tem and the special senses. It is to be hoped 
that before issuing a second edition, which will 
probably ‘be called for, the author will re-ap- 
portion his space and develop more fully these 
latter subjects. 
The book is fully up to date in its facts. As 
to point of view it represents, like nearly all 
text-books of the physiology of man, that of 
conventional or organ physiology, rather than 
that of the cell.

Analyses Electrolytiques. Par AD. MINET. Mas- 
son et Cie, Paris. 
The first three pages of the first chapter of 
this little volume aim to be historical, but in the 
latter respect are so incomplete that they are 
really misleading. The subsequent pages, de- 
voted to the sources of electricity, the measure- 
ment of current intensity, a description of the 
different apparatus used in electrolytic analysis 
and electrolytic constants, are much more satis- 
factory and really praiseworthy. 
The second chapter pretends to consider 
electrolysis from a qualitative standpoint, but 
is so meager in its details that that feature of 
it would probably have better been omitted. 
The quantitative determination of non-metals 
(the halogens, nitrogen in nitrates and sulphur 
in sulphides) is also considered. 
The third chapter relates to the quantitative 
determination of individual metals. In the 
main the procedures are similar to those al- 
ready described in existing works upon electro- 
chemical analysis. There is no good reason to 
omit the double cyanide of mercury and potas- 
sium in speaking of proper electrolytes for the 
determination of that metal. Under iron ref- 
erence is made to the ‘Procede de Drow,’ 
meaning of course our own Dr. Drown. The 
author seems to have been careless in regard to 
the correctness of names, for there are numer- 
erous oversights of this character scattered 
throughout the entire book. At times there 
seems to have been an effort made to give due 
credit to the various workers in this particular 
field, but oftener there is an absolute neglect as 
to the origin of the methods. 
Had M. Minet ever tried the separation of 
SCIENCE. 
[N.S. Von. X- No. 248, 
copper from silver electrolytically, the reviewer 
sincerely doubts whether he would have recom- 
mended the suggestion given on page 134. Those 
experienced in this direction know that to pre- 
cipitate out the silver as oxalate, wash it, ete., 
is a vexing operation. Why not simply add an 
excess of alkaline cyanide to the solution of the 
two metals and electrolyze at 65°C? The sep- 
aration is then complete and rapid. Other 
methods are not above criticism, but itis not the 
purpose of the reviewer to find fault. His sole 
desire is to see the best given to those who may 
undertake to do work in this field.’ 
The fifth chapter gives in considerable detail 
the work of Hollard in the application of elec- 
trolytic methods to the analysis of alloys, and is 
very meritorious in every respect. One hundred 
and seventy-six pages comprise the entire vol- 
ume, which no doubt will serve well to give one, 
not especially interested or conversant with this 
field of investigation, a very good idea of what 
is being done, but the writer questions whether 
more than that can be fairly claimed for this 
publication.
