Meteoric Iron of Texas and Lockport. 373 
The hydrochloric solution’ (A) afforded no precipitate when 
treated with sulphuretted hydrogen; and the iron being thrown 
down from a portion of it by ammonia, the filtrate bow f examin- 
ed in vain for cobalt, manganese and zinc. 
The insoluble black powder (B), when digested in aqua regia, 
_ Was partly dissolved, while another portion remained, consisting 
of flakes of graphite, or at least of a very incombustible carbon 
containing a little iron. Sulphuretted hydrogen passed through 
the solution gave a yellowish brown precipitate, which was dis- 
solved by hydrosulphuret of ammonia (C), leaving only a trace 
of sulphuret of copper. The soluble portion (C) was precipita- 
ted by acetic acid, and its color appeared to be orange, but was 
‘Somewhat obscured by free sulphur. 'The results obtained from 
its examination were anomalous and rather unsatisfactory. It 
fused with nitre and carbonate of soda, forming a mass which was 
Soluble in water without residue, and whose solution nitric acid 
did not sensibly affect. ‘Treated with nitrate of silver and a dilute 
solution of ammonia, with reference to the detection of arsenic 
acid, it gave a white precipitate in place of the red-brown of the 
arseniate of silver. A part of the solution was treated with 
acetate of lead, and the precipitate obtained, when reduced before
