appendices containing a simple determinative guide and various 

 mineral tables. 



In the description of individual minerals the author first gives 

 the composition, crystallization, physical characters, chemical 

 tests, etc. Practically no abbreviations or headings are used in 

 this section. This makes the descriptions very readable but must 

 detract from the convenience with which the book can be used by 

 a student. The other paragraphs in a typical description are 

 headed : Synthesis, origin, occurrence, localities, uses, produc- 

 tion, etc. Much valuable and interesting information is given in 

 these paragraphs that is not ordinarily found in such books. The 

 typography is very good and the figures are unusually Avell chosen 

 and reproduced. Professor Bailey is to be congratulated on pro- 

 ducing, in an already well-filled field, a book that possesses such 

 individual distinction and character. w. e. f.
