SCIENTIFIC JOURNALS AND ARTICLES. 
The Journal of Geology for July—August con- 
tains the following articles : 
‘A new Analcite Rock from Lake Superior,’ 
by A. P. Coleman. On the north shore of Lake 
Superior in the vicinity of Heron Bay, Dr. 
Coleman recently discovered a series of dikes, 
one of which proved to be an analcite rock. It 
has some peculiarities of texture, contains about 
52 per cent. silica, and is related to basic 
syenites. The name Heroniteissuggested. A 
complete analysis is given. 
‘ Corundiferous Nepheline Syenite from East- 
ern Ontario,’ by A. P. Coleman. Dr. Coleman 
gives some additional notes and facts about 
this peculiar rock. 
“The Effect of Sea-Barriers upon Ultimate 
Drainage,’ by J. F. Newsom. This very interest- 
ing and suggestive paper shows how the barrier 
beaches and their attendant sounds may, when 
the coast line is elevated, cause the main artery 
of the resulting drainage to run parallel with 
them, and at right angles to the subordinate 
tributaries. 
‘Season and Time-elements in Sand-plain . 
formation,’ by Myron L. Fuller. From a close 
study and very ingenious interpretation of the 
Barrington sand-plain and its attendant clays, 
on Narragansett Bay, R. I., and with auxiliary 
inferences about the effects of the seasons on the 
discharge of a glacier, the author makes a com- 
putation of the time required to yield the ob- 
SCIENCE. 775 
served phenomena. The results check up very 
well with general criteria, and the paper is an 
interesting attempt to give quantitative defini- 
tion to otherwise hazy themes. 
‘ Petrographical Province of Essex Co., Mass,’ 
VI., ‘General Discussion and Conclusions,’ by 
H.S. Washington. In this the concluding instal- 
ment of the series of papers contributed by Dr. 
Washington to recent numbers of the Journal of 
Geology, the author generalizes regarding the 
peculiar chemical features and mineralogy of 
the Essex County rocks. Healso discusses their 
bearings on the general question of magmatic 
differentiation. Dr. Washington concludes that 
differentiation occurred and that it was lacco- 
lithic rather than abysmal. 
‘A Peculiar Devonian Deposit in Northeastern 
Illinois,’ by Stuart Weller. <A small triangular 
mass of rock containing Devonian fossils has 
been uncovered in a quarry of Niagara lime- 
stone at Elmhurst, Ill. It appears to have been 
a hole in the limestone when the latter formed 
the sea bottom in Devonian time,.and to have 
been a resort of fish whose remains have been 
preserved. 
‘Descriptions of New Species of Diplodus 
teeth from the Devonian of Northeastern Illi- 
nois,’ by C. R. Eastman. The paper describes 
the fish, the discovery of whose remains is de- 
tailed in the previous paper. 
‘Dipterus in the American Middle Devonian,’ 
by J.S. Udden. This short paper describes and 
figures a Dipterus tooth recently found in the 
limestones at Fairport, Muscatine Co., Lowa. 
Under the ‘Studies for Students,’ Stuart 
Weller gives an excellent sketch of a ‘Century’s 
Progress in Paleontology.’ 
The number closes with editorials and re- 
views. 
THE October number of the Bulletin of the 
American Mathematical Society contains a Report 
of the recent Summer Meeting of the Society, 
by the Acting Secretary, Professor Thomas F. 
Holgate ; the ‘ Report on the Recent Progress in 
the Theory of Linear Groups,’ presented before 
Section A, of the American Association, at the 
Columbus Meeting, by Professor L. E. Dickson; 
several ‘Shorter Notices’; ‘ Notes’; and ‘New 
Publications.’
