In the saponification by bases it has been found that all strong bases exert about the same action. The velocity of

��reaction at 9-4° is 2-29 !

The numbers are for ^^o-normal solutions, in which the strong bases may be regarded as completely dissociated; in equivalent quantity they should exert the same action, which, according to the above numbers of Reicher (J^O), they actually do. The corresponding value for the weakly dissociated ammonia is 0011.

Objections to the Assumption of Electrolytic Dis- sociation. — However it may be with some details not yet
