We thus find 100 of yellow powder, to contain 
Mercury 86,46 
Chlorine (aa) 
E.—105,28 grains of yellow powder were dissolved in muriatic acid, and the solu- 
tion having been somewhat diluted, was decomposed by a current of sulphuretted 
hydrogen gas. The perfectly black sulphuret was collected on a weighed filter, and 
the liquor evaporated to dryness, and the residual sal-ammoniac, weighed : 
The filter and sulphuret 126,71 
Filter - - 23,00 
Sulphuret of mercury 103,71, consisting of 
Sulphur - . 14,22 
Mercury - - 89,49 
The sal-ammoniac weighed 12,86 grs. consisting of 
Chlorine - = 8,50 
Hydrogen - »24 
Ammonia = 4,12 
Therefore, the yellow powder consisted of 
in 105,28 parts— in 100 parts— 
Mercury 89,49 Mercury 85,00 
Ammonia 4,12 Ammonia 3,91 
Summing up these different results, we haye—

C 86,23 7,77 8,83 
D 86,46 7,55 
E 85,00 3,91 
And taking the mean result of all, we get, for the composition of this yellow 
powder,
