And fvom hence it appears, why weak people are more 

 fubject to mortification than ftrong ones, and why 

 in weak perfons lefs pain will produce mortifica- 

 tion, namely, becaufe the fenibrial power is fooner 

 exhaufted by any excels of activity* I remember 

 feeing a gentleman who had the preceding day tra- 

 velled tw r o ftages in a chaife with what he termed 

 a bearable pain in his bowels ; which when I faw 

 him had ceafed rather fuddenly, and without a paf- 

 age through him ; his pulfe was then weak, though

 of this fenfation conjointly w ith the irritation : which 

 motions conftitute inflammation. If the fever be 

 attended with a flrong pulfe, as in pkurify, or rheu- 

 rnatifm, it is termed fynocha fenfitiva, or fenfuive 

 fever with ftrong pulfe ; which is ufually termed in- 

 flammatory fever. If it be attended with weak 

 pulfe, it is termed typhus feniitivus, or fenfitive. fever 

 with weak pulfe, or typhus gravior, or putrid ma- 

 lignant fever. 



The fynocha fenfitiva, or fenfitive fever with 

 ftrong pulfe, is generally attended with fome topical 

 inflammation, as in peripneumony, hepatitis, and is-
