Ammonia does not combine directly with the chloride of 
salicyle, but exerts a remarkable action upon it, which will be 
separately described. 
Bromide of Salicyle. 
Bromide of salicyle is made in an analogous manner to the 
chloride. It crystallizes in small colorless needles. Its pro- 
perties and reactions with the fixed alkalies and ammonia do 
not differ from those of the chloride. 
By analysis, 
I. 0.500 bromide gave 0.1 17 water and 0.765 carbonic acid. 
II. 0.400 " " 0.089 " 0.608 " " 
III. 0.582 bromide gave 0.539 bromide of silver.

Action of Ammonia on Chloride and Bromide of Salicyle. 
It was ascertained by M. Wcehler and Leibig that by the 
action of dry ammoniacal gas upon chloride of benzule there is 
produced, hydrochlorate of ammonia and an azoted compound, 
benzamide, composed of benzule, and a body N 2 H 4 which 
is found in oxamide and other analogous combinations. The
