 beer. Opium, from a quarter of a grain to half a grain twice 

 a day. Sorbentia. Tincture of digitalis, thirty drops twice a

22. Sclrrhus. After the abforbent veins of a gland ceafe to 

 perform their oiHce, if .the feeerning arteries of it continue to 

 act fome time longer, the fluids are pufhed forwards, and ftag- 

 nate in the receptacles or capillary vefiels of the gland ; and the 

 thinner part of them only being refumedby the abforbent fyftem 

 of the gland, a hard tumour gradually fucceeds ; which contin- 

 ues like a Hfelels mafs, till from fome accidental violence it gains 

 fenfibility, and produces cancer, or fuppurates. Of this kind 

 are the fcirrhus glands of the breafts, of the lungs, of the mefen- 

 tery, and the fcrofulous tumours about the neck and the bron- 

 chocele. 



Another feat of fcirrhus is in the membranous parts of the 

 fyftem, as of the rectum mteftinum, the urethra, the gula or 

 throat ; and of thus kind is the veruca or wart, and the clavus pe- 

 dum, or corns on the toes. A wen fometimes arifes on the back 

 ef .the neck, awd fometimes between the moulders ; and by dif- 

 tending the tendinous fafcia produces great and perpetual pain. 



M. M. Mercurial ointment. Cover the part with oiied filk. 

 Extirpation. Electric ihocks through the tumour. An iiiue 

 into, the fubftance of the wen. Opium. Ether externally. 



23. Scirrbus re'fti inteftini. Scirrhus of the rectum. A 

 fcirrhus frequently affects a canal, and by contracting its diam- 

 eter becomes a painful and deplorable difeafe. The canals thus 

 obltructed are the rectum,- the urethra, the throat, the gall- ; ciucts, 

 and probably the excretory ducts of the lymphatics, and of oth- 

 er glands. 



The fcirrhus of the rectum is known by the patient having 

 pain in the part, and being only able to part with liquid feces, 

 nd by the introduction of the finger j the fwelled part of the 

 teftine is fometimes protruded downwards, and hangs like a 

 valve, fmooth and hard to the touch, with an aperture in the 

 centre of it. See a paper on this fubject by J. Sherwin. Me- 

 moirs of a I^ondon Medical Society, Vol. II. p. 9.
