or potash should be selected in preference to ammonia, as this latter is not found in the blood or tissues, and is only formed from their decomposition and decay. In the phosphatic iron salt tinder consideration, it Avould seem preferable to use suda with the citric acid in rendering the same soluble Citrate of soda dissolves the freshly-precipitated pyrophosphate of iron as readily as the ammonia salt, and the resultant scales and syrup are equally as beautiful and tasteless. The pyrophosphate
... . The pyrophosphate of iron under consideration, is a scsquioxido salt, and what degree of ready assimilability it may possess, is not as yet, 1 presume, fully ascertained. Doubtless, it is a valuable agent, but hoAv much more so than the numerous other sesquioxide combinations of the metal, can only be learned from extensive trial. Its freedom from unpleasant taste is certainly in its favor. When it is desirable to administer phosphorous compounds with iron, I am inclined to think a lower oxy-salt of the élément, with one of the iron containing also a less amount of oxygen, is to he preferred. The hypophosphite of the protoxide of iron, in the form of syrup, isa stable compound, and possesses the least possible ferruginous taste. In the limited trials to Avhich it has been subjected, it has proved to bo remarkably prompt in its tonic and chalybeate influence, and indeed we should expect this, from what we positively know of the behavior of mineral salts under the influence of vital chemical action.
