22 ON THE NATURE AND ACTION OF SNAKE-rOISON. 



5.20. Heart beating feebly, and its action jumping. 



5.30. Heart beating slowly. 



6.30. Heart beating a little quicker. 



7.30. Heart as before. 



8. Heart beating more slowly. 



8.30. Cardiac pulsations are very feeble. 



9.30. Very feeble and slow. 



The hour was now late; the rabbit was still completely 

 motionless, and its body felt cold to the touch. The artificial 

 respiration was therefore discontinued, although the cardiac 

 pulsations had not ceased. Life was evidently prolonged for 

 some hours in this case by artificial respiration. 



Experiment X. 



November 28th, 1872. — One-fifth of a drop of cobra-poison 

 (the first supply), diluted with about 2 cub. centims. of ^-per- 

 cent, salt, was injected into the external jugular of a rabbit, 



12.5. Injection made. 



12.20. The animal has been convulsed and paralysed. 

 Sensibility of the cornea has disappeared ; cannula placed in 

 trachea and artificial respiration commenced. Temperature, 

 100°. 



1.15. Temperature, 96°"3. Heart is beating vigorously. 



3.13. Heart is beating as before. 



3.20. In order to try if possible to quicken elimination, milk 

 was injected into the stomach, 



4.5. Heart is beating as well as ever. 



4.40. Heart still beating vigorously. Eespiration discontinued. 

 Death soon followed. In this case also life was prolonged by 

 artificial respiration.
