The stilus laryticus is slightly soluble in water and does of barites* 
not change by the action of the air. If a boiling solution of 
stibiite of potash be let fallen drop by drop into a boiling solu- 
tion of muriate of barites, the stibiite of barites crystallizes 
gradually on the tube, in the form of small white needles of a 
silky brilliancy. 
The stilus kalicus forms a crystalline powder, 'which is 
white and very little soluble in water. 
The stilus plumbicus perfectly resembles a stibiiate of the !ea( | 
same base. The stilus manganosus, ferrosus and zincicus like- 
wise resembles the stibiate, with the same bases, but they are 
rather more soluble in water. 
The stibiis cobalticus is considerably soluble in water. It 0 f cobalt, 
precipitates in the form of a voluminous lilac powder, inclined 
to red, and does not assume the smallest appearance of crystalliza- 
tion by drying. When heated, it loses one fourth of its 
weight in water of crystallization, and becomes greenish grey. 
If a neutral solution of cobalt be precipitated by a stibiate of 
potash, which contains potash in excess, a violet precipitate is 
formed, which is still more soluble than the former, and appears 
to be a substibiis cobalticus. 
Stibiis cupricus is a powder of a very pale greenish blue, 0 f CO pper. 
perfectly insoluble in water. When heated it loses its water of 
combination and becomes green. A stibiite of potash, with 
excess of the latter precipitates the salts of copper of an apple 
green, resembling the arsen be of c pper (Scheele’s green.) In 
the fire it becomes black, and when pulverized it assumes a 
yellowish grey. It appears to be a substibiis cupricus.

the saline combinations formed by these two acids greatly and can act a* 
resemble each other, in the like manner as it has been long 
proved in chemistry, that there are arseniates and arsenides. 
Antimony also has the analogy with sulphur, of producing a 
salifiable base, which combines with the muriatic acid, but 
which is easily separated by water, with which the acid com- 
bines in preference, as it is a more powerful base than thos* 
| oxides.
