M. M. A bandage fpread with plafter to cover the whole 

 limb tight. Rags dipped in a folution of fugar of lead. A 

 warm flannel itccking or roller. White lead and oak-bark ? 

 both in fine powder. Horizontal reft. An ingenious treatife 

 on the ufe of bandage, in the cure of ulcers, has lately been pub- 

 limed by Mr. Baynton, of Briftol ; and another, on the fame fub- 

 je6t, by Mr. Whately, of London, who fucceeds without ufmg 

 plafter on the bandage. 



15. Scirrhus fuppuruns. When a fcirrhus affects any gland 

 of no great extent or fenfibility, it is, after a long period of time, 

 liable to fuppurate without inducing fever, like the indolent tu- 

 mors of the conglobate or lymphatic glands above mentioned ; 

 whence collections of matter are often found after death, both in 

 men and other animals j as in the livers of fwine, which have 

 been fed with the grounds of fermented mixtures in the diftil- 

 leries. Another termination of fcirrhus is in cancer, as defcri- 

 bed below. See Clafs I. -2. 3. 22. 



1 6. Carcinoma. Cancer. When a fcirrhous tumor regains 

 its fenfibility by nature, or by any accidental hurt, new veffels 

 {hoot amongft the yet infentible parts of it, and a new fecretiorj 

 takes place of a very injurious material. This cancerous mat- 

 ter is abforbed, and induces fwelling of the neighbouring lymph- 

 atic glands j which aUp become fcirrhous, and afterwards 

 cancerous. 



This cancerous matter does not feem to acquire its malignant 

 or contagious quality, till the cancer becomes an open ulcer ; 

 and the matter fecreted in it is thus expofed to the air. Then 

 it evidently becomes contagious, becaufe it not only produces 

 hectic fever, like common matter in ulcers open to the air, but 

 it alfo, as it becomes abforbed, fwells the lymphatic glands in its 

 vicinity ; as thofe of the axil] a, when the open cancer is on the 

 breaft. See Clafs II. i. 3. 



Hence exfeclion before the cancer is open is generally a cure ; 

 but after the matter has been expofed to the air, it is feldom 

 of fervice ; as the neighbouring lymphatic glands are already in- 

 feted. I have obferved feme of thde patients after the opera- 

 tion to have had difeafed livers, which might either have previ- 

 oufly exifted, or have been produced by the fear or anxiety at- 

 tending the operation. 



Erofion with arfenic, after the cancer is become an open ul- 

 cer, has generally no better effeft than exfeclion, but has been 

 fuccefjjful before ulceratioa. The bcft manner of ufmg arfenic,
