ferted beneath the cuticle or fwallowed into the ftomach ; that 

 is, as they were formed by certain morbid adlions of the ex- 

 tremities of the vefiels, they have the power to excite fimilar 

 morbid aftions in the extremities of other veffels, to which they 

 are applied ; and thefe by fympathy, or aflbciations of morion, 

 excite fimilar morbid actions in diftant parts of the fyftem, with- 

 out entering the circulation ; and hence the blood of a patient in 

 the fmall-pox will not give that difeafe by inoculation to others. 

 When the new fibres or veflels become again abforbed into 

 the circularion, the inflammation ceafes ; which is promoted, 

 after fufficient evacuation, by external (limulants and bandages : 

 but where the aft ion of the veflels is very great, a mortification 

 of the part is liable to enfue, owing to the exhauftion of fenfori- 

 al power ; which however occurs in weak people without much 

 pain, and without very violent previous inflammation ; and, like 

 partial paralyfis, may be efteemed one mode of natural death 

 of old people, a part dying before the whole.
