and more equally must increased heat of the blood become percep- 

 tible in the various organs. As a measure of the action of the heart, 

 the frequency of the pulse may in sound individuals be employed, 

 and this, other things being the same, gives a relative expression 

 for the quantity of blood sent peripherally in a given time.

On the accompanying plan curves for the rectal temperature
