Owing to these results and the experiments of other chemists, the author is of the opinion that the molecule of these compounds coiitains two parted nitrogen atoms, and considers the existence of the following substituted products established.

Obtained by Bunsen (first product), using anhydrous alcoholic solations of ammonia and iodine. I/ \H It appears, then, that the formation of theRe different products is dependent on the conditions under which the explosive cornpound iw prepared, as well as upon its decomposition by water.
