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 Paradoxure (Nandinia binotata). In 
the case of the Paradoxure the affection of the callous pads is in an 
early stage, for the ulcers, one on each foot, are as yet shallow (fig. 2). 
Perforating ulcers (w) in an early stage affecting the feet of a Paradoxure, Nan- 
dinia binotata, secondary to sclerosis of the spinal cord. The ulcers 
were perfectly symmetrical on the fore and hind feet. 
F, the fore, and H, the hind foot. 
The most remarkable feature in the specimen is the perfect symmetry 
observed in the ulcers; in each fore foot the 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
