time in the incermiflion, and although fome times I have obferv’d on 
giving it about four hours before the Fit, that the Fever came more 
violently on the Patient than before, yet I never could find the 
giving of ic then dangerous. This I was firft tanght by giving ic 
accidentally to one whofe Fit anticipated its time, or came fooner 
than he expected, coming from a Tertian to a double Tertian or 
Quotidian. Several Chymifts and Apothecaries in Augland and France 
pretend to an Extract or TinCture of this Bark of equal vertue with 
it, which becaufe of the unpleafant taft of the Powder, in fub- 
fiance were very valuable, but on giving both Tincture and Extract 
in the Dofes prefcribed, they are found far lefs effectual than the 
bark in fubftance. Although where the Powder in fubftance cannot 
be taken, thefe are the next beft Remedies, yet they are not tobe 
depended upon. Tis moft certain that the Scomach and Guts, with 
their juices, furpafs all Artificial Veflels and Men/irunms in Extracting 
what is beneficial from this Simple, and that no Art is able to make 
fo effeétual a Medicine out of it, asthe Bark its felf, as ic happens 
in many other cafes, ‘This Powder, when I went to Jamaica, was 
in very great difrepute here, infomuch thac it was charg’d withthe 
death of feveral People, whereas the ignorant way of giving ic was the 
caufe of its difgrace. The Inhabitants ufed to Purge after it to 
take away the Relicks of the Powder, which never mifles bringing a 
Relapfe. They likewile faild in not giving fo great a quantity as was 
{ufficient, or as it ought to be given. They ufed only juft before the 
coming on of the Fit, to give fo much as might prevent it, with- 
out any farther regard to the Fever. Avoiding thefe Rocks, wich 
the bleffing of God I never mift the cure of Quotidian, Tertian, or 
Quartan, in whatever Age or Sex, and-although I have given it to mae 
ny hundreds, yet I never knew any bad confequence on its ule, which 
with juftice I could afcribe to it, but always a periet recovery. 
Indeed it will aot cure all Difeafes, neither will it touch upon a con. 
tinual Fever, but in this laft, I chink, it any prejudice arile to the 
Patient by it, “tis only chae it muft be caken in large quanuties, and 
hinder perhaps che taking of more proper Remedies. It very often 
works by infenfible Perfpiration, and fometimes by Sweat, the 
Patient having a breathing, and fometimes more copious Sweat 
every night after caking it. Intermicting Fevers here, are call'd Fe- 
vers and Agues. A Phyfician who had practis'd many years in Bar- 
bados, told me there was no fuch Diftemper there, and chat from che 
Leeward (lands (where it was common) they came thither, and were 
curd by that Air. The caufe of the great frequency of the Agues 
in Jamaica, at fome times of the years, are the Rains which fall fo 
violently, and continue fo long as that the low Plains are for fome 
time covered wich water. Hither Aquatic Birds, and thofe ieee
