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

 ris, or of ceruffa 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 uicers are healed a folution of corrofive 

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

 weeks behind the ear, and among ft 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 moiftened with a folution of half ar^ 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 iolution of arfenic externally applied cures the itch, but re- 

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



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

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

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

 rags moiftened 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 Simulates inflam- 

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

 vefiels 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 amongfl 

 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 refiftance to the progrefs of abforb- 

 ed fluids ; and the ftimulus of lead then increafes the a&ion 

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

 inflamed part prefently difappears. 



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

 two (hirts, 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 feen feven parts of bark in fine powder mixed with 

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

 fcrofulus ulcers, and renewed daily, with great advantage.
