so that the atom of hydrogen in the hydruret of salicyle be- 
comes replaced by an equivalent of chlorine, as in the analo- 
gous compounds of benzoyl and spiroil. 
Bromide of Salicyle, 
This compound is produced whenever bromine is added to 
hydruret of salicyle, heat is evolved, and the whole consoli- 
dates into a crystalline mass, which, like the chloride, may be 
purified by solution in alcohol and subsequent crystallization. 
In this substance the hydrogen of the hydruret is replaced by 
an equivalent of bromine, the whole consisting of 
Atoms.

Combinations of Salicyle nsoith Amidogene. 
When a current of gaseous ammonia is passed over chloride 
of benzoyl, it has been shown by Woehler and Liebig to suffer 
decomposition ; a mixture of chloride of ammonium and ben- 
zamide being produced, the latter compound being a combi- 
nation of benzoyl with amidogene (N + 2 H), analogous to 
oxamide. 
When a current of dry ammonia is passed over chloride of 
salicyle it becomes absorbed, and a yellow pasty mass results, 
which must be frequently broken up and again exposed to 
the gas to effect its entire decomposition. No hydrochlorate 
of ammonia is formed, the ammonia removing oxygen from 
the compound without abstracting any chlorine, and forming 
water, which condenses in the tube in which the experiment 
is performed. The resulting compound is Chlorosamide \ it
