    from each acid. These radicals replace one atom of hydrogen in the single molecule of ammonia just as the monad radicals of dibasic acids do, and monamides are formed; but these monamides are amic acids if the radical so introduced contain the replaceable atom of hydrogen, or neutral amides if it contain only the non-replaceable atom. Thus from glycollic acid we have; Glycollamic Acid Methyl Glycollamate (Glycocin.) Potassium Glycollamate. (Sarcosin.) CM.O HO) CM.O KO) aH,0 CH3O) H VN. H -N. H VN. hJ hJ hJ and also; Glvcollamide.

The following for- mulae describes it. CfiH.oO HO) H VN. Hj In other cases a second of the atoms of the hy- drogen in ammonia is replaced by an acid radical. Thus hippttric acid only differs from glycocin by having one hydrogen atom replaced by the radical of benzoic acid. QH,0 HO' C,HjO H j In.
