Case No. 4 A ewe weighing 65 pounds was fed 1 pounds of green 

 material at 2 :45 p. m. At 8 : 40 p. m. she was sick. When she 

 attempted to walk it was with a staggering motion. By 8 o 'clock next 

 morning she was down on her side, her head drawn far back, eyes 

 staring and bleared, the pupils dilated. At times she would grind her 

 teeth and champ her jaws. Most of the time there was a rapid running 

 movement of the legs, followed by spells when they would be extended 

 and extremely rigid. This series of movements continued until noon. 

 By 2 :30 p. m. the spasms had become weaker and of shorter duration, 

 and the intervals between them were longer. At 3 : 30 p. m. the 

 spasms were very weak, lasting for an instant or two and recurring 

 about every ten minutes. The animal's temperature was then 105.6. 

 At 4 p. m. the spasms increased in violence, became more severe and 

 were accompanied by bleating grunts. At 4 : 15 p. m. there was a 

 severe, spasm lasting about five minutes, accompanied by champing of 

 the jaws, grinding of the teeth, and foaming at the mouth. The head 

 was frequently drawn far back. These severe spasms continued about 

 every two minutes until shortly before death, which occurred at 

 4 : 45 p. m. 



The autopsy showed the spleen slightly mushy, the liver soft and 

 friable ; all other organs appeared normal. (Brain not examined.)

 noticeable in the hind legs. At 8 a. m. the next day she was down and 

 unable to get up, lying flat on her side with legs stretched out. Fre- 

 quently she would chew at the bedding, and would champ her jaws 

 most of the time. A peculiar trembling of the nose and lips was notice- 

 able. At 9 : 30 p. m. she was in the same condition, groaning as if in 

 pain, kicking the hind legs and frothing at the mouth. Her tempera- 

 ture at 1 : 30 p. m. was 103. She was in this condition until. 3 p. m., 

 when she died.

 noon the animal was sick, walking with an unsteady gait. It con- 

 tinued to get worse during the afternoon. Next morning it was unable 

 to get up and had convulsions when disturbed. It soon fell over on its 

 side and had running movements with its legs. It remained in this 

 condition until death, which took place about 10 a. m. 



The autopsy at 11 a. m. showed the following conditions: There 

 was an acute cloudy swelling of the right kidney. The left was affected 

 by a chronic disease not caused by poisoning. The liver was fri- 

 able and highly reddened ; blood flowed from cut surface. Some of the 

 lymph glands were hemorrhagic. The brain showed marked congestion 

 of the meninges, especially over the cerebellum and the anterior por- 

 tions of the cerebrum. Many minute pin-point hemorrhages were 

 found in the gray matter of the brain. These were located in the corpus 

 striatum, corpus callosum, medulla, and medullary portions of the 

 cerebrum.
