however, the uprise of the land seems to have ceased or to have been 
very slow for at leasi L50.yoars, as shown by inscriptions cut on a pre- 
cipitous rock shore there by sailors as early as 1741, 1740, 175:5 and on-

PERSONAL AND SCIENTIFIC NEWS. 
Prof. Charles S. Prosser, of Washington college, Kansas, 
has been appointed to the chair of geology at Union college.

Gen. William W. Duffield, of Detroit, has been appointed 
by the president to succeed Prof. T. C. Mendenhall, resigned, 
as superintendent of the U. S. Coast and Geodetic Survey.

the Geological Survey of India, is appointed to succeed Dr. 
William King as director of that survey. 
The Constantinople earthquake of July 10, 1894, trans- 
mitted its earth pulsations as far westward as to Kew, 
England. An investigation of their velocity by Prof. Charles 
Davison (in Nature for Sept. 6) shows that this distance of 
2,500 kilometers was traversed in 780 seconds, at the average 
rate of 3.23 kilometers, or about two miles, per second. To 
Utrecht, in Holland, nearly 2,200 kilometers, the rate of 
progress of this earth wave per second was 4.05 kilometers, or 
two and a half miles. In general the progress to nearer points 
was not more rapid proportionally than for these greater dis- 
tances. The speed of transmission of the earthquake at 
( liarleston, S. G, August 31, 1886, felt 800 to 900 miles north 
and northwest in New England, New York, Wisconsin, and 
Iowa, was found by Dutton to be about three miles per sec- 
ond. 
The geological map of Europe, which has been under 
course of preparation by a committee of the International 
Congress of Geologists since 1881, contains 4-9 sheets, of which 
six are now ready for issue, including Scandinavia, northern 
Germany, and parts of France, Belgium and Poland. It is 
expected that the next ten sheets will be issued within a year, 
to include the British Isles, France, Spain and Portugal, Italy, 
and Switzerland. In the drift-covered area of northern and 
northwestern Europe, the bed-rocks, where their distribution 
is known, will be shown by thin bands of color over the colors 
for the Quaternary formations. The subscription price for 
the entire map is $20, but this may be paid in instalments 
as the successive parts are issued, the proportion for the first 
part being $2.50. Subscriptions must be sent to Dietrich 
Reimer, Berlin, before the close of this j^ear, after which the 
price will be increased. — Nature, Sept. 20.
