IN the course of our work with the copper-zinc couple, we described somewhat brieflr a series of bodies which may be regarded as zinc ethylate in which chlorine, bromine, or iodine has taken the place of one CzH50, and which may well be termed zinc-halogen etlylates. The non-crystalline character of these compounds, coupled with the difficulty of removing the alcohol with which they necessarily become associated, render their study difficult and after all unsatisfactory. W e thought, however,
more » ... at some knowledge of the reactions of bodies of this character might be obtained, could we succeed in replacing the zinc by some other metal. W e therefore set to work in the hope of preparing an analogous aluminium compouiid, and in so doing observed a phenomenon which induced us t o undertake the experiments detailed below. We give them much in the order in which they were made, Experiment I.-2 grams of aluminium-foil 42 em. long, 5 cm. aide, cut in small pieces, were placed in a flask with 20 C.C. of water and 7 grams of iodine. Evolution of gas, which proved to be hydrogen, took place a t once at the ordinary temperature. The flask was kept in wat.;.r at 1 2 O , and the following iiieasurenients made :-Collected in the first 15 minutes .
