through it. The two minerals are mixed under various forms; 
sometimes the green mineral is in small rounded particles 
intimately mingled with the gray, at other times it is in small 
cavities in minute crystalline fragments, without any distinct 
faces, and almost colorless. The masses are quite heavy and | 
vary much in specific gravity in their different parts; but the 
average cannot be less than 4°5. en, broken, one is imme- 
diately struck with the large nodules of metal among the gray 
and green stony substances, some of which will weigh 100 grams 
ormore, In this respect this meteorite is unique, it differing 
entirely from the mixed meteorites of Pallas, Atacama, ete., or 
the known meteoric stones rich in iron; for in none of these 
has the iron this nodular character. 
Another striking feature in the relation of the iron and 
stony matter is, that the larger nodules of iron appear to have 
Not any iron nodules, and where the minerals appear more 
crystalline, indicating an irregular shrinkage during the con- 
solidation. 
That the stony part of this meteorite consists essentially of 
bronzite and olivine will be seen from the chemical investiga- 
tion, which found only three essential constituents, viz: silica, 
ferrous oxides and magnesia. Another silicate will be refer- 
red to beyond, consisting of the same oxides, but in different 
proportions from either bronzite or olivine.

as far as possible from metallic iron by the aid of the magnet, 
when treated with chlorhydric acid on a water bath for several 
ours, is resolved into soluble and insoluble parts, the propor-
