galloides per hundredweight of animal; August 8, 0.22 pound; Au- 

 gust 13, 0.212 pound, and August 17, 0.291 pound. None of these 

 feedings took effect. 



No. 750 also was fed four times. It was a steer that was locoed in 

 1917, but under continued treatment was practically cured, although 

 not quite in full flesh. The animal would be considered in fair con- 

 dition. On August 22 this animal received 0.22 pound per hundred- 

 weight of animal, which produced no effect. On August 25 it re- 

 ceived 0.626 pound per hundredweight of animal, again with no re- 

 sult. In the feeding of August 22 the material was eaten within 1 

 hours; in the feeding of August 25 it was eaten in about 2^ hours. 

 On August 26 the animal received 0.848 pound per hundredweight 

 of animal, but unfortunately no note was made as to whether all was 

 consumed. No symptoms appeared during the day. On the next day, 

 however, August 27, at 9.13 a. m., it was noticed that the muscles of 

 the fore legs and the neck were quivering in an abnormal manner. 



At 12.01 noon the animal fell upon its stomach, throwing the head 

 back and kicking spasmodically with its fore legs. It then lay upon 

 its belly with the forefeet doubled under the thorax and hind legs 

 stretched out, in a position as shown in Plate YI, figure 2. Figure 1 

 shows the animal just before it fell. It then got up and moved about, 

 staggering and trembling, with its hind legs far apart. At 12.10 it 

 was found moving in an unsteady way with shoulders twitching 

 violently and breathing with grunts. Saliva was dripping from its 

 mouth. Figure 3 shows the attitude at that time. It moved about 

 in a weak way, sometimes turning toward the right, and soon went 

 down again. Figures 4, 5, and 6 show the attitudes which it assumed 

 while attempting to stand. At 12.35 it went down, pushing forward 

 with great violence. Plate VIa, figure 1, shows its attitude as it came 

 down upon the ground. It turned over upon its left side, then back 

 upon its belly with the hind legs extended, but at 12.37 it was again 

 on its feet. Figure 2 shows the animal on its feet again at 12.40. 

 Figure 3 shows how it attempted to move rapidly and had difficulty 

 in maintaining itself. At 12.44 (fig. 4) it started to run and went 

 against the wall of the corral, fell down upon the right side with legs 

 stiffly extended, but rose in a few seconds, and at 12.45 was down 

 again, but at 12.46 was on its feet. At 12.50 it fell, rolled over on its 

 stomach, and then dragged itself along, in its attempts to rise. This 

 position is shown very- clearly in figure 5. Figure 6 shows its posi- 

 tion at 12.52 p. m. These movements were repeated again and again. 

 It ordinarily remained on its feet not more than 10 or 15 minutes at 

 a time. 



At 1.35 p. m., however, the animal seemed quite strong and when 

 made to run around the corral for two or three minutes did not fall, 

 although it still staggered. At 1.57 after being run about it ran into
