instruction in geology at tlie Johns Hopkins Universit}^ have 
been somewhat changed. The department of geology is now 
under the direction of Dr. Wm. B. Clark, Profes-'sor of Organic 
(reology, assisted b}" Dr. E. B. Mathews, Instructor in Miner- 
alog^T^ and Petrography. In addition to the instruction given 
by these two gentlemen, Mr. G. K. Gilbert and Mr. Bailey 
Willis, both of the United States Geological Surve}^ will give 
courses of lectures on physiographic geology and on strati- 
graphic and structural geology respectively.

The seventh annual meeting of the Geological Society of 
America was held, under the presidency of Prof. T. C. Cham- 
berlin, in the geological laboratory of the Johns Hopkins 
Universit}'', Baltimore, Md., from Tinirsday to Saturday, De- 
cember 27th to the 29th. Sixty or nuire fellows of the societ}' 
were in attendance, and fifty papers were presented. Pres. 
D. C. Gilnian, speaking in behalf of the university and city, 
gave a cordial address of welcome. In selecting Baltimore as 
the place for its winter meeting, the society had counted es- 
pecially on the presence of Prof. George H. Williams of this 
universit}', the second vice-president of the society, as one of 
those extending to it greetings and hospitality; but his la- 
mented death last summer left to his associate, Prof. William 
B. Clark, double duty on the local committee and the pre- 
sentation of an address in memorial of Prof. Williams. A 
memorial of Mr. Amos Bowman was also given by H. M. Ami. 
Three other societies of national extent also held meetings 
at the same time at the Johns Hopkins University, namel}^ 
the American Society of Naturalists, the American Morpho- 
logical Society, and the American Physiological Society. 
Many attiliated workers in all departjiients of the natural 
sciences, convening from widely different parts of the coun- 
try, were thus afforded opportunities for most pleasant re- 
newals of old acquaintance; and the several meetings, occu- 
pying dift'erent rooms of the university at the same time, 
reminded one of the yet nuire numerous sections in the annual 
summer meetings of the American Association. During a 
part of Friday the Geological Society, on account of its large 
number of papers, met in two sections, peti-ographlc papers 
being read in one section, and glacial pajjers in the other. 
Professor Ghamberlin, in his address Friday evening as the 
retiring president, spoke of his observations during the past 
summer on the glaciers and ice-sheet of Greenland, especially 
of Inglefield gulf and of Bowdoin bay, a fjord extending from 
that gulf northward to Lieut. Peary's winter station. A series 
of very instructive lantern views of these glaciers was exhib- 
ited after the address, of which, and of the other glacial and
