must be considered as representing four volumes of vapour, 

 and its formula written Cg Hg o^. It has been found to give 

 a series generally analogous to that of ordinary alcohol, and 

 Professor Kane proposes for it the name Mesiiic Alcohol. 



By means of sulphuric acid there is obtained a fluid 

 colourless, of an alliaceous odour, boiling at 276. F. and having 

 the composition c^ h^, to which is given the name Mesity- 

 lene. 



By acting on mesitic alcohol with perchloride of phos- 

 phorus there is generated phospho-mesitylic acid, and a 

 compound fluid heavier than water, which has the formula 

 Cg u^ cl; and, by the decomposition of the latter by means of 

 potash, a body Cg h^ o. These may be considered either as 

 containing Mesitylene, or a hypothetic radical Mesityl, 

 thus: 



Cg H5 + o. Oxide of Mesityl. 



Cg H5 4- cl. Chloride of Mesi- 

 tyl. 



Cg H4 4- HO. Hydrate of Mesity- 



lene. 

 Cg H4 4- ncl. Muriate of Mesi- 



tylene. 



By the action of phosphorus and iodine on mesitic alcohol, 

 there is produced an iodide of mesityl, having the formula 



Oxide of Mesityl unites with sulphuric acid in two pro- 

 portions, forming the sulphate and the bisulphate of mesityl; 

 both of these are acid, and unite with bases forming well 

 characterized salts. 



The salts of the former are called sulphomesitylates, and 

 of the latter per sulphomesitylates ; and a very anomalous 

 character in these salts isj that the quantity of the inorganic 

 base is such as could neutralize the whole of the sulphuric 

 acid which they contain. Thus the sulpho-mesitylate of 

 lime has the formula 



SO3 4- Cg Hj o 4- ca o 4- HO ;
