in these animals were similar to those occasioned in man ; they were 

 at first nervous, and then followed by intestinal inflammation. One 

 phenomenon especially remarkable, was the production of an enor- 

 mous quantity of ammoniacal gas in the intestines; this resulted from 

 an organic secretion, for the fatty poisoning matters did not contain 

 any ammonia whatever. — Ibid. June 1829. 



BROMIDE OF CARBON, BY M. SEIIULLAS. 

 To form this compound, two parts of bromine are to be added to 

 one part of periodide of carbon, and just enough solution of potash 

 is to be added to cause the iodine, set free, to disappear; die liquid 

 bromide of carbon which will appear at the bottom of the solution, is 

 to be separated by a funnel or otherwise, but without washing with 

 water, and allowed to stand until it has become quite clear ; during 

 this time a quantity of iodate of potash, in crystals, will rise to the 

 surface ; the clear fluid beneath is to be withdrawn, and put into a 

 weak solution of potash, for the purpose of decomposing a little prot- 

 iodide of carbon formed at the same time ; a little bromide is also 

 decomposed, but that which remains is soon left in a pure state. 



This bromide very much resembles the protiodide of carbon ; they 

 are both heavier than water, have at first the same appearance under 

 its surface, the same ethereal and penetrating odour and sweet taste; 

 both are liquid, and when washed with solution of potash to remove 

 the impurities, both are colourless. 



The differences between the bromide and the iodide of carbon are 

 as follows : the first becomes solid, hard, and crystalline, at 32° Fahr., 

 and remains solid up to 46° ; the latter remains fluid at the lowest 

 temperatures. The first when heated in a spirit flame, gives red va- 

 pours, the latter violet vapours ; neither burns with flame ; but the 

 fluid liydrocarburet of bromine does burn with flame. Neither of the 

 two appears to act upon water, but a little alkali added, causes their 

 decomposition slowly. 



The antilogy which exists between the compounds of chlorine, bro- 

 mine, and iodine, is very remarkable when these bodies are combined 

 with carburetted hydrogen or with carbon. 



1st. Three etliers, considered by M. Chevreul as hydrochlorate, 

 hydrobromate, and hydriodate of carburetted hydrogen, 



2nd. Chlorine and Carbon. Two chlorides of carbon, one solid and 

 the other liquid, possessing a camphorated aromatic odour. 



3rd. Bromine and Carbon. One bromide of carbon, which is fluid, 

 of an ethereal penetrating odour, solidifying at 32° Fahr., tastes very 

 sweet. 



4th. Iodide and Carbon. Two iodides of carbon ; one solid, crystal- 

 line, with a strong aromatic sattron-like odour ; the other fluid, with 

 a penetrating ethereal odour : both sweet to the taste. 



5th. Chlorine and CuTburetted Ilijdrofren. liydrocarburet of chlo- 

 rine, but ougiU to be termed chloride of carburetted hydrogen : tliis 

 compound is liquid, has an ethereal odour and a sweet taste. 



6th. liromine and Carburetted Hydrogen. Hydrocarburct of bro- 

 mine {brom'ulc of carburetted hydroqen). This substance is liquid, has
