globulin the least so. Of the six experiments with the former, in four there was 

 a primary increase in the pulse-rate followed by diminution, and in one case by a 

 subsequent increase; in the other two there was a diminution from the first, the 

 pulse regaining its normal frequency, or, as in one instance, rising above it. 



In both the experiments with copper-venom-globulin there was a primary increase 

 followed by a diminution in one case, and in the other by a return of the rate to 

 about the normal. 



In the three experiments with dialysis-venom-globulin, a primary increase occur- 

 red. In two this was followed by a drop below normal, while in the other the 

 rate remained above the normal.
