lower trunk of the divided artery ; yet the velocity of its current was so much 

 abated, that it seemed like blood flowing from a vein ; I left the wound with a 

 digestive, and the part without hard bandage; it being now 3 weeks since, I 

 hear the wound is almost cicatrized. — The learned Dr. Harris was present at 

 tlie other operation, by which the communications of the large trunks of the 

 arteries of the arm were very evident ; it was a boy about 8 years of age, who 

 came to town with an aneurism of the left arm, after bleeding 6 weeks before: 

 the tumour was indeed very large in proportion to so small an arm ; after laying 

 the aneurism or tumour bare, and making a ligature on the superior trunk of 

 the artery (at * in the fig. — ) I found, on loosening the compass on the supe- 

 rior trunk of the artery, very little abatement of the pulsation of the aneurism ; 

 I then passed a ligature in like manner on the trunk of the artery below the 

 tumour; but still the pulsation continued, though much abated ; I then disco- 

 vered another trunk of the artery; arising from the lower part of the tumour, 

 on which also I made another ligature, and the pulsation was then taken of^'; 

 however on cutting off the surface of the cystis, or dilated artery, and clearing 

 it of the coagulated blood, there still poured out some fresh blood, which was 

 soon stopped with a common astringent ; I left the part without any other liga- 

 ture or hard bandage. It is now 18 days since the operation, the ligatures on 

 the arteries are all come oflT, and the pulsation of the artery of the wrist begins 

 to be very manifest, nor does any symptom appear that threatens mischance — 15
