 Periodicals, and 83 Personal Donors. 



The Purchases included 31 Volumes and 6 detached Parts of 

 Works, and 17 Volumes and 18 detached Parts of Works published 

 serially. On January 23rd, 1918, the Council apportioned the sum 

 of £40 from the Balance of the Proceeds of the Prestwich Trust 

 Fund for the purchase of works on Economic Geology. On account 

 of the small number of books on this branch of the subject that 

 are being published at the present time, the whole amount has not 

 been expended in the year under review. By the end of the year 

 the sum of £11 2s. 6d. had been spent on the purchase of 19 

 volumes ; and a special account has been opened for the Balance, 

 which will be drawn on from time to time.
