SUBERATS. 
Sp. 4. Suberat of Lime. 
THIS salt does not crystallize. It is perfectly white: 
it has a saltish taste : it does not redden the tincture of 
turnsole. It is very sparingly soluble in water except 
when hot ; and as the solution cools most of the salt 
precipitates again. When placed upon burning coals 
it swells up, the acid is decomposed, and there remains 
only the lime in the state of powder. 
It is decomposed by the following salts : 
1. Muriat of alumina. 
2. Carbonats of potass and soda. 
3. Fluat of magnesia. 
4. Phosphats of alumina and soda. 
5. Borat of potass. 
6. All the metallic solutions *. 
Sp. 5. Suberat of Ammonia. 
THIS salt crystallizes in parallelopipeds. Its taste is 
saltish, and it leaves an impression of bitterness. It 
reddens vegetable blues. It is very soluble in water. 
It attracts moisture from the air. When placed upon 
burning coals, it loses its water of crystallization, and 
swells up; and before the blow-pipe it evaporates en 
tirely. It is decomposed by the aluminous and mag. 
nesian salts . 
Sp. 6. Suberat of Magneria. 
THis salt is in the form of a powder : it reddens the 
tineture of turnsole. It has a bitter taste: it is soluble 
in watér, and attracts some moisture when exposed to
