already described, can be prepared from this body as well as from 

 chloraeetine, by exposing it to the action of acetate of silver. The 

 process is the same as that I have already given, with this difference, 

 that the reacting bodies must not be heated above 150C. The 

 ether prepared in this manner gave the following numbers on ana- 

 lysis :

The quantity of this substance at my disposal was so small (the 

 greater part of my product having been lost) that I could not purify 

 it completely ; hence the experimental numbers do not exactly accord 

 with the theoretical. 



Action of Hydrochloric and Benzoic Acids on Glycol. Formation 

 of Chlorbenzoate of Glycol. 



A mixture of equivalent quantities of glycol and benzoic acid, pre- 

 viously fused and powdered, was exposed to the action of dry hydro- 

 chloric acid gas for several heurs, the mixture being maintained at 

 the temperature of 100 during the action of the acid, as in the case 

 of the former compounds. The product thus formed presented the 

 appearance of a soft white solid, and contained a considerable quan- 

 tity of uncombined benzoic acid. This was removed by agitating it 

 with hot water, till, on cooling, it no longer became solid, but re- 

 mained perfectly fluid. Finally it was dissolved in alcohol, and pre- 

 cipitated by water. The body thus prepared, and without being 

 distilled, was analysed, having been previously dried in vacuo over 

 sulphuric acid. Another specimen, prepared in the same manner, 

 at a different time, was also analysed, having, however, been previ- 

 ously distilled. During the distillation it was observed that not a 

 drop of fluid passed over till the mercury had risen to 254, and be- 

 tween that temperature and 270 the entire liquid distilled over. 

 What passed over between 260 and 270 was collected separately ; 

 this was the portion analysed. The numbers obtained on analysis
