Note 637 — PHARMACOLOGIA. (continued 7)

This term is also applied to the Sub-carbonate of Ammonia. The objection to its use depends upon the solecism which it involves; the division of an atom, which, according to chemical principles, is indivisible; but this objection may be answered by stating, that the term is one merely of convenience, and serves to express the proportions of the acid and its base. The chemical difficulty is at once solved by multiplying each by two, which will make the proportions as 3 to 2. instead of 1½ to 1.
