212 PLEURISY, &c. 



" rify is an inflammation of the pleura-^' but, 

 as " no ghoft need come from the grave to 

 " tell us that" we will go a little farther, 

 and, inftead of diverfifying and mutilating the 

 fymptoms to form a deceptive appearance of' 

 two diftina difeafes, 1 (hall clearly prove them 

 to be not only of the fame family, but very 

 nearly related ; for, as the pleura is in the me- 

 dical world univerfally known to be the mem- 

 brane immediately covering the lungs, every 

 reader may inftantly form his own judgment 

 whether the latter can become the principal 

 feat of inflammation without tht pleura's be- 

 ing proportionally affeded by the diftention. 

 I have not the lead doubt but this thefts will 

 fufficiently eftablifti its own weight to prevent 

 a diverfity of opinions. 



To exclude occafion for more medical or 

 anatomical definitions than are abfolutely un- 

 avoidable, it muft fuffice to fay the d.ftinc- 

 tion between the difeafes are too nice (in this 

 animal) for certain difcrimination; either M- 

 plays fymptoms common to both ; and, as the 

 treatment is exaftly fimilar in each, no incon- 

 venience can arife from not decifively fixing it 

 upon one or the other, as in general they are 

 *^ both
