fingers, without a compress, upon the artery as it passes over the os 

 pubis, and the direction given to the assistants was to keep up this 

 amount of pressure as nearly continuously as possible." This treat- 

 ment was commenced at 3 o'clock P. M. No pain of consequence 

 was produced by it for five or six hours, and then it was not severe, 

 and was quieted by the eighth of a grain of morphia once or twice 

 repeated. About eight hours after the pressure was applied, the 

 temperature of the limb was diminished, and it appeared shrunken 

 in size. Upon removing the pressure from the artery at 11 o'clock 

 of the following day — twenty hours from the commencement of the 

 treatment, the tumour was found to have diminished very little, if 

 at all, and pulsated as strongly as before ; but the tibial arteries 

 could not be felt. The treatment was continued. Upon examining 

 the parts the next morning, forty hours after the treatment was 

 begun, the tumour was found to be nearly one-third less in size, firm 

 and unyielding on pressure, and entirely without pulsation. All 

 treatment was then discontinued. The femoral artery pulsated with 

 its usual strength in the groin, and distinctly as far as its passage 

 through the tendon of the adductor muscles. Between this point 

 and the tumour it could not be felt. Several of the anastomosing 

 arteries, especially one upon the inside of the limb, could be dis- 

 tinctly traced passing over the knee, pulsating strongly, and en- 

 larged in size. From that time to the present — a period of more 

 than four months — no change has taken place in the limb, except 

 that the tumour has gradually diminished, so as now to be scarcely 

 discoverable, and that the leg, which was at first cold and weak, has 

 nearly regained its natural temperature and strength. 



Within the past year another instance has been reported, in 

 which a ligature was placed upon the common iliac artery for aneu- 

 rism, by Dr. Lyon, of England. The bold and successful precedent 

 for this, it will be remembered, was first done by Dr. Mott, of New 

 York, in 1827. In 1812 the common iliac was tied, in a case of 

 gun-shot wound, by Dr. Gibson. The patient lived thirteen days 

 after the operation. Since this period, the case just alluded to 

 makes the eighteenth in which the operation has been performed, of 

 which eight have proved successful, and ten have died. The aim of 

 this Report being to show results, rather than to give the details of 

 operative procedures, particularly when not done among us, a bare 

 mention of this fact will suffice. In connection with it, it may be 

 interesting to notice the final issue of the instance in which this 

 artery was last tied in this country. The operation was done by
