This is evidently olivine, with a small amount of sulphide of 
iron, which is so disseminated through the stone that it is not 
easily separated completely by mechanical means. From the 
mineralogical examination and the chemical results detailed 
above, this meteoric stone consists essentially of nickeliferous 
iron, bronzite and olivine, with small particles of anorthite and 
enstatite. Its composition is, therefore, a usual one. 
For particulars in regard to the fall of this meteomte I am 
indebted to Prof. Kerr, State Geologist of North Carolina.

and 1°5 grams Rochelle salt is added, producing a crystalline pre- 
cipitate. After standing an hour, the precipitate is filtered off; 
the filtrate should not show the slightest turbidity on adding a 
drop of ammonia. The production of a precipitate indicates the 
presence of cinchonine or quinidine. These may be distinguished 
monia is added. No precipitate is produced if cinchonine be ab- 
sent.— Liebig’s Annalen, obrevi: $25, May, 1875. G. F. B.
