Text-book of mineralogy , with an extended treatisee on crystallogra- 
phy and physical mineralogy . Edward Salisbury Dana. New edi- 
tion, entirely re-written and enlarged, with nearly 1000 figures and a col- 
ored plate. 8vo, viii -f 593 pages, $4.00, John Wiley and Sons, New 
York: 1898 
This work takes the place, in most elementary and classroom work, 
of the "System of Mineralogy," by Dana, of which it is, in its descript- 
ive portion, an abridgment. Its physical and chemical portions, espe- 
cially that relating to optical methods, are more full than the same in 
the larger book, so that by this text book the modern student may be 
made acquainted with nearly all the methods of mineralogical investi- 
gation. It is to be commended for its adoption of the Miller system 
of symbols, and for the use of symmetry as a basis of classifying all 
crystal forms, making thirty-two groups. n. h. w. 
Manual of Determinative Mineralogy, ivith an introduction on Blow- 
pipe Analysis. George J. Brush. Revised and enlarged, with entire- 
ly new tables for the identification of minerals, by Samuel L. Pen- 
field. 8vo, pp. X -(- 312, 15th edition. John Wiley and Sons, New 
York: 1898. 
This excellent work is still further improved by the addition of an 
entirely new chapter, devoted to the physical properties of minerals, 
especially crystallography. The remainder of the introductory portion 
is essentially the same as in the last (14th) edition, but the tables which 
have been for a long time familiar to the American student, are ampli- 
fied and altered so as to cover nearly 800 species, and the new facts of 
mineralogy, their general scope and plan being the same as before. 
The work therefore is no longer a treatise on blowpipe manipulation 
and determination, but becomes a general manual for the determina- 
tion of minerals by all methods excepting the study of their optical 
characters. N. H. w.
