canal, the cord was found soft and almost diffluent. By careful 

 hardening and manipulation, sections were obtained from the cord 

 and submitted to the microscope. It exhibited a most marked 

 degree of sclerosis. This was also seen in the nerves of the affected 

 limb. The animal was supposed to be about seven years of age, 

 and had been paralyzed for some time before it died. The specimen 

 was shown to a number of experts, who were unanimous as to the 

 nature of the affection, viz. perforating ulcer, with sclerosis of the 

 cord and nerves. I then ventured the opinion that more cases would 

 come to hand. A few weeks later a second specimen came under 

 my observation, also in a Civet Cat ; and, lastly, a most interesting 

 example in the Two-spotted Paradoxnre {Nandinia binotata). In 

 the case of the Paradoxure the affection of the callous pads is ia an 

 early stage, for the ulcers, one on each foot, are as yet shallow (tig. 2).

 were perfectly syitimetrical on the fore and hind feet.

The most remarkable feature in the specimen is the perfect symmetry 

 observed in the ulcers ; in each fore foot tlie position and shape of 

 the sores correspond exactly, and this is also to be observed in the 

 hind feet. In this case only the lumbar and anterior portion of the 

 spinal cord could be examined ; for, after the animal died, its com- 

 panion, much to my annoyance, had eaten the middle portion of its
