must be considered as representing four volumes of vapour, 

 and its formula written c 6 H 6 o 2 . It has been found to give 

 a series generally analogous to that of ordinary alcohol, and 

 Professor Kane proposes for it the name Mesilic 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 6 h 4 , 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 

 c 6 h 6 cl; and, by the decomposition of the latter by means of 

 potash, a body c 6 H 5 o. These may be considered either as 

 containing Mesitylene, or a hypothetic radical Mesityl, 

 thus : 



c e H s + o. Oxide of Mesityl. 



c 6 H 5 -f- cl. Chloride of Mesi- 

 tyl. 



By the action of phosphorus and iodine on mesitic alcohol, 

 there is produced an iodide of mesityl, having the formula 

 c 6 h 5 I. 



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 persulphomesitylates ; and a very anomalous 

 character in these salts is, 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 



so 3 + c 6 H J o+cao + Ho; 



c 6 h 4 + ho. Hydrate of Mesity- 

 lene. 



c 6 h 4 4- hc£. Muriate of Mesi- 

 tylene.
