[The Editor of the Quarterly Journal is directed to make it known to the Public 

 that the Authors alone are responsible for the facts and opinions 

 contained in their respective Papers.] 



* # * The Council request that all communications intended for publication by the 

 Society shall be clearly and legibly written on one side of the paper only, with 

 proper references, and in all respects in fit condition for being 

 at once placed in the Printer's hands. Unless this is done, it will be in 

 the discretion of the Officers to return the communication to the Author for revision. 



The Library at the Apartments of the Society is open every Week Day from Ten 

 o'clock until Five, except on Saturdays (when the hours are from 10 to 1), and 

 except during the fortnight commencing on the first Monday in September, 

 when the Library is closed for the purpose of cleaning. 



Fellows are reminded that, after the completion of Vol. LXXVI 

 (1920), they will not be entitled to receive the Quarterly Journal 

 regularly, unless a subscription at the rate of 10s. per volume is 

 paid in advance, along with their Annual Contribution to the Society. 

 Those Fellows who do not require the complete series can obtain 

 separate parts at the price of 3s. each, if applied for within one year 

 of the date of issue.
