tially of a metallic plate placed upon the inner side of the thigh 

 over the vessel, having three holes at short intervals through which 

 screws passed, each having at one of their extremities a firm pad, 

 and at the other a projection to which a key was adapted, by means 

 of which pressure could be made upon the femoral artery at the dif- 

 ferent points. This metallic plate was secured over the artery by 

 means of broad straps attached to a sliding plate of steel, secured in 

 a metallic bar, applied longitudinally to the back of the limb. 



Soon after the adjustment of this instrument, it was ascertained 

 that the patient loosened the screw in the absence of his attendant. 

 He was now watched night and day for three days, by the end of 

 which time all pulsation in the tumour was entirely arrested. The 

 swelling gradually subsided to half its original size. The only in- 

 convenience experienced by the patient was a numbness of the limb, 

 upon the first removal of the instrument, but this soon left him, and 

 he was discharged cured on the 13th of April. 



The case of Dr. Watson was one of femoral aneurism, treated 

 also at the New York Hospital. The subject of it was an intempe- 

 rate Irish woman, aged 38. The tumour, which was hard and pain- 

 ful to the touch, had existed for a month, and extended from the 

 upper and inner third of the thigh to within a finger's breadth of 

 the internal condyle of the femur, and at the point of its greatest 

 circumference, reached from the inner border of the rectus muscle 

 to the middle of the outer side of the thigh. 



At midday, on the 23d of September, 1847, pressure was made by 

 means of two pads secured to circular straps over the artery, with 

 counter-compresses on the outer side of the thigh, the pressure pro- 

 duced being regulated by a screw which acted directly upon the 

 pads over the vessel. The first compress was fastened over the 

 artery just as it emerges from beneath Poupart's ligament, the 

 second, a short distance below it, and both were so arranged as par- 

 tially to control the circulation in the tumour, the pressure being 

 regulated by alternately tightening one compress and slackening the 

 other, in order to prevent abrasion of the integument. On the 24th 

 the patient was restless; on the 25th she complained greatly of 

 cramp and pain in the leg, which was much swollen, to relieve 

 which a roller was applied, and the limb elevated on a pillow. 



By the 26th ail pulsation had left the tumour. The upper com- 

 press was now removed — sixty-eight hours having elapsed from its 

 first application, and very slight pressure was kept up by means of 

 the lower one. No return of pulsation followed the removal of the
