D. Cope.’ SCIENCE is said to be edited by a 
committee consisting of ‘S. Newcomb, I. Rem- 
sen, O. C. Marsh, C. H. Merriam, J. W. Powell.’ 
There are also serious omissions, e. g., The Bul- 
letin of the American Mathematical Society and 
the Bulletin of the Torrey Botanical Club. 
The value of this compilation to the scientific 
worker is so great that the destruction by fire 
f the plates and sheets would not be regretted 
if this should lead to a new edition.

THE newly formed Harper-McClure combi- 
nation of New York City announces the publica- 
tion of an encyclopedia which is intended to 
surpass even the Encyclopedia Britannica in 
range. It is to be hoped that the scientific 
articles will be entrusted to men of science as 
competent as the writers for the Britannica. 
Messrs. D. APPLETON & Co. announce for 
early publication the ‘Comparative Physiology 
and Morphology of Animals,’ by Professor 
Joseph Le Conte, and ‘ The International Geog- 
raphy’ by Nansen, Markham, Bryce, Davis and 
others. 
Messrs. HARPER & BROTHERS have in press 
the ‘ Hlements of Physics,’ by Professors J. S. 
Ames and H. A. Rowland of the Johns Hopkins 
University.

SCIENCE. 307 
C. R. Keyes writes of the ‘American Homo- 
taxial Equivalents of the Original Permian,’ pp. 
321-842. A comparison is drawn between the 
American Permian and that of Russia as seen 
by the author during a recent Russian trip. C. 
S. Prosser follows with a paper on ‘ Correlation 
of Carboniferous Rocks of Nebraska with those 
of Kansas,’ pp. 342-357. The author deter- 
mines the relations of the Nebraska Carbonifer- 
ous with the horizons which had been previously 
established by his careful, faunal studies in Kan- 
sas. W. C. Knight, ‘The Nebraska Permian,’ 
pp. 357-375. The writer’s conclusions are that 
the Kansas Permian extends as a triangular area 
northward into Nebraska. Some tablesof fossils 
are given W. H. Hobbs, ‘The Diamond Fields of 
the Great Lakes,’ pp. 375-389. All the known 
finds of diamonds in the drift of the region of 
the Great Lakes are recorded and plotted with 
the intention of locating their probable source 
and home, and of arousing interest in the sub- 
ject. W. H. Turner, ‘Replacement Ore De- 
posits in the Sierra Nevada,’ pp. 389-401. A 
number of gold-bearing deposits in California 
are described, which are in contrast with the 
usual quartz veins and which give ground for 
an explanation by replacement. Editorials, 
reviews, and_a valuable summary of current 
North American Pre-Cambrian literature by C. 
K. Leith conclude the number. 
THE Educational Review for September opens 
with an address given by Dr. W. T. Harris be- 
fore the recent meeting of the National Educa- 
tional Association, outlining an education policy 
for our new possessions, and an article on the 
educational progress of the year by Professor 
Nicholas Murray Butler, presented to the Na- 
tional Council of Education. The number also 
contains articles on the educational system in 
Chicago, women in the public schools, English 
in Regents’ schools and the teaching of German 
in Germany.
