the fcorching of the floor, and with a piece of paper be- 
fore its head and breaft to intercept the dire6l heat of the 
cockle. In about ten minutes it began to pant and hold 
out its tongue, which fymptoms continued till the end of 
the experiment, without ever becoming more violent 
than they are ufually obferved in dogs after exercife in 
hot weather ; and the animal was fo little affedled during 
the whole time, as to fliewfigns of pleafure whenever we 
approached the bafket. After the experiment had con- 
tinued half an hour, when the thermometer had rifen to 
236°, v/e opened the bafket, and found the bottom of it 
very wet with faliva^hut could perceive no particular/it'/or. 
We then applied a thermometer between the thigh and. 
flank of the animal; in about a minute the quicklilver 
funk down to 110°: but the real heat of the body was 
certainly lefs than this, for we could neither keep the. 
ball of the thermometer a fufflcient time in proper con- 
tad:, nor prevent the hair, which felt fenlibly hotter than 
the bare fkin, from touching every part of the inftru- 
ment. I have flnce found, that the thermometer held in, 
the fame place, when the animal is perfedly cool and at , 
reft, v/ill not rife above 101°. At the end of thirty-two 
minutes the bitch was permitted to go out of the room; 
upon coming into the cold air flie appeared perfectly brilk 
and lively, not in the leafl: injured by the heat, and has . 
now continued very well above a month. Our experi- 
ment, therefore, differs, in every eflential circumftance 
of the event, from that related by Dr. boerhaave. With 
refped to this laft it is remarkable, if the fads be pro-
