The sulphuric acid was determined by heating the substance, till it disappeared, in a 

 small retort containing caustic potash: to the neck of the retort was adapted a tube which 

 was kept cool with wet paper, to prevent any of the oil escaping. The potash solution 

 was transferred to a silver capsule, evaporated to dryness and strongly ignited; — rcdis- 

 solved in water, neutralized with hydrochloric acid, and the sulphuric acid precipitated bj 

 chloride of barium. These arc the results of three experiments:

The products of the decomposition of thr unit ml sulphate of the oxide ofethyle by water. 



When water is added to sulphate of ether, the mixture heated, and from time to time 

 shaken, the oil entirely disappears, leaving a very acid solution, which, when heated, give; 

 off alcohol. If carbonate of barytes be added, until the liquid is saturated, three salts of 

 barytes remain in solution. The filtered solution evaporated by a gentle heat, deposits a 

 small quantity of crystals in the form of scales, before it is well concentrated. Spirits of 

 wine is now added, which precipitates the remainder of this salt. Redissolved in water 

 and precipitated by alcohol, it is obtained in fine white scales, which, when dried, have a 

 pearly lustre. This Bait has the characteristics of metbionate of barytes, with which it 

 corresponds in composition. 0.4035 of the salt, dried at 100°, ignited with SO,Tl <>. n a\.
