PERSONAL AND SCIENTIFIC NEWS. 
The famous Clarence S. Bement collection of min- 
erals which has attracted mineralogists from all over the 
world to Philadelphia for so many years, when they wished to 
see some of the finest specimens known, has been purchased by 
the friends of the American Museum of Natural History and 
has been presented to that institution. The donors' names 
are withheld from the public at present, though this is the 
largest and most valuable single gift ever made to the museum. 
The minerals in the collection are said on good authority to 
have cost Mr. Bement not less than $150,000, while the meteor- 
ites contained in it are said to have cost an additional $50,000. 
This great acquisition places the mineral collection of the 
North American Museum on a footing comparable with that 
of the greatest collections in Europe, and the meteorite collec- 
tion is probably surpassed only by those at the British Museum 
and the Royal Museum at Vienna. The collection arrived at 
the museum during the last week of the old year, has been 
unpacked and its installation is proceeding" as rapidly as possi- 
ble. The old museum collection has been relegated to drawers 
for the present, but eventually the two are to be consolidated. 
Prof. Henry Fairchild Osborn has resigned his position 
as assistant to the president of the American Museum of Nat- 
ural History, in order to have time to attend to his new duties 
as vertebrate paleontologist to the United States Geological 
Survey. He retains, however, the curatorship of the depart- 
ment of vertebrate paleontology in the museum, and will con- 
tinue as heretofore the building up of the collection 1 he assem-
