test for — or phosphorus; the quantity of iron separated 
om the stone did not warrant my m aking special analyses for 
substances, a quantity of which present could only be exceed- 
ingly minute. 
The stony matter freed from the iron was treated with nitro- — 
muriatie acid and water, and heated for some time over a water 
bath, renewing the water and acid once or twice; the solution 
was fi tered, and the residue washed; the residue was then 
to gies over a water bath, es gently over the lamp, 
and treated with water and a little hydrochloric acid, thrown 
on a filter, the silica collected and estimated; the last filtrate 
was treated with a solution of hydrochlorate of baryta to 
ascertain the quantity of sulphuric acid present, (due to the 
pyrites in the original mass) ; it was found to indicate 6-10 per 
cent of magnetic iron pyrites. e solution freed from the 
excess of baryta was now analyzed in the ordinary way. 
The insoluble Ngee: os the meteorite was fused with car- 
bonate of soda and a small fragment of caustic potash, and its

rate portion of the stony part of the meteorite was 
exainined as alkalies.
