J. L. Smith—Description of Meteoric Stones. 223 
some specimens are in the cabinet of Yale College, and others 
scattered about among the inhabitants of the country where it 
fell. 
As regards its temperature at the time of falling I would say 
that I have a specimen, which gives as it were a satisfactory 
record that it was not very hot when it struck the tree, for a 
portion of the fibers of one of the branches is adhering to the 
surface entangled in the rough crust of the stone, and these del- 
icate fibers show not the slightest signs of having been heated. 
A fact to be noted in connection with the fall of this meteorite 
its rapid motion through the atmosphere, and dropped quietly 
like an exhausted bird in its flight. Its direction, so far as 
made out, was from northwest to southeast. 
Aspect of the Stone.—Studied by the various fragments that are 
under my observation, it differs in a marked degree, although 
pisolitic, from the one just described, and which fell only 
a few days previously. It has its own points of peculiar inter- 
est, and is not like any meteorite that I am familiar with, ex- 
cept the Ornans meteorite, which fell July 11th, 1868; and this 
it resembles closely in every particular, as may be seen by com- 
paring my results with those of Pisani (Comptes Rendus Acad. 
Sci., 1868, vol. ti, p. 668), although his method of recording the 
analytical results is different from mine, and the specific gravity, 
as made out by him, is higher than mine, which is not singular 
in different specimens of these porous bodies. Its crust is dull _ 
black, and quite thick; in many places, of several centimeters 
square, from two and one half to three and one half millimeters 
thick (the thickest I have ever seen), where the crust is a 
rough scoria that sometimes terminates abruptly on a smooth 
portion of the crust, and is doubtless produced by the melted 
matter on the surface being forced backward and opposite to 
the direction of the flight of the stone, being swept off one por- 
tion of the surface, and leaving this part smooth, and piled up 
behind it, in the form of a surface of scoria. 
The interior of the stone has a very dark uniform ash color, 
and is soft and easily crushed; the latter fact accounts for its 
having broken into fragments as it struck the ground. Its spe- 
cific gravity is 8-47, and the amount of metallic matter con- 
tained in it is small. 
Chemical composition.—The stone pulverized and freed from 
metallic particles gave on analysis an amount of sulphur equal 
to 3°51 per cent of troilite; the amount of nickeliferous iron 
was small, being equal to 2°01 per cent. The stony minerals 
treated with chlorhydric acid gave—
