The compound formed was fluid, and when added to water, 

 was converted into the hydrochloric and arsenious acids, vvith- 

 out the formation of a trace of arsenic acid. It was, therefore, 

 the terchloride of arsenic As CIg. , , , . ,

 This metal combines more slowly with chlorine than any 

 of the preceding. Ten minutes of agitation vvere required to 

 obtain the whole of the heat extricated during the combination.
