Characteristics.-Some forty years ago, when the germ theory of disease in its present form was in its infancy, Dewar, of Fife, conceived the idea that Sulphurous acid was an innocent and at the same time universal germ destroyer, and consequently universal remedy. His views met with cordial acceptance, and inhalations of Sulphurous acid given off from burning Sulphur became the fashion. Dewar's method was simple. A few red cinders were put in a kitchen shovel; this was placed in the centre of a room and flowers of sulphur sprinkled thereon. In a very short time every person in the room was sneezing violently, coughing and wheezing, and running at the eyes and nose. Dewar also used the ordinary solution and a spray. Among the special diseases arrested by Suls. ac. Dewar named: Chilblains; chapped hands; diphtheria; scarlatina maligna; erysipelas (a local application of equal parts of the B. P. acid and glycerine); cold in the head, influenza, asthma, bronchitis, croup, clergyman's sore throat, chronic phthisis; typhoid fever. Wounds, sore nipples, bruises were also amenable to its local use. As one who has undergone the "fumigation" process (it was supposed to prevent all sorts of maladies, as well as cure, and I suppose it was with that object that I was made to "prove" Suls. ac. in my boyhood), I can testify to its homoeopathicity in the "cold, coughs, asthma, and influenza" part of Dewar's recommendations. Suls. ac. doubtless shares the antiseptic properties of Sulph. The symptoms of the Schema are from observations of the effects on workmen in mines, from air contaminated with Suls. ac., with a few additions of my own. Milne sums up its virtues thus: "Antiseptic, disinfectant; a powerful deoxidiser and destroyer of vegetable life." As a gargle it is used in the strength of one to six. In parasitic skin affections the B. P. solution is used and is effective. Internally, says Milne, it "does good in sarcina" in doses of min. xxx. to lx., well diluted with water. Ringer (who endorses most of Dewar's recommendations) says that ten to fifteen minims taken ten minutes before each meal will remedy pyrosis in most instances, and prevents flatulence and fermentations; and that "the solution, either strong or diluted, in varying proportions, speedily removes thrush." This case touches a homoeopathic characteristic of Suls. ac.-ulcerative inflammation of the mouth. It has cured this in the attenuations. The headache of Suls. ac. is > by vomiting. C. Wootton tasted the acid (H. W., xxvi. 204) with this result-it at once stopped the mucous secretion of the bowels, producing scybalous motions. The constipation was so severe that he was in misery for nine months, till he took Hydrast., which cured. The use of Suls. ac. as a hair-wash at a later time produced the same result.
