every night, and washed off with soap and water next morning, 

 till every part is cleared; with lac sulphuris twenty grains to be 

 taken every morning inwardly. Warm saline bath, with white 

 vitriol in it. Flowers of sulphur mixed with thick gruel, or 

 with hog's fat. With either of which the body may be smeared 

 all over. 



Mr. Grille says, that those who get manganese from its mines 

 are not subject to the itch; and that he found an ointment, com- 

 posed of six parts of finely levigated manganese and of sixteen 

 parts of lard, a more efficacious remedy for the itch than those 

 in common use. Parmentier. 



7. Psora ebriorum. Elderly people, who have been much ad- 

 dicted to spirituous drinks, as beer, wine, or alcohol, are liable 

 to an eruption all over their bodies; which is attended with 

 very afflicting itching, and which they probably propagate 

 from one part of their bodies to another with their own nails by 

 scratching themselves. I saw fatal effects in one such patient, 

 by a too extensive use of a solution of lead; the eruption disap- 

 peared, he became dropsical and died; I suppose from the too 

 suddenly ceasing of the great stimulus caused by the eruptions 

 over the whole skin, as in the preceding article. 



M. M. The patient should gradually accustom himself to half 

 his usual quantity of vinous potation. The warm bath, with one 

 pound of salt to every three gallons. Mercurial ointments on 

 small parts of the skin at a time. A grain of opium at night 

 instead of the usual potation of wine or beer. 



8. Herpes. Herpes consists of gregarious spreading excoria- 

 tions, which are succeeded by branny scales or scabs. In this 

 disease there appears to be a deficient absorption of the subcuta- 

 neous mucus, as well as inflammation and increased secretion of 

 it. For the fluid not only excoriates the parts in its vicinity by 

 its acrimony, but is very saline to the taste, as some of these pa- 

 tients have assured me: I believe this kind of eruption, as well 

 as the tinea, and perhaps all other cutaneous eruption, is liable to 

 be inoculated in other parts of the body by the finger nails of the 

 patients in scratching themselves. 



It is liable to effect the hands, and to return at distant periods; 

 and is probably a secondary disease, as well as the zona ignea, or 

 shingles, described below. 



M. M. Poultice the eruption with bread and milk, or raw 

 carrots grated, for two or three whole days, to dilute or receive 

 the discharged fluid, and abate the inflammation; then cover the 

 parts with fresh cerate mixed with lapis calaminaris. On the 

 parts not excoriated mercurial ointment, made of one part of 

 white calx of mercury and six of hog's fat. Internally, after vene-
