As may be seen from the fourth cohimn of the first table on p. 26 there 



was a markt increase in the sales of publications during the year. This in- 



- , r T5 Lf ^- crease is likely to continue until a balance between the 

 Sales of Publications •' 



and Value of Those demand and the supply is reacht. There seems to be no 

 on Hand. doubt that this method of distributing the publications of 



the Institution is at once the most equitable, practicable, and economical at 

 present attainable. 



At the end of this fiscal year there were in storage in the Bond Building, 

 Washington, D. C, 33,732 volumes, having a sale value of $61,829.80; and in 

 storage in the Geophysical Laboratory, Washington, 24,941 volumes, having 

 a sale value of $54,350. The total value of books on hand is therefore $116,- 

 134.80. In addition to these books there are 23,305 numbers of the Index 

 Medicus on hand, having a sale value of $9,601. All of these books will be 

 placed in fire-proof storage vaults on removal to the Administration Building.
