described by Prof. Zirkel, of Leipsig, Germarry, in Vol. 

 VI. of the elaborate reports of that careful survey. In 

 the adjoining room are the fossils, rocks and minerals 

 collected by Prof. Raphael Pumpelly during his exten- 

 sive travels in California, China and Japan, and the 

 specimens upon which he has prepared many scientific 

 papers. 



In the same room are the lithological collections of 

 Major T. B. Brooks, which contain the rocks described 

 by him and Prof. Julien in the Geological Reports of the 

 States of Michigan and Wisconsin ; also a full series 

 from Austria, identified by the lithologist of the survey 

 carried on by that Government, and a similar series rep- 

 resenting the lithological work done by the Geological 

 Survey of Sweden. 



The lithology of New York and other States received 

 in the Hall Collection fills 78 boxes of If cubic feet each, 

 and contains the many sections across the State made 

 by Mather and others. The Geological Survey of New 

 Jersey have forwarded specimens of their clays, and will 

 hereafter send, year by year, specimens illustrating the 

 progress of their work. 



The 2,000 lithological specimens received from Prof. 

 Hitchcock are each labeled by him, and illustrate fully 

 the volumes published by his survey. 



Arrangements are being perfected for the rapid in- 

 crease of this remarkable amount of valuable material, 

 purchased or deposited with us, for the use of those con- 

 nected with the surveys of the various States or the 

 nation. 



Prof. M. E. Wadsworth, of the Geological Survey of 

 California, worked during a part of the summer on the 

 specimens described by Prof. Zirkel, and Prof. McGold-
