liQit.-ie. 



Post-mortan examination, Xovembcr A. — SJcin : Almost universally scarlet, passing to darli 

 purple on ears, belly, and hoclcs. Inner sides of tlio fore-arms and tliighs have the skin 

 •wMte, but blotched ^vith indelible pmple spots one-half to one line iu breadth. Many 

 of these spots have a dark red or purple areola, with a firm black central scab or 

 slough, evidently resulting from extravasation into the cuticle and supcrhcial layers 

 of the true skin. A section made perpendicularly to the surface shows much reducsfi 

 from blocked branching blood-vessels, especially around the hair follicles, and numer- 

 ous minute spots of blood extravasations. 



The snout is of uniform dark red, but with deeper purple spota ineffaceable by 

 pressure. 



Margin of the arms deep purple, almost black.
