390 CHEMISTRY. 



Grimaux has succeeded in producing the alkaloid codeine, by tHe 

 action of methyl iodide in presence of sodium upon an alcoholic solution 

 of morphine. Its properties are identical with those of the natural 

 codeine. If ethyl iodide be used in place of the methyl compound, a ne vt^ 

 alkaloid, a homologue of codeine is produced. The author proposes 

 the term codeines for the class, codomethyline, codethyline, etc., for the 

 individual members of it. {G. B., May, 1881, xcii, 1140, 1228.)
