fluids, as well as ammonia, it readily dissolves, in the latter 

 case undergoing some remarkable changes. From its solu- 

 tions in the fixed alkalies, acids throw it down unchanged. 

 Submitted to ultimate analysis, chloride of salicyle is found

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

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
