REPARATOKY INFLAMMATIOX IN ARTERIES. 3 



do SO, the cases which may be cited in proof thereof will be 

 extremely rare." 



Mr. Sharp, a few^ years later (Operations of Surgery, 1139), 

 entertained and taught principles goveruiug the checking of 

 hemorrhage very similar to those advanced by the last-named 

 investigator. 



M. Pouteau is the next person Ave find publishing the results 

 of investigations relating to tlie healing of bloodvessels (Me- 

 langes de Chirurgie, 1760). 



He concluded, " That when an arterj- is divided, a coagulum 

 does not alwaj's form ; that the retraction of the arterj- has not 

 3'et been demonstrated ; that the retraction of the walls is not 

 more effectual for the arrest of hemorrhage than is the presence 

 of a clot ; that the presence of a clot is only a very weak and 

 subsidiary means toward that end ; tliat the infiltration and 

 swelling of the cellular membrane at the circumference of the 

 cut extremity of the artery offer the chief obstruction to the 

 bleeding; that by exciting and aiding in a more rapid and 

 general induration of that membrane, the use of the li<>-ature is 

 valuable for the arrest of hemorrhage." 



The name of Kirkland appears next upon the list of those 

 who have endeavored by a series of observations to penetrate 

 the waj's which nature adopts for the cure of a wounded vessel 

 (Essay on the Methods of Suppressing Hemorrhages from 

 Divided Arteries, 1763). 



His opinions raa^' be formulated as follows: — 



The hemorrhage from a verv considerable artery is easily 

 and effectually suppressed by merel}- making a perpendicular 

 pressure upon the end of the vessel for a few minutes. 



The bleeding is not suppressed by congealed blood, but bj' 

 the vessel being quite closely contracted for near an inch or 

 more from its extremity. 



Interruption of the ])assngc of the blood for a wliilc is all 

 that is required from art.
