11. 78. Gangrene from Frost Bite. — Forepart of foot i 

 which the toes have been killed by exposure to cold— in spirit. 



The line of separation, formed by ulceration, is complete 

 in the skin, and is in progress in the deeper tissues. Some 

 portions of the extensor tendons still remain on the dorsum. 

 The metatarso-phalangeal joint of the great toe is exposed, and 

 the head of the first metatarsal bone is bare, and has probably 

 been in process of separation. The toes are apparently but 

 little changed. They had probably been killed outright, and 

 had not had time to shrivel and dry up. G. C. 225. 



11. 79. Gang-rene from Burn. — Forefinger injected and in 

 spirit, illustrating the above. 



From an old man who had fallen into the fire and burned his hanil 

 severely. 



The end of the fiuger is gangrenous, and the parts behind,, 

 which were living, have inflamed and ulcerated, and have 

 thus formed a line of demarcation. G. C. 2861.

11. 80. Gang-rene from Acute Septic Poisoning-. — Little 



finger — in spirit, illustrating the above. 



From the hand of a workman, aged 50, who had received a severe 

 cut of his thumb. The wound having become septic, inflammation spread 

 over the whole hand and up the forearm, and ended in extensive suppura- 

 tion and sloughing, with gangrene of this finger. It became shrivelled 

 and dry before it was removed. 



The ligaments at the meta-carpo phalangeal joint had been 

 destroyed. Granulations have eroded the surface of the 

 proximal end of the first phalanx. G. C. 3156.
