iron contained in the substance, amounting to 12. per 100. ‘There 
will then remain 0.366 gr. of per oxide of iron on 3 gr. or 12.20 per 
100. The magnesia, precipitated by phosphate of soda and ammo- 
nia, is included in (C. : 
The solution (B), after the separation of the precipitate by the 
sub-carbonate of soda, was boiled with an excess of nitric acid, and 
on the addition of the nitrate of barytes, there was obtained a precip- 
itate of sulphate of barytes, weighing 0.535 gr. equivalent to 0.073 
gr. of sulphur, on 3 gr. or 2.433 per 100. 
After the separation of the sulphate of barytes, the excess of acid 
was neutralized with ammonia, and after the addition of more nitrate 
of barytes, no chromate of barytes was precipitated, notwithstanding 
the liquor had a yellow hue. It was also ascertained that the precip, 
itated sulphate was free from chrome. 
According to the precedent results, the constituents of this mete- 
os are—

4.069 Loss and Hygrometrical Moist- 
The above loss is somewhat considerable, but the principal Te 
sults having been verified approximately by different trials, the pre- 
cedent analysis is deemed sufficiently accurate, to shew the close 
analogy between this and other aérolites.
