gone, though a fmall degree of the confuiion in it 
{fill remained. Upon going to {fool that morning, I 
was extremely colfive, though I had not been fo 
before, nor continued to be fo after. All that day 
I felt a great forenefs, and rigidity over my whole 
body, as if I had caught cold, or undergone fome 
fevere exercife ; the next day I was fomething better, 
and the day following quite recovered. 
As the foregoing experiments had not fully fatis- 
fied me, whether camphire adted as a heater or 
cooler on the body, I refolved to try if it would give 
any additional heat or cold to fluids, in which it was 
diflolved ; but, after repeated trials, I found that it 
never altered the natural heat of fpirits, or oils, in 
whatever degree they were impregnated with it. 
The firft dofe I took was a moderate one, and ap- 
peared to have adted as a cooler; but the next, if 
there is any trufting to the fenfations occafloned by 
it, or to the increafed celerity of the blood, certainly 
bsve heated to a very great degree.
