58 PROCEEDINGS: BOSTON SOCIETY NATURAL HISTORY. 
Two sides of the basement room are fitted with shelves providing 
for about 4,000 volumes. This has cost $121. 
In the annual report for May, 1894, I gave a list of the journals 
and serial publications received by the Society. The list soon to be 
issued by the Boston Public Library will show not only those taken 
currently by the Society but also by the libraries of Boston and 
vicinity. It will not, however, include discontinued serials, and as 
these are numerous and important I append to this report a list of 
those on our shelves. 
A gift of $250 for the library from Miss H. O. Cruft w r as most 
timely, as it enabled us not only to purchase some recently published 
books but also to increase the number of volumes bound during the 
year.
