PLATE 2 
A and B.—Partial recovery of cat No. 11 (October 14,1920) from stage shown 
in Plate 1. It has a slight weakness of the fore legs, a greater weakness of the 
hind legs, and the quick step of the multiple neuritis type of paralysis. (Nega¬ 
tive exposed for one-fiftieth of a second.) 
C and D.—Unusual form of rapid locomotion shown by cat No. 11 (October 
14,1920). The back is arched and the tail is used as an aid in locomotion. (Nega¬ 
tive exposed for one-fiftieth of a second.) 
a and b.—(a) Enlarged hypertrophied and dilated heart of cat No. 11, and 
(b) heart of cat No. 19 (control animal). The large heart (a) weighed 12.35 gm. 
The net body weight df cat No. 11, which was about 32 weeks old, was 1,475 gm., 
exclusive of the serous exudate (215 gm.). Its previous maximum body weight 
was 1,890 gm. The body weight of cat No. 19, about 29 weeks old, was 2,405 gm, 
and the weight of its heart was 6.1 gm. The weight of the enlarged heart was 
twice that of the heart of a normal cat weighing 1,465 gm. The enlarged heart 
has much less epicardial fat than the smaller one.
