PERSONAL AND SCIENTIFIC NEWS. 
Dr. a. S. Eakle, instructor in petrography at Har- 
vard University, has gone to the University of California. 
Professor C. R. Van Hise and J. Morgan Clements 
spent July and August in a study of the pre-Cambrian 
geology of the north shore of lake Superior. 
Mr. Frank Leverett and Mr. F. B. Taylor are en- 
gaged on the glacial geology of the southern peninsula of 
Michigan for the United States Geological Survey, in the 
region of Saginaw bay and southwestward. 
Mr. S. Ward Loper, curator of the Museum of Wes- 
leyan University, has gone to Cape Breton island under the 
auspices of the U. S. Geological Survey to study the pre- 
Cambrian geological formations discovered by Dr. F. S. 
Matthew. [Science.) 
Prof. Henry F. Osborn returned from Europe 6 Sep- 
tember. He attended the International Geological Con- 
gress, of which he was elected one of the American vice- 
presidents, and the Exposition, but spent most of his time 
studying the fossil mammals, especially rhinoceroses in the 
museums of Paris and London. 
Dr. John M. Clarke and Mr. Charles Schuchert 
have recently visited Nova Scotia for an examination of the 
fossiliferous Silurian rocks of Arisaig, which seem to consti- 
tute a unique development of Silurian strata in North Amer- 
ica much more akin to the Silurian of Great Britain than to 
that of the St. Lawrence valley of New York state or the 
province of Ontario. 
At the Late Meeting of the American Association 
for the Advancement of Science a committee consisting of 
John M. Clarke, W J McGee, J. McK Cattell, Chas'. H. 
Hitchcock and Theo. Gill, was appointed to report on the 
erection of a bronze tablet to mark the house in Albany 
where the geologists of New York in 1838 met to make ar- 
rangements for the Association of American Geologists, 
the parent body of the American Association for the Ad- 
vancement of Science. {Science.) 
At the Same Meeting Dr, Erasmus Haworth de- 
scribed the recent discovery of native copper in Garfield 
county, Oklahoma. It is found in the "red beds" of Cre- 
taceous age, in a clayey shale, in the form of thin circular 
discs about an inch in diameter, which do not lie in con- 
cordance with the stratification of the bed, but were in- 
troduced by some later chemical reaction from solution.
