.224 ESSAYS AND OBSERVATIONS 



From the cafe of this man, and that of 

 John Parker, we may conclude, that the 

 arterious fyftem is fometimes univerfally 

 difeafed, though we neither as yet know 

 how this happens, or can alTign any caufe 

 for fuch a diforder ; and, from thefe 

 cafes, we may judge how doubtful the 

 fuccefs of any operation muft be, that is 

 attempted for the cure of any true aneu- 

 rifm in the extremities, which comes 

 ^vithout any external injury done to the 

 part. 



Are aneurifms become a more fre- 

 iquent diforder than formerly, or do phy- 

 ficians and furgeons inquire more minute- 

 ly into the nature ^nd caufes of difeafes, 

 and infpetl more narrowly into dead bo- 

 dies than in former days ? The latter I 

 fliould fuppofe to he the cafe, from the 

 aneurifms which I have feen, which were 

 all in people in a low rank of life, who, 

 in former times, had not fo frequent op- 

 portunities of confulting phyficians and 

 furgeons of experience, or of being recei- 

 ved into public hofpitals.
