shrunk, but its luiuen is still recognisable. The vessel wall 

 throughout its whole extent is infiltrated with calcareous 

 particles. The peroneal artery is likewise obliterated at its 

 upper part, but the clot seems more recent. Lower down the 

 condition of this vessel is similar to that of the posterior tibial 

 artery. The veins were found empty and are nowhere throm- 

 bosed. The anterior tibial artery is obliterated at its upper 

 part, while lower down its lumen is contracted and is in places 

 obliterated. The gangrenous and sloughing state of the fore- 

 part of the foot is well shown. The great toe was amputated 

 at a previous operation. G- C. 3377.

11. 72. Moist Senile Gangrene of the Foot and Leg-.— Lower 



part of a left leg and part of foot, blood-vessels dissected— in 

 spirit, illustrating the above. The forepart of the foot was 

 removed for convenience in mounting the specimen. 



The patient, a woman aged 68, had a history of gradually increasing 

 debility for a year, but with no premonitory symptoms of gangrene in the 

 limb. A severe pain in the left foot and lower half of the left leg occurred 

 suddenly, four months before her admission to the infirmary. Three days 

 later the foot grew cold. The pain increased, and discolouration of the 

 parts began. The latter gradually increased, but the pain subsided. 

 There was no known cause for the onset of the disease. The leg was 

 amputated, and the patient made a good recovery. 



The posterior tibial artery is completely blocked at its 

 upper part by a firm clot, which has apparently become adherent 

 to the walls. The blocking continues down to about where 

 the peroneal artery is given off. The continuation of the 

 posterior tibial artery was accidentally removed in dissecting the 

 specimen, but a small portion left at the upper end shows the 

 vessel to have been greatly contracted. Its coat is thin, and only 

 a few particles of lime salts can be felt upon it. The peroneal 

 artery, although the larger of the two, is small and contracted, 

 and its interior is occupied by a fine clot. Its coat also is 

 only slightly thickened, and contains but few calcareous particles.
