sis, it seems to the reviewer that it would be well to change the title to 
Blowpipe Analysis and Determinative Mineralogy, which would then 
indicate the natural order of considering these subjects and the one 
followed in the book. 
The new text is admirably written and of especial value because of 
the discriminating judgment that has been shown in selecting the 
characteristic tests for the elements. When no really satisfactory 
blowpipe test for an element exists the author recommends a test em- 
ploying the wet methods. In order to make the work as complete as 
possible tests for the rarer elements are included but appear in finer 
print. Valuable hints concerning the best quantity of material to be 
used in each case and little “ tricks” of manipulation which are usually 
only learned after considerable experience in applying the methods 
abound in the book. Mineralogists generally will rejoice to see this 
valuable work brought up to date by so experienced and so accurate 
a mineralogist as Professor Penfield and will look forward with inter- 
est to the appearance of the revised tables. The author announces in 
his preface that he intends to add a chapter to the work so as to treat 
briefly ere and the physical properties of minerals— Wm.

Chudzinski on the Facial Muscles.’—M. Chudzinski, who for 
many years was the preparateur of anatomy, and the active colleague 
of Paul Broca, has just published a work of well matured thought, the 
result of dissections carried on by the author during twenty-five years. 
This paper comprises a study of the muscles of the face and neck in 
many different races of men, their variations, their anomalies, and 
their analogies and differences with those of the monkeys. When it is 
considered that these muscles are the ones that control the physiog- 
nomy, that is to say, control the expression of mind, one can appreci- 
ate the interest whirh this work of M. Chudzinski will have, not only 
for anatomists, but also for anthropologists and artists.
