Analysis of the Tennessee Meteorite. 



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.) 



G. 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 resuhs, the constituents of this mete- 

 orite are —

The above loss is somewhat considerable, but the principal re- 

 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 aerolites.
