Chap. III. 
Sp. 17. Benzoat of Antimony. 
BENzoIc ACID readily dissolves the oxide of anti 
mony, and the solution yields crystals, which remain 
dry when exposed to the air, and are decomposed by 
heat *. 
Sp. 13. Sebat of Antimony. 
SEBACIC ACID dissolves the oxide of antimony by 
the assistance of heat, and forms a salt in small crystals, 
which do not deliquesce in the air f. 
GENUS XIII. SALTS OF TELLURIVM. 
TELLURIUM has been known for so short a time as 
a distinct metal, and the quantity of it hitherto exa 
mined has been so small, that the salts which it forms 
with acids cannot be supposed to be much known. 
Only the following facts have been ascertained. 
The salts of tellurium may be distinguished by the 
following properties : 
1. Alkalies, when dropt into their solution, occasion Characters 
a white precipitate, which disappears again if the alkali 
be added in excess. 
2. Triple prussiat of potass occasions no précipitate. 
3. Hydrosulphuret of potass occasions a brown or 
blackish precipitate. 
4. The infusion of nutgalls occasions a flaky preci 
pitate of a yellow colour. 
5. Zinc, iron, and antimony, when plunged into 
these solutions, occasion the tellurium to separate in the
