Note. This table does not comprehend the earthy and metal- 
lic salts which have constantly an excess of acid, because their 
decomposition may be easily foreseen. MM. Thenard and 
Hoard have had an opportunity of particularly observing it in 
alum, in their interesting work upon mordants. (Annales 
de Chernies, tome LXXIV, p. 279.) 
Before I proceed to the consequences that may be deduced 
from the observations noted in this table, I shall make some re- 
marks upon several of them. 
All those salts which have ammonia as their base, are com- 
pletely decomposed by the insoluble carbonates found in the 
same column, the new insoluble salt replaces the carbonate 
which is decomposed, and the carbonate of ammonia becomes 
disengaged as it is formed ; so that if a sufficient quantity of 
insoluble carbonate be added^ nothing will remain in solu- 
tion. '
