This sheep, a heahhy eAve, weighing 72 pounds, Avas clepriAed of 

 food on March 21 and 22, 1914, and on INIarch 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

At 10.25 a. m., 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 giA^en 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-

 to be very much better. Figure 3 sIioaa's the condition at 1.15 p. m.
