But it has been pointed out that certain of the silver compounds are isomorphous with the corresponding sodium and potassium compounds, and as there is no reason to suppose that the argentic compounds generally are not of similar constitution to argentic chloride, the conclusion that there are two atoms of silver in the molecule of argentie chloride would appear to necessitate the assumption that the compounds of the alkali metals also contain at least two atoms of the metal in their molecules ;-that the formula of sodium nitrate, for example, is Na2(NO3)2, and not NaNO3. The existence of a compound of sodium ethyl with zinc ethyl, NaZn(C,II,),, from which the former cannot even be separated, appears to show that sodium does not invariably function as a monad.
Speculations of this kind are extremely hazardous, but, as no method is known enabling us to ascertain the molecular composition of compounds which cannot be volatilized, they possess a certain interest and, moreover, point to the necessity of investigation in this direction.
