PLATE 1 
A. —Early stage of paralysis of fore legs, with the inward curl. The legs become 
crossed when the animal is raised. 
B. —Unequal paralysis of fore legs. This position was often assumed as the 
cat walked. 
C. —Double-jointed effect often seen as the cat walked. 
D. —Spastic paralysis of unequal degree in hind legs of cat No. 11 (September 
22, 1920). The tail was completely extended. Locomotion was accomplished 
by the fore legs, the buttocks and abdomen being dragged on the floor. Rabbits 
also show this type of paralysis. In earlier stages, paralysis was of a more 
flaccid type.
