6o SORBENTIA. Art. IV. 2. 9. 3, 



In the former cafe the application of a cerate of lapis calamina- 

 ris, or of cerufTa in dry powder, or of rags dipped in a folution 

 of fugar of Lead, increafes the abforption in the ulcers, and pre- 

 vents the effufion of the faline part of the fecreted material. 

 The latter is to be prevented by cleanlinefs. 



After the eruptions or ulcers are healed a folution of corrofive 

 fublimate of one grain to an ounce of water applied for fome 

 weeks behind the ear, and amongft the roots of the hair on one 

 fide of the head, where the mouths of the lymphatics of the 

 neck open themfelves, frequently removes thefe tumours. 



3. Linen rags nioiftened with a folution of half an ounce of 

 fugar of lead to a pint of water applied on the eryfipelas on ana- 

 farcous legs, which have a tendency to mortification, is more 

 efficacious than other applications. White vitriol fix grains 

 diflblved in one ounce of rofe water removes inflammations of 

 the eyes after evacuation more certainly than folutions of lead. 

 Blue vitriol two or three grains diflblved in an ounce of water 

 cures ulcers in the mouth, and other mucous membranes, and 

 a folution of arfenic externally applied cures the itch, but re- 

 quires great caution in the ufe of it. See Clafs II. 1. 5. 6. 



A feeble old man with fwelled legs had an eryfipelas on both 

 of them ; to one of thefe legs a line powder of Peruvian bark 

 was applied dry, and renewed twice a day j on the other linen 

 rags moiltened with a folution of faccharum faturni were appli- 

 ed, and renewed twice a day ; and it was obferved, that the 

 latter healed much fooner than the former. 

 « As the external application of calx of lead ftimulates inflam- 

 ed parts very violently, if it be applied too early, before the 

 veflels are emptied by evacuations, or by the continuance of the 

 difeafe, it is liable to increafe the inflammation, or to induce 

 mortification, as in ophthalmy ; and in a cafe, which was re- 

 lated to me of a perfon who much pricked his legs amongft 

 gorfe, which, on the application of Goulard's folution of lead, 

 mortified with extenfive floughs. But where the fyftem is pre- 

 vioufly emptied, there is lefs refinance to the progrefs of ab- 

 forbed fluids ; and the ftimulus of lead then increafes the ac- 

 tion of the abforbent fyftem more than of the fecerning fyftem, 

 and the inflamed part prefently difappears. 



4. Bitter vegetables, as the Peruvian bark, quilted between 

 two fliirts, or ftrewed in their beds, will cure the ague in chil- 

 dren fometimes. Iron in folution, and fome bitter extract, as in 

 the form of ink, will cure one kind of herpes called the ringworm. 

 And I have {cen feven parts of bark in fine powder mixed with 

 one part of cerufe, or white lead, in fine powder, applied dry .to 

 fcrofulous ulcers, and renewed daily, with great advantage.
