opinion that the one or the other should alone be employed, and 
that the substance used as a cement should partake of the nature 
of the solid material, that thus the whole mass may more nearly 
resemble a uniform structure. In this connection arises the ques- 
tion as to the proper finish of the internal face of such wall, this 
being the surface presented to the sound.

Arr. XL.—WNotice of the Meteoric Iron found near Seneca River, 
_ Cayuga County, N. Y.; by Cuartes Upuam Sueparp, M.D. 
| Tus iron was very briefly announced in the November num- 
ber of this Journal (vol. xiv, p. 439,) by Prof. O. Root of Hamil- 
ton College, Clinton, N. Y. The weight of the mass was be- 
tween eight and ten pounds. It was picked up by a farmer, 
while engaged in excavating a ditch; his attention having been 
arrested by its unusual weight, as compared with ordinary stones. 
A thick coating of limonite (hydrous oxyd of iron) formed the 
entire outside of the mass. Its general figure was somewhat 
drop-shape ; although the customary depressions found on the 
) ‘Surfaces of meteorites, were visible also, in the present instance. 
Tam indebted to Prof. Root for a very perfect tetrahedral frag- 
Ment (of about two ounces weight) which must have formed the 
little end of the meteor; and to Le- 
y C. Partridge, ., of Seneca 
Palls for a thick slice (of four and a 
ounces) which apparently, is a 
“ction across the mass, next below 
the above.

bubbles of nearly pure hydrogen gas.
