THE PHOSPHORESCENCE OF THE DIAMOND AFTER EXPOSURE TO 
SUNLIGHT, AND ALSO BY FRICTION. 
Only blue-white diamonds possess the property of emitting light 
after exposure to sunlight, but all diamonds, when rubbed in the 
dark on a rough board, tile,. metal, leather, or cloth, phosphor- 
esce in different degrees of intensity, resembling the light pro- 
duced by the glow-worm or a phosphorus match. The stones 
that emit light after exposure to sunlight show this to a much 
greater degree. Dr. Robert Boyle virtually announced all these 
facts about the diamond more than two hundred and thirty years 
ago. 
A paper describing the two meteorites (one of one hundred 
and eighty and one of ten pounds) from Washington County, 
Kansas, and a thirty-pound meteoric iron from Floyd County, 
Virginia, will be published later on. 
Mr. GitmMAn S. STANTON read a paper on 
THE OCCURRENCE OF BERYLS AND GARNETS ON NEW YORK 
ISLAND. 
(Abstract. ) 
I have been requested to exhibit to the Academy some beryls 
and garnets which I obtained from a vein at 65th street and 
Ninth, or Columbus, avenue of this city. A number of the 
members of the Mineralogical Club know of this vein, but, as it 
has recently yielded some large beryls, perhaps a short descrip- 
tion of it would be of interest. 
Nearly three years ago I first discovered that this vein con- 
tained a remarkable quantity of interesting, beautiful, and ex- 
ceedingly perfect crystals of garnet. For about a month, while 
the blasting continued, I succeeded in getting a large number of 
specimens, ‘The vein, which was of a coarse granite, cut a light- 
colored variety of the gneiss of this city and averaged some
