ably the whole fund might be expended at once in binding the 
unbound works now on the library shelves, and yet there is, in 
round numbers, only five hundred dollars a year with which to 
bind, buy new books, subscribe to necessary periodicals, and finally 
to complete broken sets of journals and other works. This is 
really pitiable, when we consider how much could be profitably 
expended for these purposes, and when we remember that a good 
library is the sine qua non of scientific progress and study. 
The additions for the year amount to the average sum of 1683. 
Last year the sum total was much larger, 2180, but a larger 
number of works were added by the exchange of duplicates, etc. 
The classification of the year’s increase is as follows :

A small number 
of such works as 
most needed 
it have been 
bound, and a few general or other works have been purchased. A 
few text books and the like have been bought from the receipts of 
the laboratory and deposited in the Library. 
More shelf accommodation is now necessary, and will soon be 
very urgently so. With such changes as this will of course entail, 
the card catalogue should be rewritten on smaller cards, and a 
modern system of reference numbers should be adopted, to avoid 
much labor in the future. Unfortunately this work will require 
considerable money and time for its accomplishment. 
One hundred and twenty-six persons have borrowed eleven hun- 
dred and two books from the Library during the year. 
Publications. 
The Anniversary Memoirs, in celebration of the Society’s fiftieth 
anniversary have, after long delays, just been published. The work 
makes a large and handsome volume of six hundred and thirty- 
five pages, nine portraits and thirty-two plates, besides a number 
of wood-cuts and other illustrations. The history of the Society,
