Dry Senile Gangrene. 591 



The fingers have been gangrenous in each case from the 

 proximal end of the second phalanx onwards. A line of 

 demarcation has formed, and the process of separation has been 

 in progress. The arteries have been injected, and some colour- 

 ing matter can be seen in the cross section of both the radial 

 and the ulnar artery. G. C. 95. 



11. 68. Dry Senile Gangrene of Fingcers.— Left hand — 



injected and in spirit, illustrating the above. 



Portions of the fingers and of the thumb have been 

 gangrenous. The distal ends of the second phalanges of the 

 fingers and the shrivelled end of the thumb project from the 

 soft parts. 



A line of demarcation has formed upon the soft parts, but 

 the bones had evidently not had time to separate. The end of 

 the thumb was evidently about to separate at the joint. The 

 injection has entered freely into the proximal ends of the 

 fingers. G. C. 96. 



11. 69. Dry Senile Gangrene of Hand.— Half-closed right 



hand, dried and varnished, illustrating the above. 



It is mummified, and of a brownish black colour.

11. 70. Advancing- Moist Senile Gang-rene of Foot.— A left 

 leg and foot — dissected, and in spirit, illustrating the above. 



The patient, a woman aged 62, was admitted to Mr Miller's Ward , 

 Royal Infirmary, Edinburgh, on 4th November 1889, suffering from moist 

 gangrene of the left great toe which was advancing up the foot. A month 

 before, while paring the great toe nail of the left foot, she had accidentally 

 cut the toe. The wound inflamed and suppurated. She had severe 

 pain in the foot, which was treated without benefit by poultices. After 

 three weeks the pain gradually diminished and disappeared. The foot, 

 however, got cold and black. On November 7th the leg was amputated 

 above the knee, and on the 9th she died.
