1524. In Gangrenous Stomatitis, Hydrochloric Acid was originally proposed as a local application by Van Swieten. The following mode of applying it is advised by Dr. Willshire: - To the ends of two small sticks fix small pieces of sponge, dip one of them into the acid, and slightly damp the other with water; open the patient's mouth as wide as possible, turn the diseased cheek to the light, push aside the tongue, and cover it with a piece of card, to prevent the acid from touching it; then apply the sponge with the acid in close contact with the diseased part, taking care that the whole of the ulcer is subject to its action. Then dip the other sponge into dry Chloride of Lime, and apply it, as in the previous case, to the whole of the diseased surface. Remove it in a minute or two, and wash the mouth out well with water. If necessary, it may be repeated. The constitution should at the same time be supported by Cinchona, tonics, &c. Delpech, Trousseau, and others speak of simple fumigation with the acid fumes as equally efficacious.
1525. In Cynanche Maligna or putrid Sore Throat, the strong acid, applied as directed in the last section, has been advised, when the ulcer assumes an unhealthy or phagedenic character. In mild cases, or if the ulceration extend further than can be 6een, gargles containing the diluted acid may be substituted. It is inferior to the application of Nitrate of Silver. In Aphthous Ulceration of the Mouth of Children, and in mild cases of Cancrum Oris, a linctus made with 3j. of the strong acid and 3j. of Honey is an excellent remedy. (Dr. Symonds.§) In Cancrum Oris, it is often advisable to apply the strong acid to the ulcerated surface.
The results of the experience of Dr. Cotton|| on this point are as follow: - 1. The mineral acids are well suited to a large number of phthisical cases. 2. The dilute Hydrochloric Acid, especially in doses of ex. - xv. twice or thrice daily, is an important auxiliary to other treatment, and may oftentimes be usefully employed, either alone or with other mineral or vegetable tonics. In Phlegmasia Dolens, Dr. Mackenzie* directs fj. of the Dilute Acid in Oij. of Barley Water, with ss. of Chlorate of Potash, to be taken daily.

1527. In Gangrenous Ulceration of the Genital Organs, Van Swieten employed the strong acid, diluted with six parts of water, with great success.
