3. Lepra. Leprofy. Leprofy of the Greeks. The (kin is 

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

 moiil beneath, and itching. Th.e fcales on the head or arms of 

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

 matter defigned for the purpofe of lubricating the external ikin is 

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

 mation of the fubcutaneous veflels ; 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 depreflion of the fore beneath 

 the furface of the fkin, and the hairs in it becoming \vhite,

 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-lkin 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 raiiins and bread. 

 Abflinence from wine^ beer, and all fpirits, is indifpehfably nec- 

 eflary to the cure. 



4. Elephantiqfis; Leprofy of the Arabs. A contagious dif- 

 eafe ; the fkin is thickened, wrinkled, rough, unftuous, defti-
