at the rate of 24 or 27 Pulfations in a Minute, 
for three or four Minutes. After this I laid the 
Paper upon the Palm of my Hand, the Warmth 
of which increafed the Number of Pulfes to 37 
the firft Minute, and to 48 the fecond. Laft of 
all I put it into warm Water, a Degree or two 
warmer than the Blood, where it beat 87 Pulfes the 
firft Minute, and afterwards declined in its Motion 
more and more till it quite ceafed. 
CLI. 
May we not from hence obferve what vaft Influ- 
ence Heat had upon the nervous <^yEther to make 
it fly fo quick into the Heart as to increafe the Pulfe 
to almoft four times their ufual Number ? How far 
the Heat in fome fort of Fevers may quicken the 
Pulfe, is not to our prefent Purpofe to enquire, 
CLII. 
It is amazing to think that fuch very fmall For- 
tions of the Nerves, as were cut out with the Heart 
in this Experiment, (hould contain Matter fufficient 
for fo many Contraftions j and that it did not all 
of it inftantly fly out from the wounded Ends, even 
before it was put into warm Water. 
CLIII. 
How far thefe Experiments may ferve to illuflrate 
and confirm the Truth of our Theory of mufcular 
Motion, is very humbly fubmitted to the candid 
I Judgment
