Ito the Annual Report for 1874-75 of the Commission for the Scien- 
tific Investigation of the German Sea at Kiel. These reports are of 
much scientific and practical value, and it would be very desirable if the 
United States Government could have similar work done in connection 
with the Coast Survey. ~ 
— Mr. Julius Stoerzer, of the National Museum at Washington, died 
on the 13th of May, aged thirty-four years, leaving a wife and child. 
Mr. Stoerzer, at the time of his death, was unquestionably the most 
thoroughly trained and really scientific taxidermist in the country. A 
pupil of the celebrated Martin, a good comparative anatomist, an enthu- 
siast in his profession ; his very skeleton frames of boards and hoop-iron 
had more life and action in them than the completed inflations we are 
generally asked to call stuffed animals. The magnificent group of fur 
seals, now at the Centennial Exhibition, is one of his masterpieces, and 
is unequaled in any part of the world so far as those animals are con- 
cerned. Mr. Stoerzer’s death is regretted by all who knew him, and it 
is felt that with him an artist as well as a preparator has passed away, 
who can hardly be replaced. 
PROCEEDINGS OF SOCIETIES. 
PuiLosornicat Society or WasHineTon.— April 22. Major J. 
W. Powell read a paper on monoclinal folds in orographic geology, tend- 
ing to show that the higher the strata were elevated above the general 
surface, the greater the proportional rapidity of their denudation or 
erosion. He also showed how by unequal elevation on two sides of a 
fault and general erosion, beds of unequal age might be brought into 
such close proximity as to lead to errors in identification. This was 
illustrated. by the case of the Green River beds, referred by Cope, 
Lesquereux, and Hayden to different horizons as a whole, from specimens 
gathered from apparently identical strata within a few hundred yards of 
each other. While each investigator had rightly referred the organic 
remains submitted to his examination to their proper horizon, the error, 
according to the speaker, had arisen from supposing that the adjoining 
and apparently identical beds were really continuous ; when, actually, 
faulting had taken place on three cross lines of fracture, with differing 
elevation and uniform erosion, thus bringing into almost exact paral- 
lelism, beds of different age. 
A discussion followed in which the question of the thickness of the 
€arth’s crust was debated. Mr: Taylor, Major Powell and others, find- 
ing it difficult to reconcile the multifarious changes of level of small 
areas with a crust of great thickness, while Captain Dutton regarded a 
Solid nucleus with a hydrothermal plastic layer between it and the outer 
Crust as ineeting the requirements of the case. -
