of Geological Surveys and other public bodies, and 9 volumes of 

 Aveekly periodicals. 



Further, 95 sheets of geological maps were received during 

 the year. 



The number of accessions by donation amounts, therefore, to 

 442 volumes, 410 pamphlets, and 672 detached parts. The Donors 

 during 1922 included 131 Government Departments and other 

 public bodies, 134 Societies and Editors of periodicals, and 102 

 individuals. 



Further progress has been made in the resumption of exchanges 

 with Societies, Government Departments, and other Institutions 

 on the Continent, with which relations had been suspended during 

 the war. The Library now receives the publications of nearly all 

 such Institutions, although in some cases it has been found im- 

 possible to obtain complete sets for the interrupted period. 



During the year 137 volumes have been bound. Owing to the 

 high cost of binding, only the most necessary work of this descrip- 

 tion has been undertaken, and a great many books are at present 

 unbound or awaiting repair, representing the accumulation of several 

 years during which expenses under this heading have been reduced 

 to the minimum. 



The purchases during the year included 11 volumes and 28 de- 

 tached parts of works, and 41 volumes and 48 detached parts of 

 works published serially, and 2 sheets of geological maps. Among 

 these works were the following : —

The number of volumes borrowed from the Library during 1922 

 was 1135. Of this total 663 were taken personally by Fellows, 

 and 472 were sent through the post. In addition, it is estimated 

 that the Library was used for purposes of reference and study on 

 nearly 1500 occasions. 



The List of Geological Literature for 1914 (No. 21) was com- 

 pleted and published during the year under review. The List for 

 the years 1915-19 is at present in the press. These two volumes
