Experiment 11. — Cord cut in cervical region. Weight, 10 pound*. 



Experiment 12. 



- Weight of dog, 10.5 kilos. Cord cut in the lower cervical region, 

 hemorrhage during flu operation. Alcohol used, 50 j» r cent.

An inspection of those experiments will show that in Experiment 7, in which the dog- was 

 young and vigorous, the arterial pressure was raised over Km per cent in spite of the consentaneous 

 marked decrease in the rate of the pulse; that in Experiment 8 the pressure was raised about 25 

 per cent at the maximum in spite of the fact there had been a great deal of hemorrhage from the 

 operation; that in Experiment '.» the pressure was elevated as much as 50 per cent at the maxi- 

 mum, the pulse being reduced in frequency; that in Experiment It) although there was much 

 hemorrhage the elevation of pressure at the maximum was about 25 per cent; that in Experi- 

 ment 11 the maximum rise of pressure was about 4<i per cent; that in Experiment 12 the maxi- 

 mum rise of pressure under the use of alcohol was about 50 per cent. 



In none of these cases was the arterial pressure kept for a great length of time at the highest 

 point, but there was always a prolonged maintenance of the pressure above the normal.
