4 THE TOXER LECTURES. 



Gooch (Chirurgical Works, 1766) turned his attention only 

 a year or two later to tlie sul)ject before us. 



Mr. White (Cases in Surgery) agreed with Pouteau, Kirk- 

 land, and Gooch in rejecting Petit's theory of a coagulum as 

 not at all probable. He concluded that the formation of a 

 coagulum is only incidental, and is of no use whatever except 

 under particular circumstances. 



Hunter believed in the adhesive inflammation of all the 

 tissues of the vessels. He considered that the clot adheres 

 to the walls, and undergoes organization. 



John Bell (Principles of Surgery, 1801) also ranged himself 

 on the side of those who opposed the views of Petit and 

 Morand. He thought that hemorrhage is alwaj^s permanently 

 prevented by the changes which take place in the surrounding 

 cellular tissue, and by adhesive inflammation of the' arterial 

 walls themselves. 



J. Thomson, of Edinburgh, made some observations upon 

 the effect of ligation. 



The next to be mentioned in chronological order is the classic 

 work of J. F. D. Jones, M.D. (A treatise on the process em- 

 ployed by nature in suppressing the hemorrhage from divided 

 and punctured arteries, and on the use of the ligature, etc., 

 1805). The completeness of this man's experiments, and the 

 apparent soundness of his judgment upon the principles to be 

 deduced from his results, succeeded in settling, at least for a 

 lengthened period, the much-vexed question which he set him- 

 self to solve. Indeed, such have been the closeness and accu- 

 racy of his inA'Cstigations that, even to-day, his excellent 

 monograph remains admittedly the authority upon the means 

 which nature adopts for the suppression of hemorrhage. The 

 occasion is taken here to acknowledge our indebtedness to his 

 paper for much of this history. 



With respect to spontaneous arrest of hemorrhage from 

 divided vessels, Jones states that for the reason that the for-
