![nitrile hydrochloride were dissolved in 100 c.c. of water, 16 grams of iron filings added, and 50 c.c. of hydrochloric acid added slowly during an hour, with shaking. At the end of the reaction, the product was evaporated to dryness, distilled from a copper flask with sodium hydroxide, and the base in the distillate isolated as hydrochloride. The yield amounted to 10 per cent, of the theoretical. With Zinc and Hydrochloric Acid.—To a solution of 6-8 grams of the hydrochloride in 100 c.c. of water, 30 grams of zinc were added, and 70 c.c. of concentrated hydrochloric acid added, as above, the product being then treated as in the previous reduction. The yield of ethylenediamine dihydrochloride amounted to 25 per cent, of the theoretical. In conclusion, the author would thank Messrs. R. R. Baxter and J. A. Goodson for assistance in the preparation of the ethylene dichloride and ethylenediamine which formed the basis of the investigation. Wellcome Chemical Research Laboratories, London.
