is taught practically rather than by lectures. It will also serve as a 
vademecum for all amateurs and explorers whenever they are interested 
in the minerals most commonly met. It pre-supposes, however, that 
the student have access to such physical instruments orj chemical rea- 
gents as will carry out the tests required. The elements of all mineral- 
ogy, both chemical and physical, are here embraced. It is difficult to 
see how it could be improved, either in matter or method, unless it be 
in the use of the Miller system exclusively, for the nomenclature of 
crystals. n. h. w. 
A Handbook of Rocks, fo7- use without the microscope. J. F. Kemp; 
with a glossary of the names of rocks and of other lithological tertns. 
Second edition, revised, pp. 185, jsi.so. D. Van Norstrand Company, 
New York, 1900. 
This convenient handbook is here improved by the correction of 
some errors in the first edition, and the enlargement of the glossary of 
names of rocks. It embodies the results of wide study and evinces 
great familiarity with geological literature. Its generalizations are usu- 
ally exact and discreet, but are occasionally, though perhaps not injuri- 
ously, shaded by the personal bias of the author. n. h. w.
