sion of dark-colored glass, bronzite in broken fragments and also 
in spherules with a fine fibrous structure, broken plagioclase, 
rich in black inclusions lying parallel to the twining planes 
and, finally, patches of an isotropic mineral, probably maskelyn- 
ite. It contains the following constituents: nickeliferous iron, 
17.16 per cent.; mineral portion, 82.84 per cent. The iron 
yielded upon analysis, Pes o1.42 per cent. ; Nee Sod: Co 
0.60; Cu=o.04. The mineral portion was divided e two 
parts, one soluble in hydrochloric acid yielded, FeS = 6.08; NiS 
= 0.62; and 48.85 per cent. silicates; the other, pusetuble in | 
this acid, gave, chromite 0.75, and 43.22 per cent. silicates. A 
second meteorite, from Cape Girardeau, Missouri, proved, upon 
examination, to belong to the same general class as the one last 
mentioned. catalogue of the meteoric stones in the col- 
lection of Yale College, one hundred and forty-seven in number, 
is published as an appendix in the same number of this journal. 
Perhaps the most important paper on meteorites which 
_has appeared during the year is that of Reusch.* In this are de- 
scribed four Scandinavian meteorites, each of which presents in- _ 
teresting features. The most noteworthy of these is the occurrence 
of olivine in forms imitative of organic structures, and also, to- 
gether with bronzite, forming spherulitic bodies in a ground-mass 
composed of crystals of bronzite, augite, and iron in a glassy base. 
he most instructive fact in this connection is the discovery of a 
brecciated structure in two of the meteors described. The rounder 
grains which occur in the crystalline ground-mass surrounding 
them are of the same nature as this ground-mass, and are in turn 
composed of other smaller grains of similar mineralogical com- 
position. A gradual transition from the large fragmental parti- 
cles to the “ chondra” was traced, and from this fact, in connection | 
with the others above mentioned, the author draws certain gen- 
eral conclusions in regard to the origin of meteoric bodies, which, 
although exceedingly interesting, it would be oe to in-
