Class I. i. 4. io. OF IRRITATION. 43 



M. M. It fhould be dufted over with very fine powder of 

 gum fauidarach, and then replaced. Aftringent fomentations j 

 as an infufion of oakbark, or a flight folutiou of alum. Hori- 

 zontal reft frequently in the day. 



10. Lumbricus. Round worm. The round worm is fuf- 

 pected in children when the belly is tumid, and the countenance 

 bloated and pale, with fwelllng of the upper lip. The genera- 

 tion ofthefe worms is promoted by the too dilute ftate of the 

 bile, as is evident in the fluke- worm found in the biliary du£ts 

 and fubftance of the liver in Iheep ; and in water-rats, in the 

 livers of which laft animals they were lately detected in large 

 numbers by Dr. Capelle. Transactions of the college st Phila- 

 delphia, v. i. 



Now as the dilute ftate of the bile depends on the deficiency 

 of the abforption of its thinner parts, it appears, that the tumid 

 belly, and bloated countenance, and iwelled upper lip, are con- 

 comitant circumftances attending the general inactivity of the 

 abforbent fyftem ; which is therefore to be efteemed the remote 

 caufe of the generation of worms. 



The fimplicity of the ftructure of worms probably enables 

 them to exifl in more varioua temperatures of heat ; and their 

 being endued with life prevents them from being de droved by 

 digeftion in the (lomach, probably in the fame manner as the 

 powers of life prei r ent the fermentation and putrefaction of the 

 flomach itfelf. Hence I conclude, that worms are originally 

 taken into our alimentary canal from without ; as I believe fim- 

 ilar worms of all kinds are to be found out of the body. 



M. M. The round worm is destroyed by a cathartic with 

 four or fix grains of calomel; and afterwards by giving fix or 

 eight grains of filings of iron twice a day for a fortnight. See 

 Kepatis tumor, Clafs I. 2. 3. 9. As worms are liable to come 

 away in fevers, whether of the hectic or putrid kind, could they 

 be removed by purulent matter, or rotten Qgg, or putrid fiefh, 

 fince in thofe fevers from the enfeebled action of the inteftineji 

 the fseces become highly putrid. 



The fnarp fpiculae or hairs, which are found on the pods of 

 cowhage, ftruolobium filiqua hirfuta, have been recommended 

 in worm-cafes, and faid to deftroy them by mechanical puncture ; 

 the late Mr. Power of Polefwortl* aflured me, he had had great 

 fuccefs with this medicine and gave about fix or eight grains in 

 a bolus three or four times on one day, with a briih cathartic 

 on the next day. Some have recommended chopped hair or 

 bridles for this purpofe. There are numerous {harp fpicul<e in 

 the fruit of the wild rofe, which might be worth trying it this 



difeafe ;
