Messrs. Phillips and Faraday on a 
disposal. We have therefore been enabled to continue our 
experiments, and have come to the very unexpected conclu- 
sion of its being another chloride of carbon, in addition to the 
two, an account of which has been published in the Transac- 
tions of the Royal Society for this year. 
The substance, after being boiled in solution of potash, 
washed in water, dried and sublimed, formed beautiful aci- 
cular crystals, which appeared to Mr. W. Phillips to be four- 
sided prisms. They contained no sulphur, and, when dissolved 
in alcohol or ether, gave no traces of chlorine or muriates, by 
nitrate of silver. They burned in the air with a strong bright 
flame at a heat below redness, and agreed with the description 
given by M. Julin of the properties of the substance. 
When heated moderately, it sublimed unaltered ; but on 
passing a portion over rock crystal, heated to bright redness, 
in a green glass tube, it was decomposed, charcoal was de- 
posited, and the gas, passed into solution of nitrate of silver, 
precipitated it, and proved to be chlorine. 
A portion was repeatedly sublimed in a small retort filled 
with chlorine, which was made red hot in several places ; it 
however underwent no change ; but on cooling crystallized 
as at first. It was also exposed in the same gas to sun light 
for many days, but no change took place. A 
When raised in vapour over hot mercury, and detonated 
with excess of oxygen, a quantity of carbonic acid gas and 
chloride of mercury were produced. There was no change 
in the volume of gas used ; and lime water being passed into 
it, absorbed the carbonic gas, became turbid, and left a resi- 
duum of pure oxygen. Acetic acid being then added, to dis- 
solve the carbonate of lime, the solution was tested for
