On the other hand, when dichlorobenzylamine was left in 
a stoppered bottle for a few days, it was found that small crys- 
tals made their appearance on the sides of the bottle in con- 
tact with the liquid. On opening the stopper, a pressure was 
felt from within, and besides the smell of this compound, a dis- 
tinct smell of free chlorine was gee The bottle was stop- 
pered again and allowed to remain, the pressure being released 
from time to time; the whole liquid ultimately solidified into 
a mass of crystals, which on examination was found to be ben- 
zoic acid. The reaction is explainable thus :— 
C,H,CH,NCl, + 0,=C,H,.COOH + HCl + N + Cl. 
the oxygen required for the reaction being evidently obtained 
from air confined in the bottle. The above equation necessi- 
tates the liberation of oe which could not be detected

agement in carrying on the above investigation.
