' 13 April 1910
