22'. It can no longer walk. 



23'. It has sunk down and lies flat on the table, leaning 

 rather to one side. Respirations are deep. There are occasional 

 twitches of the legs. 



25'. Cornea is sensitive. Occasional convulsive stretches. 



27'. Cornea almost insensible. Respiratory movement of 

 nostrils continues. 



28'. Cornea completely insensible. Post-mortem examination 

 made immediately. The muscles of the abdomen were dark- 

 coloured. Peristaltic movements of the intestines occurred 

 when the abdominal cavity was opened. The heart was dark 

 and slightly dilated ; all its cavities were contracting, though 

 feebly. There were three beats of the auricles to each one of 

 the ventricles. Irritation of the nerves in the pelvis caused 

 contractions of the legs. 



35' after injection. The heart is still feebly contracting.
