22 THE TOXER LECTURES. 



at least once, and several of tliem, such as 24, 48, 94 bours, 

 and 10 and 15 days, were repeated two or three times and 

 often er. 



A second aeries w^as begun, but owing to pressure of other 

 engagements was not entirely completed. This series was in- 

 tended to suppl}' as full a number of preparations as the first. 

 The procedure followed in the preparation of this series con- 

 sisted in a slight modification of the ordinary manner of per- 

 forming ligation : the ligature was applied in the continuity of 

 the vessel in the usual manner ; immediately afterward the 

 vessel was compressed an eighth of an inch above the point 

 of ligature, by means of an ordinary- pair of dressing forceps, 

 so as to moderately rub together opposite points of the inner 

 surface of the internal membrane of the vessel, and thus pro- 

 duce at these points a sufficient irritation, at the same time 

 avoiding if possible any rupture of the inner tunic. A num- 

 ber of preparations from this were obtained, varying from three 

 to ten days. 



The third series consisted of a limited number of prepara- 

 tions to show the method of healing after limited torsion. 



A fourth series was obtained, the number of preparations 

 also being much smaller than the first. They were intended to 

 supply a full series for the satisfactory study of the process 

 of healing after acupressure. In performing acupressure, the 

 procedures known as the third and fourtii methods were 

 adopted — the third being done in the continuity, and the 

 fourth after the division of the vessel. The needle was allowed 

 to remain in the tissue until the specimens were hardened for 

 examination. I may say here that a fifth series was also com- 

 menced, wherein specimens were to be obtained to show the 

 results following a mere occlusion of an artery in continuity, by 

 moderate pressure produced by the inclusion of the artery for 

 a few hours between the arms of a small serre-fine. The ex-
