594 The Limhs as a Whole, 



The posterior tibial vein at its upper part seems to have 

 been thrombosed during life. The anterior tibial artery is 

 somewhat contracted ; its coat thickened, and contains a few 

 calcareous particles. In the interior there was a loose clot 

 in many places. 



The discoloured gangrenous portion is separated from 

 the rest of the leg by a line of demarcation. The tissues 

 in the gangrenous part are soft and oily from degeneration,, 

 while those in the upper part are dry and free from oil and fat. 



This seems to have been a case of embolus of the artery 

 rather than of thrombosis. G. C. 3147.

11. 73. Moist Senile Gangrene of Foot — Separated.— 



Gangrenous foot of an adult — in spirit, illustrating the above. 



The sloughy condition of the specimen is well shown. It 

 is still discoloured, although much of the colour must have been 

 bleached by the spirit. The foot has separated at the ankle 

 joint. G. C. 2712.

11. 74. Moist Senile Gangrene of Hand and Forearm.— Left 



hand and forearm — in spirit, partially dissected to illustrate the 

 above. 



The patient, a woman aged 79 years, was an inmate of a workhouse. 

 The medical attendant's report was as follows : — 



"She had fatty degeneration of the heart's muscle, and extensive 

 atheromatous disease of blood-vessels, and occasionally had fits of an 

 e[>ileptic character, due, I think, to localised brain softening. Her last 

 illness dated from July 23rd, when she fell over the bed while asleep, and 

 sustained an injury to the left arm. The trouble began in the fingers, and 

 spread gradually to the hand and arm, assuming all the appearances of 

 moist gangrene. She was comatose two or three days before death, which 

 took place on 13th August 1888." The arm was decomposing and putrid 

 during life. 



The tissues in the gangrenous part are oily and soft from 

 decomposition.
