respiration is getting feeble. The animal seems quite conscious, and starts 

 if touched. 



2.4. It is now quite feeble. When the cornea is touched the reflex 

 action is less than before. 



2.5. No convulsions. Artificial respiration commenced. The rabbit, 

 wrapped in cotton, was placed in a double tin bath filled with warm 

 water. Temperature in rectum 98'8. 



2.11. Respiration discontinued for a space. 



2.12. Convulsive twitchings of legs begin. Natural respiration has ceased. 

 Artificial respiration resumed. Pupils contracted. Reflex action on 



irritation of the cornea has ceased. 



2.16. Since the artificial respiration has been resumed there have been 

 no more convulsive twitchings. 



2.55. The heart beats rapidly, but vigorously. 



Temperature 101. The bath being rather hot, its temperature was 

 lowered by a little cold water added to it. 



2.57. The animal passed a quantity of urine tinged with blood. 



3.5. Heart beats vigorously. 



3.15. The eyeballs are very prominent ; pupils normal. 



3.45. Heart beating well, but apparently not so vigorously as before. 

 Teperature 100-5. 



3.55. The bath getting cold ; a little hot water added to it. The heart 

 beating more vigorously than at 3.30. 



4.20. Heart beating well if any thing, more vigorously than before. 



4.40. Heart beats steadily, but apparently with less vigour. Tempera- 

 ture 100-2. 



5. Heart sometimes beats steadily 130-140 times per minute. Then 

 it gets feeble and intermits, and again beats steadily. 



5.5. Heart beats more freely. Added more warm water to the bath. 

 5.25. Heart beats rapidly but more feebly. 

 5.35. The same. 



6. Heart beating rapidly, perhaps rather more feebly. Temperature 

 maintained at 100 0< 5. 



6.10. Heart beating well and more vigorously. 



6.30. Heart beating well, rapidly but steadily. 



The attendant, being left alone, discontinued artificial respiration, and 

 the animal died. The fluctuations in the activity of the pulsations were, 

 in all probability, due to the more or less perfect maintenance of the arti- 

 ficial respiration. 



Experiment LXVIII. 



A small rabbit had two drops of diluted cobra-poison injected into the 

 jugular vein. In 30 seconds he was in convulsions, and in 60 seconds 

 was dead. 



The thorax was opened immediately ; the heart had ceased to beat, and 

 was firmly contracted.
