colic acid, its formation is represented by the equation. 
CisHsNOc+NOs=Ci sHsOs+HO-+-2N. 
boiled with water containing a small quantity of sulphuric acid, it is e- 
composed into benzoic acid, and a new acid homologous with lactic acid 
and which the authors term glycolic acid. The action is represented 
by the equation 
CisHsOs+2HO=—C14H6Os.-+-CiHiOc. 
In its pure state glycolic acid is a syrupy liquid, which does not crys 
and Strecker consider gromrs that benzo-glycolic acid may be regene 
rated by the direct union of its constituents. The experiment was not 
tried from want of material. On the other hand, however, lactic and 
benozic acids when heated together for some time at 180° till water is 
no longer disengaged, form a resinous mass which contains an acids 
C29H10QOs, which the authors call benzo-lactic acid, and which is the 
homologue of benzo-glycolic acid ; the reaction is 
C1aH604+-CoH eOc=C2oH100s+2HO.

when piperine is distilled with from 24 10 3 times its weight of potash- 
lime, the product of the distillation consists not merely, as Rochleder and 
Weitheim have stated, of picoline, but of a mixture of two distinct vol 
atile bases. The most volatile product which forms more than Syths 
the basic liquids boils at exactly 100° C., toward the close of the distilla- 
tion the thermometer rises, and at 210° again becomes stationary. +
