ACTION OF ALCOHOL UPON CIRCULATION— WOOD AND HOYT. 



45 



and oedema due to the local action of the alcohol upon the pulmonic mucous membranes. At 



such times the pulse was slow and full, and it was clear that the circulatory changes were the 

 outcome of asphyxiation. In most of the experiments the animal died suddenly l>v respiratory 

 failure, there either being no unconsciousness until the act of death had been entered upon or 

 was about to begin. It has not .seemed to us necessary to report the experiments of this series 

 in detail, but we have tabulated one typical experiment, in which there was no rise of arterial 

 pressure. 



Experiment 1. — Alcohol given by Inhalation. No morphia. Small amount of ether. Reflexes 



normal befort beginning experiment. 



The following experiments were directed simply to studying the effects of the intravenous 

 injection of alcohol upon the circulation in the normal dog. In all of the experiments ether was 

 used during the preparation of the artery and vein, care being taken to allow the effects of the 

 ether to go off before the first record of blood pressure. In a few instances a small amount of 

 morphia was also given to the animal operated upon. 



Experiment 2. — Weight, 7\ kilos. 



Alcohol, 10 per cent, until strength increased us given in
