Although less certain in its action than the Acetate of Lead, Gallic Acid, and other remedies, it is a very useful adjunct to other treatment. Dr. W. Frazer states that in passive HAemorrhage from the Lungs, Bowels and Uterus, he frequently combines it in solution with Gallic Acid. In HAematemesis, it proves more useful than in the other forms, probably from the fact of its coming in contact with the bleeding surface. In Uterine HAemorrhage, it has long been extensively prescribed in combination with Tincture of Opium and Infusion of Roses.
2684. In Calculous Affections, in the Phosphatic Diathesis, and when the Urine is of an Alkaline character, Sulphuric Acid has in many cases proved successful in correcting the alkalescence, but it is generally inferior in efficacy to the Nitro-muriatic Acid. Dose, xv. - xxx., three or four times daily.
2685. In Cholera and the painless Diarrha premonitory of Cholera, Dilute Sulphuric Acid in full doses has been of late extensively prescribed. It is recommended to be given in doses of xx. - xxx., at short intervals of an hour or less. In ordinary Choleraic Diarrhoea, the same doses may be prescribed at longer intervals. This treatment has been advocated by Mr. Cox,* of Kensal-town, Dr. Fuller, Dr. Millar, Mr. Willing. and many others. In the Non-inflammatory Diarrhoea of Children, if the tongue be clean, the Dilute Acid may be given in doses of ij. - v., or more, according to age, with great probability of success. In Passive Diarrhoea, depending upon a relaxed condition of the mucous membrane of the intestines, the dilute acid, in doses of x. - xv., with T. Opii, generally proves successful. In Puerperal Diarrhoea depending upon Intestinal Irritation, Sir C. Locock§ states that the Dilute Sulphuric Acid, with a few drops of T. Opii, sometimes effectually restrains the diarrhoea, and improves the character of the tongue, particularly if there are aphthous ulcerations. In the Diarrha of Typhoid Fever, Dr. H. Kennedy|| states, after ample experience, that by far the best remedy is Dilute Sulphuric Acid (f3j. - f3iij. ad Aq. fviij.). It is best to begin with a small dose and increase it as required. The diarrhoea should not be too suddenly checked. Opiate enemas to allay tenesmus are to be used.

2686. In Leucorrha occurring in Cachectic Constitutions, the Sulphuric and other mineral acids are stated to be sometimes very successful. More than two centuries ago, it was strongly recommended by Fonesca; ¶ and Weikard** employed it with great success. Fonesca's formula consisted of gutt. xij. - xv. of the strong acid in Oiv. of Rose-water. Of this, fj. was taken every morning. It is rarely employed at present, but it may occasionally prove useful by its tonic property.
2687. In the Profuse Perspirations of Phthisis, the dilute acid, in doses of x. - xxx., proves highly useful. Dr. Elliotson states that he has seen it check the most severe forms; and Dr. Christison remarks that, of all internal remedies for the same end, none equals Sulphuric Acid, which, in this way, is one of the most efficacious astringent refrigerants. Dr. Graves advises it to be given in combination with Hyoscyamus.
2688. In the advanced stages of continued Fevers, and in Typhus Fever, the internal administration of Sulphuric Acid, with some tomic infusion, appeals to be of great service. Prof. Huss§§ found that, when there was profound prostration, with commencing bed-sores and persistent diarrhoea, Sulphuric Acid, in combination with Infus. RosAe or Infus. ArnicAe Mon., was productive of much benefit. (See Acids, part ii.)

2639. In Confluent Small-pox, when the pustules are filled with a bloody sanies, and the urine contains portions of broken-down coagula of blood, Dilute Sulphuric Acid is stated by Dr. Thompson to be a remedy of the highest value, indeed the only one which can be relied upon. Its use should be combined with wine, tonics, &c.
269"). In Scarlatina, Dilute Sulphuric Acid, with the addition of a little syrup and water, forms an excellent refrigerant medicine, particularly for children. For the Sore Throat, which accompanies this disease, and also in Cynanche Tonsillaris, the Infusion of Roses, acidulated with Sulphuric Acid, forms an eligible gargle. The mouth should always be well washed out after its use.
