240 F’. A. Genth on a Meteorite from New Mezico. 
In analysis II, the meteorite was dissolved in diluted nitric 
acid, and the residue filtered off on a weighed filter. In the filtrate 
iron was separated from cobalt and nickel, by addition of a suffi- 
cient quantity of acetate of potash, in order to convert the nitrates 
into acetates, and evaporation to dryness in a water-bath. The 
dry mass was boiled with water and filtered. From the filtrate, 
which contained the whole quantity of oxyds of cobalt and 
nickel, these were precipitated by caustic potash. The precipi- 
tate of sesquioxyd of iron was re-dissolved in hydrochlorid acid, 
and precipitated by ammonia. his method gives excellent 
results, if used with care. The only objection might be, that the 
sesquioxyd of iron, thus separated, is difficult to filter 
The insoluble residue was ignited and fused with bisulphate of 
potash. On treating the fused mass with water, a white substance 
of the appearance of tartaric acid remained, which bydrochlori¢e 
acid slowly dissolved. This substance and sesquioxyd of iron 
were precipitated by ammonia, and from the filtrate, oxyd of 
nickel separated as usual. The precipitate was weighed, dissolv- 
ed in hydrochloric acid, and the iron precipitated by sulphid of 
ammonium, after the addition of tartaric acid and ammonia. 
From the sulphid of iron, the iron was determined as usual. 
From the filtrate, the other substance remained after the tartar 
acid was destroyed by heat. It was, however, a very small quan 
tity, and only sufficient for one blowpipe reaction. The borax 
bead gave in the inner flame an enamel of a bluish color. 
therefore believe that it is tartaric acid, though the reactions 
somewhat differ. 
The insoluble residue seems to be a combination of Iron, 
Nickel and Titanium. It contains no cobalt. Neither patt of 
the meteorite contained carbon, sulphur, phosphorus or tn.
