given, but the ‘approximate values generally 
used’ need revision (or deletion) when they range 
up to a discrepancy, in the case of zinc, of more 
than a half per cent. The author uses a nomen- 
clature that we consider objectionable, though of 
course it is not original, as in the case of the 
analysis of barium chloride. Here we 
“estimation of barium” and “estimation of 
chloride.” The word “chloride” is used to in- 
dicate the combined chlorine, and as this word 
has for some generations indicated the whole salt, 
a new and additional meaning is given to an old 
word, and this leads to confusion. Moreover, this 
method is not consistent because, while it tries to 
distinguish between free and combined chlorine, 
there is no attempt made to distinguish between 
free and combined barium. 
Mr. Hampshire (2) gives the usual selection of 
volumetric work that is prescribed for elementary 
students, but his book has a special value in in- 
cluding, after each section, short instructions for 
the examination of those pharmaceutical prepara- 
tions that are appropriately analysed by the 
method described. Mr. Thole’s “Qualitative 
Organic Analysis’’ (4) contains a considerable 
amount of information in a convenient form. It is 
gratifying to see that the author aims at treating 
the subject ‘“‘on simple and logical lines.”’ But there 
are other logical methods of work, and, at the same 
time, simpler systems from a practical point of 
view, besides the one that begins with six tests 
for elements, and follows these with more than a 
dozen “additional preliminary tests,” with six more 
to be added “if the substance is carbocyclic,” be- 
fore going to the “distinguishing and confirmatory 
tests.” It ought not to be a question of the choice 
between this tedious method and the random 
guessing referred to in the introduction, and which 
admittedly is far too general. These three 
volumes have been carefully prepared and will take 
their places as useful laboratory text-books. 
The other two volumes are not beginners’ books. 
Mr. Herbert B. Stocks, in his “ Water Analysis ”’ 
(3), solves the old controversy as to the respective 
merits of getting at the organic matter 
Wanklyn’s distillation with alkaline permangan- 
ate and Frankland’s combustion for carbon and 
nitrogen, by giving both. Similarly he gives both 
Clark’s soap method and Hehner’s titration 
method for hardness. A great deal of the book 
is very familiar reading. The author rightly. says 
that the biological examination requires separate 
treatment. When he says that the microscopical 
examination is included, we turned with interest 
to this heading and were disappointed to find that 
only a page is devoted to it.

a volume of an essentially different character from 
any of the preceding. It contains a description 
of methods of air and gas analysis that the author 
has found useful in connection with experimental 
work in physiology, chemistry, and hygiene. The 
practical details of the methods are many of them 
original, and the description of them gives exactly 
what the worker in this branch of analysis would 
wish to know. The larger apparatus for air 
analysis has a gas-measuring vessel that holds 
21 c.c. and gives readings to o’oo1 c.c. Absorp- 
tions are done in attached pipettes, and a control 
tube does away with the need for barometer and 
thermometer. A smaller portable apparatus 
allows of an error limit of ‘or per cent. Other 
portable apparatus for special purposes are 
described, such as for small percentages of carbon 
dioxide, and the examination of the air in mines. 
The recognition and estimation of small propor- 
tions of carbonic oxide in air by means of the 
blood test are fully dealt with. Flame methods 
of estimating oxygen and methane are given, and 
the detection of various poisonous gases and the 
estimation of dust are shortly described. It is 
a thoroughly practical book, and deals with this 
important subject concisely and yet fully.

In his most recent book Sir Harry Johnston has 
re-written several articles that have appeared in 
various journals and included some lectures on 
colonial subjects. | Despite the diversity of sub- 
jects here treated there runs through all the broad 
views of a man who has seen much and travelled 
far, and an attempt to give an anthropological 
explanation to the matters dealt with. The foreign 
relations and colonial aspirations of Germany, 
however, do not concern us here. The opening 
chapter consists of an earnest appeal for the recog- 
nition of anthropology by the Government, and 
we hope that some of our legislators will take it 
to heart. The Royal Anthropological Institute has 
only one underpaid official, not “two paid officials ” 
(p. 5), and the total membership is but 508; it will 
be a happy day when it “scarcely reaches to two 
thousand” (p. 8). The chapters on Ireland are of 
considerable interest, and contain some first-hand 
observations, but we doubt if portions of them
