Bromine. Bromine is obtained chiefly from bittern, the mother liquor of sea-water; from Kelp, or the ashes of sea-plants; but it has also been found in the mineral kingdom, in combination with Silver, Zinc, and Cadmium.

Med. Prop, and Action. In its pure state, Bromine is caustic and irritant When properly diluted, and in small doses, it is tonic, diuretic, and resolvent, and increases the activity of the lymphatic system. Its vapour is very irri-tai ing, producing violent cough, a sense of suffocation, neat of the alimentary canal, and general uneasiness. When taken in large doses, it is absorbed into the system, having been detected in the blood and in the urine. In animals poisoned by it, it produced dilated pupil, insensibility, and convulsions. Externally, it may be applied in solution (4 parts of Bromine to 40 of water), or in the form of ointment (gr. x. - xv. to oz. j. of Lard). Dr. Glover regards Bromine as intermediate in medicinal action between Iodine and Chlorine, but nearer that of Chlorine.

562. Therapeutic Uses

In Scrofula, Bromine appears to exercise considerable influence. Dr. Glover * considers it superior in efficacy to Iodine, and it has been supposed probable that the value of Cod-liver Oil in Scrofula depends upon the combination of these two substances, Bromine and Iodine. In 1837, M. Bon-netf pointed out the value of this remedy in Scrofula, and refers to the former researches of M. Pourche. He relates a case of scrofulous enlargement of the glands of the neck, in a woman who had been thus affected for seven years. A cure was completed in three months by the internal and external use of Bromine. At first, gutt. vj. in fiij. of water were given daily, in three doses. Subsequently, gutt. x. were given; in ten days, the dose was increased to gutt. xiv., and at last to gutt. xxx., daily. Cataplasms, moistened with a solution of Bromine, were applied to the swellings. No unpleasant symptoms occurred, and the woman perfectly recovered Other similar cases are recorded. A very good strength for internal use is 1 part of bromine in 40 of water. Of this, the dose to commence with is gutt. vj., three or four times daily. Besides some cases of scrofulous enlargements and scrofulous ulcers, Dr. Glover mentions cases of Eczema and Carbuncle, which recovered under its internal and external use. Bromine has been used as a disinfectant. Mr. Goldsmith, of the United States army, has found the following solution useful as a local application in Hospital Gangrene, Erysipelas, and Sloughing Sores: - Bromine j.; Bromide of Potassium gr. clx.; Distilled Water to make fiv. He has employed the same solution as a prophylactic in wards in which Erysipelas has appeared, and has found the inhalation of the vapour of service in Diphtheria.
