    in cold water, and which I believe to be a double salt of quinine and iron with iodine. This decomposition is, how- ever, worthy of investigation. FEREI LACTAS.—LACTATE OF lEON. Lactate of Protoxide of Iron—Ferrous Lactate. Pre- paration—Lactate of iron is best obtained by the pro- cess of Lepage, in which double decomposition is effected between solutions of lactate of lime and protosulphate of iron. Lactate of lime . . .100 parts. Boiling water . . . 600 „ Protosulphate of iron . . 62 parts. Boiling water . , . 600 „ Lactic acid , . . 2 „ Mix both solutions, and having heated the mixture in a water-bath with agitation, filter to separate the precipi- tated sulphate of lime. Then boil the filtrate in a porce- lain dish containing a little iron wire, until reduced to one- half its original volume; filter, and allow it to stand for twenty-four hours. Collect the deposited crystals, wash them with a small quantity of alcohol, and dry them by pressure between folds of bibulous paper. The mother liquor is to be evaporated as long as it continues to afford crystals. The lactate of lime may conveniently be prepared by 'the process of Gobley,* in which casein is made to convert * Jour, de Phar., 3e Ser., vi., 54,
