The President drew the attention of the Fellows to the subjoined intimation on the Billet : — 
It will be proposed and seconded at the Ordinary Meeting on 10th January 1921 that Rule VI 
read as follows : — 
“ Each Fellow shall, before he is admitted to the privileges of Fellowship, pay an admission 
fee of three guineas, and a subscription of three guineas for the year of election. He shall continue 
to pay a subscription of three guineas at the beginning of each session so long as he remains a 
Fellow. A Fellow may compound for the annual subscriptions by a single payment of fifty 
guineas, or on such other terms as the Council may from time to time fix. 
“ Each Fellow who was elected previous to December 1916 shall pay four guineas at the 
beginning of each session until he has made ten annual payments as reckoned from the year of 
election, and thereafter three guineas at the beginning of each session until he has completed his 
twenty-fifth annual payment. Each Fellow who has completed or shall complete his payments 
shall be invited to contribute one guinea per annum so long as he remains a Fellow, or to pay 
a single sum of ten guineas.”

The President proposed that Rule VI in its amended form should read as follows, and this 
was agreed to with the suggestion that an explanatory footnote should be added to obviate 
any ambiguity. 
“Each Fellow shall, before he is admitted to the privileges of Fellowship, pay an admission 
fee of three guineas, and a subscription of three guineas for the year of election. He shall 
continue to pay a subscription of three guineas at the beginning of each session so long as he 
remains a Fellow. 
“ Each Fellow who was elected subsequent to December 1916 and previous to December 1920 
shall also pay a subscription of three guineas at the beginning of each session so long as he 
remains a Fellow. 
“ Each Fellow who was elected previous to December 1916 and who has not completed his 
twenty-five annual payments shall, at the beginning of each session, pay three guineas or four 
guineas, according as he has or has not made ten annual payments as reckoned from the year of 
election. Each Fellow who has completed or shall complete his payments shall be invited to 
contribute one guinea per annum or to pay a single sum of ten guineas. 
“ A Fellow may compound for the annual subscriptions by a single payment of fifty guineas, 
or on such other terms as the Council may from time to time fix,”
