upon his feet with difficulty, his legs being too weak to hold him up. 

 Some of the time when standing he would tremble, and at times 

 he would place his legs wide apart as if to keep from falling over. 

 This was particularly noticeable as he walked down hill. Some- 

 times in walking he would stagger to one side or the other. It was 

 noticed that he urinated quite frequently but the quantity was not 

 great. At 10.30 he seemed to be stronger upon his legs and no 

 marked change was noticed during the rest of the day. Several 

 times he was found lying down but was able to get up without much 

 difficulty. 



As showing his weakness it was noticed that when he swung his 

 head around to brush off flies the movement would cause a loss of 

 balance so that he would stagger and almost fall. 



Plate X, figures 1, 2, 3, and 4, show some of the attitudes assumed 

 by him during the day. When first seen on the morning of August 

 15, between 6 and 7 o'clock, his condition did not seem to be changed 

 from that noticed on the preceding day. He was upon his feet and 

 moving about a little. At 8.15 he seemed much weaker. He was 

 down and made no effort to get up. Even with assistance, he was 

 unable to raise the fore part of the body. Plate X, figures 5 and 6, 

 show his attitude at this time; in figure 5 he was trying to hold 

 himself upon his feet while in figure 6 he was falling again. At 

 8.25 he was given a drench of potassium permanganate. His heart 

 action was very weak at this time and it was with great difficulty 

 that his pulse could be detected. Respiration seemed normal, al- 

 though his breathing apparently caused pain. At 8.30 he was given 

 subcutaneously 1 grain of atropin dissolved in camphor water. 

 A little after this he tried to get up but was unable. He could 

 not get his forequarters off the ground, but did succeed in moving 

 himself around. Plate XI, figure 1, shows him just as he had fallen 

 back- after an attempt to get upon his feet. During the rest of 

 the day he made several attempts to get up but was generally 

 unable to raise his hindquarters from the ground. It was evident 

 that he was in constant pain and this forced him to attempt to 

 change his position. At 9.55 a. m. his pulse was about 95, his 

 respiration 36. The pupils were very much dilated from this time 

 on, probably from the influence of the atropin. There were spas- 

 modic contractions of the abdominal muscles. 



Plate XI, figure 2, shows the animal attempting to get up at 

 9.10; figure 3 shows him at 9.35 when he was attempting without 

 success to get up. The abdominal pain was apparently very severe. 

 At 10.30 he was given subcutaneously 25 grains of caffein sodio- 

 benzoate. At 10.40 his temperature was 102.4° F. Plate XI, figure 

 4, shows his attitude at 10 a. m. and figure 5 shows him at 12.05, noon. 

 At 2.45 he seemed weaker than at any preceding time and the pulse 

 was hardly perceptible. He was given 1 grain of atropin in cam-
