j. Lepra. Leprofy. Leprofy of the Greeks. The fkin is 

 lough with white branny fcales, which are full of chinks ; often 

 moift beneath, and itching. The fcales on the head or arms of 

 fome drinking people are a difeafe of this kind. The perfpirable 

 matter defigncd for the purpofe of lubricating the external fkin is 

 fecreted in this difeafe in a too vifcid flate, owing to the inflam- 

 mation of the fubcutaneous vefTcls ; and, as the abforbents act 

 too ftrongly at the fame time, a vifcid mucus is left adhering to 

 the furface of the fkin. 



In the leprofy of the Jews, defcribed in the thirteenth and four- 

 teenth chapters of Leviticus, the deprefhon of the fore beneath 

 the furface of the fkin, and the hairs in it becoming white, feem 

 to have been the principal clrcumftances, which the prieft was 

 directed to attend to for the purpofe of afcertaining the dif-» 

 cafe.

 thrice a day, with half a pint of decoction of elm-bark ; or of 

 malt-tea ; or tincture of cantharides, from 20 to 60 drops, four' 

 times a day ; or fublimate of mercury, with much diluting 

 fluid. Acid of vitriol ? Perhaps the cure chiefly depends on 

 much dilution with water, from two to four pints a day, in 

 which elm-bark, or pine-buds, or juniper-tops, may be boiled. 

 Bath or Buxton water drunk in large quantities. Warm bath. 

 Oil-fkin bound on the part to confine the perfpirable matter. 

 Ointment of tar and fuet ; or poultice for two or three days, and 

 then cerate with lapis calaminaris. Diet of raifina and bread. 

 Abftinence from wine, beer, and all fpirits, is indiipenfably nec- 

 eflary to the cure. 



4. Elephantinfis. Leprofy of the Arabs. A contagious dif- 

 eafe ; the ikin is thickened, wrinkled, rough, unftuous, ceiti-

 and under the joints of the knees and elbows ; and that which

 not eafily infect even a bed-feljow, and refills the ufual means of 

 cure by brimftone.
