5:07. Drew 25 cc. of very dark blood . . . . E 



5:08. The eye, till then sensitive, becomes insensible; the pupil 

 dilates. 



5: 10. Respirations 6; pulse 30. 



5: 15. Urine; the respirations become slower and slower and weaker 

 and weaker; the heart also is failing. 



5:20. Died without convulsions. Took air from the bag . . . . e 



Took blood from the left heart . . . . F 



The urine contains 18 cc. of C0 2 per 100 cc. of liquid.

 is, for 1 hour 20 minutes.
