General, and $199.10 for the Rumford, Funds, as the cost of subscrip- 

 tions and binding. Of the appropriation of S50.00 from the Rumford 

 Fund for books, five have been purchased at a cost of $23. 64. 



Although $585.55 from the income of the General Fund was spent 

 for binding, there are still 400 volumes waiting to be bound. There 

 has never been an adequate amount appropriated for binding, and we 

 are now exchanging with more societies and universities than ever 

 before. Societies are now publishing more volumes, and these contain 

 more plates than formerly, which makes the binding more expensive.
