2549. In Purpura Haemorrhagica, The Following Formula, Proposed Originally By Dr

Stevens,* has been found useful: -

2550. In Diseases of the Skin, particularly in these of a papular and scaly character, M. Devergie has extensively employed the alkalies, both internally and externally. The Bicarbonate of Soda is the one chiefly used, the corresponding salt of Potash being found more caustic and irritant. Internally, the dose is gr. xv. daily, in some bitter infusion, or in Syrup (ss., Syr. Simp. fviij.); and this quantity is augmented gr. viij. every third day, until 3j. is taken in the twenty-four hours. This is the maximum quantity. Externally, he employs lotions, baths, powders, and ointments. The baths are to contain each from viij. to xvj. of the Carbonate, either of Soda or Potash. The lotions contain 3ij. - 3iij. of the salt in Oj. of water; and are employed chiefly in Eczema and Impetigo of the Scalp. The alkaline powder (1 part of Soda, 10 of Starch) is used principally as a depilatory, in Tinea and Sycosis Menti. The ointments are of various strengths, according to the nature of the disease; thus, in Lichen and in its various forms, the strength is gr. viij. - xv. to j. of Lard; in Lepra, Psoriasis, and Ichthyosis, gr. xv. - 3ss. to j.; and in Porrigo Favosa, 3ss. - 3j. to j., with a grain or two of Quick-lime. In Porrigo Larvalis, lotions containing this salt have been found highly serviceable.

2551. In Albuminuria, Dr

Osborne advises the internal use of the alkalies. Alkalescence, he observes, is a necessary condition of the blood, and that the free alkali is Soda, and that when the Soda fails, either from a deficient supply, or from want of power to decompose the Chloride of Sodium in the stomach, the result will be coagulation of the blood in the capillary vessels, and phenomena of inflammation in those parts in which such coagulation takes place; and that Potash or Soda taken into the stomach, either uncombined or as carbonates, have the power of rendering the urine alkaline and of dissolving fibrine. On these grounds, he reasons that, when in any disease the kidneys contain fibrinous deposits, alkalies should be given. He employs the following: -2551 In Albuminuria Dr 214 SodAe Carb., Liq. PotassAe āā 3ij., Decoct. Chondri Crisp, fviij. Dose, a tablespoonful every two hours, in milk. When anaemia is very marked, he adds the Tartrate of Iron.
