solution is absorbed by strong sulfuric acid and forms ethyl sulfate 

 from which alcohol is made by dilution and distillation. Apparatus 

 No. I was constructed to carry out this scheme. The acteylene was 

 generated in a two-quart Mason fruit jar (b). Water was fed into 

 this jar by means of a bottle (a) elevated so that water siphoned 

 from it would have a fall of six feet. The exit of the acetylene was 

 regulated by a glass valve. The gas then passed through 3 bottles 

 (c) containing lead acetate to take out sulfides, then through an 

 empty flask (d) which was to take care of back pressure and then 

 into the electrolytic cell (e) to be absorbed and regenerated as

ethylene, from here it passed an empty flask {f) to catch water 

 which the gas might carry mechanically, then through three six- 

 teen inch glass tubes (g) filled with calcium chloride, then three 

 bottles (/z) containing strong sulfuric acid (cold) to dry as thoroughly 

 as possible and then into six flasks (?) containing strong sulfuric 

 acid which was heated to 130° to 140° C. by means of a bunsen 

 burner under the sand bath on which they stood. The current was 

 modified by passing 6 32-c. p. lamps so that it was cut down to 6 

 amperes at no volts. This gave approximately 3 liters of hydrogen 

 per hour and the flow of acetylene was so regulated that the quan- 

 tity passing should be about 2^ liters per hour, or about 10 times
