J. L. Smith—Dickson County Meteorite. 351 
This iron is not absolutely compact, for one can trace, even 
with the eye, minute cavities which are distinctly visible with 
a lens; but I have not yet been able to detect any schreibersite 
either on the surface or in the interior of the mass. 
Its specific gravity is 7-717. 
On analysis it was found to consist of

No trace of sulphur was detected, and so minute a trace of 
phosphorus, that only a few exceedingly small crystals of 
- phosphate of magnesia and ammonia could be discovered in the 
test made with a gram of the iron, representing only a small 
tion of a milligram of phosphorus. In fact, I have never 
yet analyzed a meteoric iron containing so little phosphorus.
