Carbonated iron waters are much esteemed as adjuvants in the management of diabetes; and Dr. Mackey informs me that the bromide of iron, or rather a combination of bromide of potassium and citrate of iron, has given better results than any other medicine in his experience. Of course, the diet and •hygiene must be regulated, and when we can more accurately distinguish the varieties of the malady we may find that certain medicines are more appropriate to some forms than to others, but meanwhile I believe the bromide of iron is available in any ordinary chronic case: I have frequently seen the general health improve, and the amount of sugar grow less under its use.
