1448. Hemeralopia, Or Night Blindness, Was Successfully Treated By

Dr. Smith § with collyriums containing Corrosive Sublimate (gr. ij. ad Aq. fj.). This was dropped into the eye twice daily; and, at the same time, a blister was kept open on each temple. The only other remedies employed were mild aperients.

1449. Diseases Of The Skin

In Obstinate Scabies, a solution of this salt (gr. xx. - gr. xxx. ad Aq. Oj.) is an application which rarely fails to effect a speedy cure. The fear of its becoming absorbed into the system, and producing constitutional effects, is groundless. The same lotion is the best which can be employed to destroy pediculi, commonly called Crab-lice. To allay the intense itching in Pruritus Pudendi, Pruritus Scroti, Urticaria, Prurigo, and other Skin Diseases, Mr. Erasmus \Yilson|| states that the lotion which he chiefly relies on is the following: - ]1449 Diseases Of The Skin 123 Hydrarg. Corros. Sub. gr. v. - x., Spt. Rosniarini, Spt. Vini Rect. aa fj., Mist. Amygd. Amar. fvj., M. It is a very effectual formula. In obstinate Eczema, he applies a saturated solution of the Bichloride in Proof Spirit, by means of a camel's-hair pencil, to the diseased part, with the view of setting up a new action on the surface. He has found a similar application useful in Favus. In Acne Simplex, Acne Rosacea, Ephelts, and Porrigo, the emulsion advised for Pruritus (ante) is also recommended as a good local stimulant. In Sycosis, Dr. Wright ¶ found much benefit from the following lotion: -Hydrarg. Corros. Sub. gr. ij., Acid Hydrochlor. eij., Aq. fviij., M. Alkalies were administered internally at the same time. In obstinate Pityriasis, the internal use of this salt is stated by Dr. Green * to have succeeded when other remedies have failed. In Psoriasis, its internal exhibition, in doses of gr. 1/16, combined with Cinchona and Sarsaparilla, is favourably-spoken of by Sir Philip Crampton; the Citrine ointment to be applied locally at the same time. To Onycha Maligna, a strong solution has occasionally been locally applied with advantage, but it is inferior to Liquor Arsenicalis or T. Iodi. To Corns, an alcoholic solution of this salt was recommended by Mr. Wardrop. He directs the foot to be previously well soaked, and the corn pared down. One or two applications are said to be sufficient to complete the removal. In Frambsia, or Yaws, the internal administration of Corrosive Sublimate, in doses of gr. 1/10 - 1/8, is thought highly of by some West Indian practitioners; and, although it is occasionally productive of benefit, it appears to be very inferior to the Iodide of Potassium (Maxwell). To remove the Blueness of the Skin occasioned by a prolonged use of the Nitrate of Silver, Mr. Erasmus Wilson § suggests the use of washes containing Corrosive Sublimate. In Erysipelas, Dr. Dewees states that a solution of this salt (gr. j. ad Aq. fj.) is as effectual a local application as the mercurial ointment. In Erythema, Dr. Bateman || prescribes a lotion composed of gr. x. of Corrosive Sublimate, in fvj. of Lime Water.
