every night, and wafhed off with foap and water next morning, 

 till every part is cleared , with lac fulphuris twenty grains to be 

 taken every morning inwardly, Warm faline bath, with white 

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

 hog's fat. With either of which the body may be fmeared all 

 over. 



Mr. Grille fays, that thofe who get manganefe from its mines 

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

 pofed of fix parts of finely levigated manganefe and of fixteen 

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

 common ufe. Parmentier. 



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

 dicted to fpirituous 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 

 fcratching themfelves. I faw fatal effects m one fuch patient* 

 by a too extenfive ufe of a folntion of lead ; the eruption dif ap- 

 peared, he became dropfical, and died ; I fuppofe from the too 

 ifuddenly' ceafmg of the great ftimulus caufed by the eruptions 

 Over the whole fkin, as in the preceding article. 



M. M. The patient mould gradually accuftom himfelf to half 

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

 pound of fait to every three gallons. Mercurial ointments on 

 fmall parts of the fkin at a time. A grain of opium at night in- 

 ftead of the ufual potation of wine or beer. 



8. Herpes. Herpes confifts of gregarious fpreading excoria- 

 tions, which are fucceeded by branny fcales or fcabs. In this 

 difeale there appears to be a deficient abforption of the fubcuta- 

 neous mucus, as well as inflammation and increafed fecretion of 

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

 its acrimony, but is very faline to the tafte, as fome of thefe pa- 

 tients have aflured 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 fcratching themfelves. 



It is liable to affect the hands, and to return at diftant periods 5 

 and is probably a fecondary difeafe, as well as the zona ignea, or 

 Ihingles, defcribed below. 



M. M. Poultice the eruption with bread and milk, or ra\r 

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

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

 parts with frefh cerate mixed with lapis calaminaris. On the 

 parts not excoriated mercurial ointment, made of one part of 

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



feciiozs,
