COMBINATIONS OF WATER. i 
Before dismissing the subject of the nomenclature of the oxysalts 
it is proper to say a few words respecting the compounds into which — 
water enters. Water has been considered as playing the part of an 
acid in its combinations with bases; which have “hence been called 
hydrates. Thus we have potassic hydrate, calcic, ferric, &c. hydrates. 
But water combines also with acids, and in these compounds corres- 
ponds to a base. We should therefore use the terms hydric sul- 
phate, hydric nitrate, hydric Phosphate, &c. It would be quite as 
difficult to become habituated to the use of the term hydric sulphate, 
for common sulphuric acid, as to that of hydric oxide or hydric acid, 
for water. Some chemists call the acids which contain water, hy- 
drated acids. Such a denomination is contrary to the principles of 
nomenclature. I shall call an acid, in which water acts as a base, 
an aqueous acid, and one where there is only a mixture of acid and 
water a dilute acid. As acids more frequently contain water than 
the reverse, it will be more convenient to express that the acid con-
