comes sufficiently obvious on bringing it near the eye, when it 
appears to be composed Prncipaly of a bluish grey SUDSt BRS 
in globular masses, from the size of a mustard seed to t 
a pea, and a white, ede cohering mineral: the formas in 
much the largest proportion. ter these, on closer inspec- 
tion, are visible minute hook shaped, and sometimes slightly 
flattened globular masses of a metallic nature, whic 
ten partially coated by rust, and minute steel grey grains — 
and crystals, which for the most part occupy the cavities be- 
fore mentioned, and are sometimes arranged so as to resem- 
e the characters used in the paren languages. Besides 
peony by the aid of a microscope, we discover occasionally a 
greenish transparent Saranated substan, and more rarely 
lites, Like these, the two substances of which it is chiefly 
omposed are in masses sufficiently large to appear quite dis- 
bint to the naked eye, although from the description already 
given, it will be perceived that it differs considerably even 
from them, by its numerous cavities and their crystallized 
cantons, _ It differs wey essentiaily from the Maryland

it requiring a pretty smart blow of the hammer to produce a 
acture, and the small masses ta to separate by the mere 
strength of the fingers.. Its specific gravity, as determined 
in two fragments, one weighing 82°3 grs. and the other 38-5 
was 3°29, and 3°31. 
After these observations upon the general character of the 
specimen under examinat ‘ion, I proceed to the separate de- 
scription of the minerals it contains.

ae gen shaped bodies which compose the chief 
‘part of the Virginia aerolite are thus denominated, because 
in their eaaralrancal characters, they approach very clos ely 
our species crysolite. I offer the following description of its 
haracters.
