394 The Amerirnn Geologist. December. i904. 
Dr. Washington is himself both a petrographef and a cliemist. The 
methods given are either his own or those of the best workers in the 
field and have been tested by himself. • They are, therefore, prac- 
tical methods. A pleasing, but in this case not unexpected, feature of 
the work is Dr. Washington's evident disposition to give full credit 
to everyone upon whom he has drawn for information. The booK 
should be iri the hands of everyone who has occasion to make rock and 
mineral analyses. - c- P. m.
