which have been found to be much more widespread as constituents 
of rocks than was supposed when the German edition was published 
three years ago. 
A further reduction in the size of the book is effected by a rather 
free translation, by which an entire sentence is sometimes reduced 
to the position of a short qualifying phrase, and by the omission of 
certain tables of refractive indices, but more especially by the 
exclusion of the references to the occurrences of the various min- 
erals in rocks of foreign localities. To compensate for the latter 
loss, notes on American occurrences have been copiously inserted. 
The style of the language used is clear; the expressions are 
forcible; and, better tnan all else, the reader of the translation may 
rest assured that he is getting the exact thought of the author of 
the original. 
Not only is Mr. Iddings to be commended for his careful trans- 
lation, but Messrs. Wiley & Sons are likewise to be congratulated 
on producing a work of such a pleasant appearance as the book 
ore us. 
The only fault that can be found with the volume is its price. 
It would seem that in view of the fact that the translation will 
- meet with a ready sale in England and America, its price might 
have been placed at such a figure as to enable every one taking a 
course in geology to indulge in the luxury of a few weeks work 
with the beautiful objects in rocks revealed to our eyes when aided 
by the polarizing microscope.— W. S. B
