the body, and the affected part is liable to fuppuvate, in which 

 cafe a very dangerous ulcer is formed, and a part of one of the 

 vertebrae is generally found carious, and the patient finks after a 

 longtime under the hectic fever occaficne-d by the aerated or 

 oxygenated matter. 



This difeafe bears no greater analogy to rheumatifm than the 

 inflammation of the pleura, or any other membranous inflam- 

 mation ; and has therefore unjuftly been arranged under that 

 name. It is dnlinguifhed from nephritis, as it is feldom attend- 

 ed with vomiting, I fuppofe never, except the ureter happens 

 to be inflamed at the fame time. 



The pain fometimes extends on the outfide of the thigh 

 from the hip to the ankle, heel, or toes, and is then called fci- 

 atica ; and has been thought to confift in an inflammation of the 

 theca, or covering of the fciatic nerve, as the pain fometimes fo 

 exactly attends the principal branches of that nerve. See Oafs 

 I. 2. 4. 15. 1 6. 



M. M. Venefedtion repeatedly \ calomel ; gentle cathartics 5 

 diluents ; warm bath ; poultice on the back, confiding of camo- 

 mile flowers, turpentine, foap, and opium \ a burgundy-pitch 

 plafter. A debility of the inferior limbs from the torpor of the 

 mufcles, which had previoufly been too much excited, frequent- 

 ly occurs at the end of this difeafe ; in this cafe electricity, and 

 iflues on each fide of the lumbar vertebrse^ are recommended. See 

 Clafs I. 2. 4. 16. 



18. Ifchias. The ifchias confifts of inflammatory fever, with 

 great pain about the pelvis, the os coccygis, and the heads of the 

 thigh-bones, preventing the patient from walking or (landing 

 erect, with increafe of pain on going to ftool. This malady, as 

 well as the preceding, has been afcribed to rheumatifm ; with 

 which it feems to bear no greater analogy, than the inflamma- 

 tions of any other membranes. 



The patients are left feeble, and fometimes lame after this 

 difeafe ; which is alfo fometimes accompanied with great flow 

 of urine, owing to the defective abforption of its aqueous parts ; 

 and with confequent third occafioned by the want of (o much 

 fluid being returned into the circulation ; a lodgment of faces 

 in the rectum fometimes occurs after this complaint from the 

 leflened fenfibility of it. See Clafs I. 2. 4. 15. 



M. M. Venefection j gentle cathartics ; diluents •, fomenta- 

 tion ; poultice with camomile flowers, turpentine, foap, and 

 opium; afterwards the bark. See Clafs I. 1. 3. 5. 



When this inflammation terminates in fuppuration the matter 

 generally can be felt to fluctuate in the groin, or near the top of 

 the thigh. In this circumftance, my friend Mr. Bent, furgeon,
