54 | TRAVELS TO DISCOVER: 
Polka as 
was-comapleted. Immediately when a. nauféa:or averfion 
to eat, frequent fits of yawning, ftraitnefs.about the eyes, and: 
an unufual, but not painful fenfation along the {pine, comes. 
on, no time is then to be loft; {mall dofes of the bark muft 
be frequently repeated, and. perfect abitinence obferved, un- 
lefs from copious draughts of cold water, . 
I never dared to venture, or feldom, upon the deluge of 
water, but am convinced it is frequently of great ufe. The 
fecond or: third dofe of the bark, if any quantity is fwal- 
lowed, neverfails to purge; and, if this evacuation is copious, 
the patient rarely dies, but, on the contrary, his recovery 
is generally rapid: Moderate purging, then, is for the moft 
part to be adopted ; and rice is a much better food than fruit.. 
I xnow that all this is. heterodox in Europe, and contrary-: 
‘to the practice, becaude it is contrary to fyftem. For my. 
own part, I am content to write faithfully what I carefully - 
obferved, leaving every body afterwards to.follow their+ 
own way at their peril. 
Bark, | have been .told by Spaniards who have been in: 
South America, purges always when taken in their fevers... 
A different climate, different regimen, and different habit of 
body or exercife, may furely fo far alter the operation of a. 
drug as to make. it have a.different effect:in Affica from. 
what it has in Europe. Be that as it may, ftill I fay. bark is: 
a purgative when itis fuccefsful in this fever ; but bleeding,., 
at no flage of this diftemper, is of any fervice ; and, indeed, if - 
attempred the fecond day, the lancet is feldom followed by 
blood. Ipecacuanha both fatigues the patient and: height-- 
ens the fever, and to conducts the patient more fpeedily to his;
