Copy letter from Robert William Frederick Harrison, to F R Low, Editor of 'Power', 505 Pearl Street, New York, United States of America The titles of papers to be read before the Society are published weekly each Tuesday in 'The Times' and records can be found in 'Nature'. There is no existing arrangement for the supply of printed papers, other than one which allows an author when his paper has been passed for press, to notify the Society of any special periodical that he would like a copy to be sent. Papers appear promptly in the 'Proceedings [of the Royal Society]' which can be subscribed to for 15 shillings per volume of the physical series, of which about two volumes appear a year. 6 August 1907
