In the ounce of boiling water that had been filtered from 
thib refiduum, I could find nothing but feme minute particles 
of that fubftance and veftiges of iron. Two or three drops of 
the liquor, N° i. added to three ounces of diftilled water, pro- 
duced a pietty confiderable milkinefs ; and, on ftanding, a 
cloie white fediment was depofited. Two or three drops of 
the liquoi, N 2. produced lefs milkinefs and fediment in the 
quantity of water juft mentioned than N° 1. N° 3. fcarcely 
dimimfhed the tranfparency of diftilled water ; and N° 4. did 
not affect it all. The liquids, N° 3. and 4. were diftilled till 
there remained about two drachm- meafu res of clear brown 
liquid, with a cloudy fediment. N° 3, being poured into two 
ounces of diftilled water fcarcely made it milky ; and N° 
4. did not diminifh the tranfparency of water at all. On 
evaporating to drynefs thefe mixtures of the liquors, N° 3. 
and 4. with diftilled water; that with N° 3. left a yellowifh 
dry fediment which weighed 3, r grains ; and that of N° 4. left 
2,2 grains of fediment. Nothing but calx of antimony could 
be dilcovered in thefe fediments. They were reducible readily 
witn tartai ; fcarcely fufible in the fpoon ; but with phofphoric 
acid eafily melted into an opaque yellowifh globule. 
The liquor, marked N J 1. being poured into tw T enty-four 
ounces of diftilled water produced a very milky appearance ; 
and the fame appearance, but in a much lefs degree, enfued 
011 pouring the liquor N 2. into this quantity of pure water. 
After ftanding feveral days, a white fediment being depofited 
fiom a clear watery fluid, the clear liquid was drawn off by 
means of a fiphon, and the fediments being dried, that of 
N° 1. weighed 51 grains ; that of N° 2. weighed 6,15 grains; 
and both were found to be purely Algaroth powder. The wa- 
t^r 3 viz, 4 > ounces, in which thefe precipitates fell, being 
evaporated
