 a man who is drunk. 



Experiment LX. 



August 29th, 1873. — A cannula was placed in the trachea of 

 a cat about 5.30 p.m. 



5.35. One decigram of dried cobra-poison, dissolved in 2 c.c. 

 of water, was injected into the peritoneal cavity. 



5.39. The animal lies on its side breathing very rapidly and 

 wagging its tail. Eises, sits with head erect and mouth widely 

 open. 



5.45. The respiratory movements are very rapid and shallow, 

 with occasional deep ones. The animal sits up. Eespirations 

 240 per minute. Pulse 148 per minute. 



G.3. The animal was lying down and occasionally rising. Is 

 now lying down. The respiratory movements have an extra- 

 ordinary vermicular character. Dr. Sanderson ascertained by 

 palpation that this is due to the diaphragm contracting before 

 the thoracic walls expand. 



6.7. The respirations are feeble, with occasional deep ones. 

 The cat walks quite well. The bowels act. 



6.20. Bowels act again. Tries to vomit several times. 



6.37. The cat lay on its side, and stretched itself once or 

 twice in a sort of convulsive manner. 



6.41. Lies quietly. When the cornea is touched or poked 

 with a pointed instrument, or when the finger is rubbed over 

 it, the eyelids do not close, nor does the animal give any sign 

 of feeling. When the hind legs are struck, it moves its fore 

 legs very faintly. Eespiration is quite i-egular and apparently 

 normal. The end of the tail gently moves from side to side. 

 When the inside of the ear is tickled the animal shakes its 

 head. It took a deep breath, and moved its liead voluntarily. 

 The pupil is much contracted. When tlie arms are irritated by 

 a sharp stick the animal draws its body slightly together. 

 A minute or two afterwards it moved its tail fi'om side to side 

 several times voluntarily. The animal was lying on its side. 

 Lifted it up and laid it on its belly with its feet under it. It 

 rose up and walked several steps. 



6.45. The cat again rises and walks, but staggeringly. It
