to a quack who was for a time much resorted to, in this part of 

 the country. 



Another method of using charcoal-powder is by mixing it with 

 boiling oil, to the consistence of common paint; and to soak a 

 piece of flannel with this, and cover the ulcer; and daily to 

 shove or thrust this off by applying the edge of another piece of 

 flannel, soaked with the oil and charcoal, to the edge of that upon 

 the ulcer, 'so as to change them without the possibility of letting 

 any air come into contact with the cancerous sore. 



17. Jlrthrocele. Swelling of the joints seems to have its remote 

 cause in the softness of the bones, for they could not swell unless 

 they were previously softened, see Class I. 2. 2. 12. The epiphy- 

 ses* or ends of the bones, being naturally of a looser texture, are 

 most liable to this disease, and perhaps the cartilages and capsu- 

 lar ligaments may also become inflamed and swelled along with 

 the heads of the bones. This malady is liable to distort the fin- 



ters and knees, and is usually called gout or rheumatism; the 

 )rmer of which is liable to disable the fingers by chalk-stones, 

 and thence to have somewhat a similar appearance. But the 

 arthrocele, or swelling of the joints, affects people who have not 

 been intemperate in the use of fermented or spirituous liquors; 

 or who have not previously had a regular gout in their feet; and 

 in both these circumstances differs from the gout. Nor does 

 it accord with the inflammatory rheumatism, as it is not attended 

 with fever, and because the tumours of the joints never entirely 

 subside. The pain or sensibility which the bones acquire when 

 they are inflamed, may be owing to the new vessels, which shoot 

 in them in their soft state, as well as to the distention of the old 

 ones. 



M. M. Half a grain of opium twice a day, gradually increased 

 to a grain, but not further, for many months. Thirty grains of 

 powder of bark twice a day for many months. Ten grains of 

 bon-ashes, or calcined hartshorn, twice a day, with decoction 

 of madder? Soda phosphorata? 



18. Jlrtliropuosis. Joint-evil. This differs from the former, 

 as that never suppurates; these ulcers of the joints are generally 

 esteemed to arise from scrofula; but as scrofula is a disease of the 

 lymphatic or absorbent system, and this consists in the suppuration 

 of the membranes, or glands, or cartilages, about the joints, there 

 does not seem a sufficient analogy to authorize their arrangement 

 under the same name. 



The white swelling of the knee, when it suppurates, comes 

 under this species, with variety of other ulcers, attended with ca- 

 rious bones. 



19. Caries ossium, or Necrosis ossium. A caries of the bones
