Four hundred and thirteen (413) volumes were bound this year

With the additions for the past four or five years, the Library 

 has a magnificent start for a collection of periodical and other 

 scientific literature not to be equaled in the city ; there are li- 

 braries much larger, but they are made up of miscellaneous subjects, 

 while that of the Museum is strictly natural sciences.
