Experiment DCXIII. March 19. Temperature 18°. Terrier bitch 

 weighing 9 kilos. 



2:25. Tube placed in trachea; vaginal temperature 38°. 



2:32. Caused to breathe into a bag containing 40 liters of air with 

 89.4% of oxygen. 



Respirations extremely rapid. 



2:43. Drew from the carotid 25 cc. of moderately red blood .... A 



100 respirations, pulse 108, temperature 37.5°. 



3:10. Took sample of air from the bag .... a 



3:13. Drew 25 cc. of blood . . . . B 



3:20. Respiration 36; pulse 76; temperature 37°. 



3:38. Respiration 36; pulse 72, irregular; temperature 36.8°, urine; 

 sample of air from the bag . . . . b 



3:48. Temperature 35.9°. 



4 o'clock. Respiration 36; a cardiometer placed in the carotid 

 oscillates from 11.5 cm. to 19 cm. 



4:10. Temperature 35.2°; took sample of air from the bag . . . . c 



4: 18. 25 cc. of blood . . . . D 



4:30. Temperature 34.5°; legs insensible, eye still sensitive; respi- 

 ration 56; pulse 72. 



4:59. Temperature 33.5°; sample of air from the bag . . . . d 



5:05. Absolutely without sensation except in the eye. 



5:20. Respiration 68; pulse 80; temperature 32.8°; air from the 

 bag . . . . e 



5:35. Temperature 32.2°. 



5:45. Air .... f 



5:48. Respiration 52, somewhat irregular; pulse 58, very weak; 

 temperature 32°; 30 cc. of blood . . . . G 



The cornea becomes insensible; the conjunctiva still retains some 

 sensitivity. 



6 o'clock. Respiration 44; pulse 44; temperature 31.2°. 



6:10. 25 cc. of blood . . . . H 



The bag is removed, after a sample of air for analysis has been 

 taken . . . . g 



After a few respirations in the open air, the animal displays 

 rigor, which lasts only a short time. When placed on the floor, it 

 twists slowly, without apparent consciousness. 



I remove the tracheal tube. 



About 6:30, consciousness returns very clearly. At 7 o'clock, 

 when stimulated, stands up, and tries to walk. 



The next day, quite recovered; survives. 2
