having been bestowed upon it in England, except in a slight way, 
we believe, by Forbes'and Sorby; in this country it has suffered 
almost complete neglect, though undoubtedly a few will by this vol- 
ume be stimulated to special research in a department promising 
interesting results. The present volume will therefore form the 
starting point, a basis of comparison for future American micro- 
geologists. Mr. King and his assistants, Messrs. S. F. Emmons and 
rnold Hague, made large collections of crystalline rocks along the 
Fortieth Parallel in the western United States. Professor Zirkel 
was invited to New York to make a preliminary examination of 
the collection, thus becoming acquainted with the geological dis- 
tribution, relative age and reciprocal connections of the rocks, so 
that their minute chemical and mineralogical constitution has 
been made from a geological view, greatly enhancing the value 
of Zirkel’s labors. At home the author carefully studied more than 
twenty-five hundred thin sections of these rocks, crystalline or of 
volcanic origin, and he pays Mr. King the compliment that “your 
original designations should almost never be altered or corrected.” _ 
_ The plates are excellent and well. colored.

is the joint production of Prof. Jordan and H. E. Copeland, and 
is avaluable contribution to our ichthyological literature, bringing
