of men of repute. Under the section dealing 
with sewage purification, there is no mention 
whatever of the work done by the Massachusetts 
Board of Health. 
The appendix is voluminous and consists 
largely of extracts from previous papers pub- 
lished by the authors during the years 1866 to 
1891. W. P. MAson. 
Laboratory Manual, Experiments to Illustrate the 
Elementary Principles of Chemistry. By H. 
W. Hitityer, PH.D., Assistant Professor of 
Organic Chemistry in the University of Wis- 
consin. New York, The Macmillan Com- 
pany. 1899. Pp. vi+200. Price, 90 cents. 
After a short chapter on manipulation, this 
manual is divided into two parts. Part I. is 
given to the preparation and properties of the 
elements and their compounds. The usual 
illustrative experiments are given, all of these 
being of a purely qualitative character. A few 
problems for calculation are, however, inserted. 
Part II. is devoted to the verification of quantita- 
tive laws, especially the laws of constant and 
multiple proportion, the laws of combination 
for gases, and vapor densities. Very much, of 
course, depends on the teacher, but there seems 
to be some danger that the work of many stu- 
dents with the first part of this book will degen- 
erate into merely playing with chemicals. The 
old method of preparing stannic chloride given 
on page 144 might, with advantage, be replaced 
by that of Lorenz, (Zeit. f. Anorg. Ch. 10, 44.). 
Inorganic Chemical Preparations. By FELIX 
LENGFELD, Assistant Professor of Inorganic 
Chemistry in the University of Chicago. 
New York, The Macmillan Company. 1899. 
Pp. xviii+57. Price, 60 cents. 
The study of inorganic chemical preparations 
deserves a much larger place than has usually 
been assigned to the subject in chemical courses. 
The selection of topics in Dr. Lengfeld’s book is 
excellent. Some of the directions are, perhaps, 
a little too concise for the use of students who 
have not had a good deal of laboratory experi- 
ence. Without close watching many students 
would certainly fall into serious mistakes—but, 
then, a student often learns more from a mis- 
take than by doing a thing right the first time.

SCIENTIFIC JOURNALS AND ARTICLES. 
THE American Journal of Science for Novem- 
ber contains the following articles : 
‘Types of March Weather in the United States,’ by 
O. L. Fassig. 
‘Some new Minerals from the Zinc Mines at Frank- 
lin, N. J., and Note concerning the Chemical Com- 
position of Ganomalite,’ by S. L. Penfield and C. H. 
Warren. 
‘ Action of Acetylene on the Oxides of Copper,’ by 
F. A. Gooch and DeF. Baldwin. 
“Andesites of the Aroostock Volcanic Area of 
Maine,’ by H. E. Gregory. 
“ New mode of occurrence of Ruby in North Caro- 
lina,’ by J. W. Judd and W. E. Hidden. With Crys- 
tallographic Notes by J. H. Pratt. 
The Osprey for October, makes its appearance 
under new editors and is a particularly good 
number, being very strong in interesting notes. 
The first article, ‘The Home of a Pair of Wood 
Thrushes’ is by R. W. Johnson; then follow 
‘The Butcher Bird in Florida,’ by Mrs. M. A. 
Ohlinger; ‘ Peculiar Nesting of the Hooded 
Merganser,’ by Glen Rinker; ‘ Robin Recitals 
and Variations,’ by P. M. Silloway, and ‘ Nesting 
of the Bald Eagle,’ by Wm. H. Fisher. The 
principal article, ‘Wild Guinea-Fowl of Bar- 
buda,’ by Frederick A. Ober, is in that writer’s 
best vein. L. A. Fuertes notes the occurrence 
of ‘Two Rare Warblers at Ithaca.’ In the cor- 
respondence Mr. J. Parker Norris replies to his 
critics in a letter on ‘The Utility of Large 
Series of Eggs.’ 
Appleton’s Popular Science Monthly, for No- 
vember, contains a portrait and sketch of Dr. 
George M. Sternberg, Surgeon-General, U.S. 
A. The number also contains an article on 
Cambridge University by Mr. Herbert Stotes- 
bury with portraits of Sir Michael Foster, Pro- 
fessors J. J. Thomson, G. H. Darwin, Henry 
Sidgwick and James Ward, Dr. Donald Mac- 
alister and Sir George Stokes. Other articles 
are on ‘Wireless Telegraphy,’ by Professor 
John Trowbridge; ‘Emigrant Diamonds in 
America,’ by Dr. Wm. H. Hobbs; ‘ On Spider 
Bites’ and ‘ Kissing Bugs,’ by Dr. L. O. How- 
ard, and a review of Wallace’s ‘ Wonderful 
Century,’ by Professor W. K. Brooks.
