This sheep, a healthy ewe, weighing 72 pounds, was deprived of 

 food on March 21 and 22, 1914, and on March 23 an attempt was 

 made to make her eat the Chrosperma, which had been sent from 

 North Carolina and had been kept in cold storage. As she would 

 not take it, food was withheld for 24 hours longer. March 24, at 

 11.35 a. m., 10 grams of Chrosperma tops in green rye were given. 

 At 11.41 a. m. another 10 grams mixed with rye were given. All this 

 material was eaten in the course of the afternoon. On the morning

of March 25 the watchman reported that the sheep had been sali- 

 vated during the night. She refused that morning to eat rye, but 

 otherwise seemed to be all right. 



At 10.25 a. m v March 25, 10 grams of the plant cut up fine 

 and mixed with corn, oats, and wheat was offered, but very little 

 was eaten, so that the material was fed by putting it directly 

 into the sheep's mouth. Another 10 grams was given at 11.05 a. m., 

 and a third 10 grams at 11.45 a. m. At 11.43 the ewe held her head 

 low and shook it from side to side as if nauseated. At 11.45 there 

 was distinct salivation, and at 12.05 vomiting. This condition of 

 illness, representing nausea, extreme discomfort, and weakness, con- 

 tinued until between 2 and 2.30 p. m., at which time the sheep seemed 

 to be very much better. Figure 3 shows the condition at 1.15 p. m. 



March 26, 9.40 a. m., the sheep was tying down, but when made to 

 get up staggered, licked her lips, and ground her teeth. She was
