In some of my previous writings I have presented the marked differences in the action of the bromides of the different earths. I have shown the disadvantages of the use of the potassium bromide as compared with other bromides and have repeatedly endeavored to impress upon my readers the benefit of strontium bromide. It does not produce acne except in very large doses; it does not irritate either stomach, intestinal tract, or kidneys; in fact it is a gastrointestinal sedative, and has a tendency to diminish albumin and sugar in the urine.
All this provided the bromide is chemically pure. It is the common thing to find a very impure article on the market. This salt is especially desirable if it is necessary to give large doses of the bromide, as 60 grains may be given three or four times a day with but little if any unpleasant results. Usually it should be given in simple combinations as incompatibilities with it are common.
