Mr. Georce F. Kunz exhibited a unique specimen of asteri- 
ated blue sapphire, from Ceylon, from the cabinet of the late Mr.

pyramid, about two inches long, and an inch wide across the base, 
which latter is polished and displays a very beautiful asterism The 
color is a fine blue, though not transparent. Also a pink-tinted 
apophyllite, from the new tunnel through the Bergen Hill.

erals : 
Calc Spar. This in its first form is very abundant, in quite pure and 
perfect crystals, often with a fine yellow tinge, but seldom transparent : 
the variety known as dog-tooth spar has been found in excellent con- 
dition, but only in limited quantity. 
It seems peculiar to this mineral here to occur in vertical veins in 
the trap, while most of the other species occur in beds more or less 
horizontal: thus showing most of the calcite here to have crystallized 
from inflowing water, filling up the fissures produced by various causes. 
Very little of it was found in cavities in the trap, as this does not seem 
to be amygdaloidal here. A few almost perfect geodes and druses 
of so called nailhead spar have been observed, mixed with the dog- 
tooth spar,
