Collins's Advanced Science Series. Mineralogy. By J. H. 
Collins, F.G.S. Vol. II. Systematic and Descriptive 
Mineralogy. London and Glasgow: W. Collins, Sons, and 
Co., Limited. 
Of all departments of natural science Mineralogy is probably 
the least generally popular. It has not shared in the impulse 
o-iven to Botany and Zoology by the Darwinian reformation, and 
outside a very limited circle it has neither friends nor enemies. 
The author, in his Preface, pronounces it to be “ little more than 
a dictionary of minerals," and as such it may he considered ac- 
curate and complete. 
The classification adopted is essentially that of Dana, Brooke, 
Miller, and Nicol, somewhat modified by the author. 1 he 
mineral species are arranged under the heads of Native Ele- 
ments, Pyritoids, Haloids, Chlorides, Spathoids, Silicates, and 
Hydrocarbons. _ . 
An Appendix gives the meteoric minerals, and certain mine- 
rals whose composition is either indefinite or has not been 
properly ascertained. 
The work, like almost every scientific manual published in 
England, is written with reference to the “ Science and Art 
Department,” but it has the more satisfactory featuie of being 
also adapted to the use of practical working miners, quarrymen, 
and field geologists.
