26. _In the Chronic Diarrhœa of Natives_, the following mixture has been found useful: Take of Alum ten grains, infusion of Acorus root (12), one and a half ounce, Laudanum, five drops; repeat three or four times daily. _In the Diarrhœa which precedes Cholera, and in the early stages of Cholera_, the following powders are worthy of a trial. Take Alum, Catechu, and Cinnamon, of each, powdered, ten grains, mix with honey, and give at a dose. It may be repeated every one or two hours, according to circumstances. It proves useful also in controlling the _Diarrhœa of Phthisis_. 27. As a palliative in _Diabetes_, "Alum Whey," prepared as directed in paragraph 25, may be tried; under its use the quantity of urine voided is, in some instances, diminished. _In Albuminuria_, also, it has been useful in some instances in reducing the proportion of albumen in the urine. 28. _In Hooping Cough_, when the first or acute stage has passed, no remedy is more generally efficacious than Alum, in doses of three or four grains, every four or six hours for a child from two to three years old. It may be given in the form of powder or in solution (Alum 25 grains, Omum Water three ounces) in doses of a dessert-spoonful every four or six hours for a child from two to four years old. 29. _For Relaxed or Ulcerated Sore Throat, for Ulceration and Sponginess of the Gums, in Salivation, and in Fissures of the Tongue in Consumption_, a very useful gargle or mouth wash is made by dissolving two drachms of Alum in a pint of the decoction of Galls (145) or Babúl Bark (9), and sweetening with honey. _For the small white Ulcers_ (_Aphthæ, or Thrush_) _in the mouths of infants and young children_, a better application is 20 grains of finely powdered Alum, incorporated with one ounce of honey. This may be applied twice daily, with the tip of the finger. _In the severer Ulcerative forms of the disease_ (_Ulcerative Stomatitis_) Alum in fine powder, or in strong solution, proves a more effectual application. 30. There is a disease often confounded with _Gonorrhœa_, where the discharge does not come, as it does in true gonorrhœa, from the urethra, but from a sore or excoriated surface between the prepuce and the head of the penis. For this there is no better application than a solution of Alum, 20 grains in one ounce of water. It may be used twice or thrice daily. The strictest cleanliness should be enforced at the same time. _In Gleet_, a solution of Alum (three grains), in water (one ounce), used as an injection twice daily, is often productive of benefit. _In Leucorrhœa and other Vaginal Discharges_, injections of Alum in decoction of Galls or Babúl bark, as advised in the last paragraph, often prove very useful.
