TER-CHLORIDE OP CARBON. 
not dissolve in water, either cold or hot, but is soluble in 
alcohol, and still more so in ether. These solutions are not 
affected by nitrate of silver. 
2. A compound of one volume of carbon and two vo- 
lumes of chlorine. Its specific gravity is 1.5526. Although 
liquid, it is insoluble in water. 
3. A combination of equal volumes of chlorine and carbon. 
It occurs as a sublimate. It too is insoluble in water. 
In order to ascertain the properties of the liquid referred 
to in Mr. Tuson's paper, I sent for a small quantity of the 
so-called ter-chloride. It possessed an ethereous character, 
mixed freely with water having a specific gravity of 0.882, 
boiling at a temperature of 170° Fahr., exhibiting an acid 
reaction with moist litmus paper, and affording a white pre- 
cipitate on the addition of nitrate of silver. It is, therefore, 
totally different from any of the compounds heretofore de- 
scribed as chlorides of carbon, but bears a strong resemblance 
to what is sometimes termed chloric ether, a preparation 
which has, I believe, been for years usefully employed as 
an agreeable internal stimulant. 
With the view of testing the topical efficacy of the prepa- 
ration in question, I tried it in three cases ; but regret to 
state, that the results obtained were by no means encouraging. 
Upon the 2d of August last, I prescribed for a patient, la- 
boring under ulcerated cancer of the tongue, a lotion com- 
posed of one drachm to a pint of water. Here it produced 
no benefit beyond that of a simple detergent. The patient 
died after suffering excruciating agony at the end of the 
month. 
Upon the 12th of August I ordered a similar lotion, in the 
hope of procuring some sedative effect in the instance of a 
gentleman under my care, who for several years past has 
been afflicted with extensive and obstinate erosive ulceration 
of the skin surrounding the throat, and which is accompanied 
with most distressing itching and irritation. Under its use, 
however, the whole throat became perfectly raw, the dis-
