88 Report of the President 



and H. von W. Schulte, with 214 pages of text, 31 plates, and 

 48 text figures.

Popular Publications e . . , °* , „ 1 °' , 



of Animals of the Past and a second edition 



of the Guide Leaflet, Our Common Butterflies. 



The technical and popular publications of the Museum, on 

 which the sum of $19,000 has been expended during the cur- 

 rent year, are used in making exchanges with other scientific 

 organizations, and it is estimated that publications received 

 are equivalent in value to the publications sent out. 



On account of the war, the scientific publications received 

 in exchange from abroad during the current year have been 

 fewer than usual.
