These results afford us sufficient data from which to deduce 
the nature and composition of this body. All the experiments 
of decomposition indicate it to contain chlorine and carbon, 
and those with oxygen and the metals, sufficiently prove the 
absence of hydrogen and oxygen. With regard to the 
proportions of the elements, three grains of the substance 
gave 5.7 cubic inches of carbonic acid gas, therefore two grains 
will give 3.8 cubic inches. One hundred cubic inches of 
carbonic acid gas weigh 46.47 grains, and contain 12.72 grains 
of carbon ; and 3.8 cubic inches will therefore contain 0.483 
grains of carbon. The two grains of the substance decom- 
posed by heated lime gave 5.9 grains of chloride of silver, 
which, according to Dr. Wollaston’s scale, equal 1.45 of 
chlorine; hence the two grains gave chlorine - - - 1.45 
carbon - - - .483 
The loss here is 0.067, which is by no means important, 
when the small quantity of the substance and the nature of 
the experiments are considered. 
As to the proportion of these two bodies to each other, if 
we consider chlorine as represented by 33.5, and carbon by 
5.7, or with Dr. Wollaston by 44.1 and 7.5, then the 1.45 
of chlorine would be equivalent to 0.2466 of Carbon. This 
is the constitution of the fluid or proto-chloride of carbon ; 
and if we double the 0.2466, the product 0.4932, approaches 
so near to the experimental result 0.483, that we do not hesi- 
tate to regard this compound as consisting of one portion of 
chlorine and two portions of carbon, or 
chlorine - - - 44.1 - - - 33.5 
carbon - - - 15 - - - 11.4
