temperature greater than in a normal animal, the morning tem- 
perature being very low (see fig. 10). On July 17 it was turned into 
pasture to graze, but was brought in again July 19 and given feedings 
of oak brush. July 20 it was returned to pasture and brought into 
the corral on July 27. At this time it was very weak and the feces 
were composed largely of bloody mucus. It was given 500 cubic 
centimeters of raw linseed oil. On July 28 its eyes were sunken, and 
in the afternoon its pulse became almost imperceptible. On the 
morning of July 29 it was lying upon its side, groaning, pulse 
imperceptible, breathing with difficulty, and died at 11.30 a. m. 
At the autopsy deep congestion was found in the duodenum,

upon oak exclusively. 
No. 765 was fed from July 10 to July 26. On July 21 it was 
noted that the feces were hard and bloody, and from this time the 
animal was very much constipated and showed marked depression. 
The coat was rough and the nose dry. From the beginning of the 
feeding it progressively lost weight, as shown in figure 11. There 
was nothing abnormal about the pulse and respiration rates. The 
difference between morning and afternoon temperature was rather
