into muriatic acid gas and mesltylene. Notwithstanding the care that may be 

 taken in this process, it is difficult to get a product free from mesitic alcohol or 

 ether. In only one analysis did I obtain a result conformable to theory, and 

 consequently that one only need be subjoined. 



A. 0.483 gramme material gave 



0.294 water. 

 0.826 carbonic acid. 

 From whence results 



Carbon = 47-27 

 Hydrogen = 6.67 



B. 0.673 material gave 1.252 gramme chloride of silver, corresponding to 

 45.88 chlorine per cent. 



77.20 100.00 



It is thus evident that the body analyzed in this instance was chloride of 

 mesityl almost absolutely pure. 



IV. IODIDE OF MESITYL. 



When iodine, phosphorus, and mesitic alcohol are treated precisely as in the 

 manner for making hydriodic ether by common alcohol, the reaction takes place 

 in the retort without any separation of carbon. Immense quantities of hydriodic 

 acid gas are disengaged, and the liquid which distils over is very heavy, deeply 

 coloured by iodine, and possesses an odour almost exactly similar to that of 

 hydriodic ether. What remains in the retort is slightly tinged yellow, owing to 

 its being mixed with a small quantity of a yellow substance, which is deposited in 

 spangles, like iodide of lead. The liquid remaining in' the retort solidifies, on 

 cooling, into a mass of fibrous silky crystals. The distilled liquor, washed with 

 water to remove adhering hydriodic acid, is still coloured by iodine, from which
