stannic ethylomethide is easily

distillation was then interrupted, and the straw-coloured liquid reinaini „ 
was submitted to analysis. It yielded the following results

II. -5620 8™. gave -3278 grm. carbonic acid and -1161 gim. waten 
III -5487 grm. gave -3203 grm. carbonic acid and 1696 gim. uater 
IV -^02 grm., decomposed with alcoholic potash, the solution then acid^ed with 
nitS'acid, and precipitated with nitrate of silver, gave -6146 grm. iodide of silver.
