   note: in the chemical nomenclature adopted by guyton de
         morveau, lavoisier, and their associates, the term
         oxides was made to include all compounds of oxygen
         which had no acid f. acide properties, as contrasted
         with the acids, all of which were at that time supposed
         to contain oxygen. the orthography oxyde, oxyd,
         etc., was afterwards introduced in ignorance or
         disregard of the true etymology, but these forms are
         now obsolete in english. the spelling oxid is not
         common.
