IK My friend Mi', park, an ingenious furgeon of this 
place, went into the flove heated to 202°. After ten mi- 
nutes, I found the pulfe quickened to 120°. And to de- 
termine the increafe of the animal heat, another ther- 
mometer was handed to him, in which the quickfilver 
already ftood at 98°; but it rofe only to 99^, whether 
the bulb of the thermometer was inclofed in the palms 
of the hands, or received into the mouth The natu- 
ral, ftate of this gentleman’s pulfe is about 65. 
III. Another gentleman went through the fame ex- 
periment in the fame circumltances, and with the fame 
effedts,. 
IV. One of the porters to the Hofpital, a healthy 
young man, and the pulfe 75, was inclofed in the hove 
when the quickfilver ftood at 210°; and he remained 
there, with little iuconvenience, for twenty minutes.. 
The pulfe, now 164, and the animal heat, determined 
by another thermometer as in the former experiments, 
was ioi{. 
V. A yoting gentleman of a delicate and irritable ha- 
bit, whofe natural pulfe is about 80, remained in the 
ftove ten minutes when heated to 224°. The pulfe rofe 
to 145, and the animal heat to 102°. This gentleman,, 
who had been frequently in the ftove during the courfe 
of the day, found himfelf feeble, and difpofed to break 
out into fweats for 24 hours after the experiment. 
(e) The fcaleof the thermometer, which was fufpended by the ftring about , 
the middle of the room, was of metal; this was the only one 1 could then prc-- 
cure, on which the degrees rair fo. high as to give any fcope to. the experiment. „ 
The fcale of the other thermometer, v/hich was employed for afcertaining the 
\ariatiofts in the aAimal heat, Wiis of ivory,
