qiuntlty. When the bilious matter has once entered the blood 

 (vvl)!ch it will foon do, if fwcats are iiicaiuioofly ufed at firft), 

 vomits and acid purges become le(s ufetui; and the morbid matter 

 mufl: be thrown out upon the Ikin by wild-fiige tea, weak punch, 

 or other liquors which promote a flight diaphorefis. In this dif- 

 order it often happens, that a weak purgative, or emetic, will 

 produce uncommon evacuations. This (hould not alarm ; and tlic 

 patient's ftrength fhould be well ilipported witli ?%4adeiia whey. 

 This fever often fubfidts into a remittent, and then into an inter- 

 mittent, whofe beft remedy is the bark, wiiich not only produces 

 a wholefomc bile, but invigorates the whole habit. Fluxes and 

 dyfenteries proceed often from the fame caufe, a corrupted bile, 

 and fometimes from a fupprelt perfpiration, or too free indulgence 

 ill crude, watery vegetables. Of all the fubftances known, the 

 bark, and ripe orange or lemon juice, deferve, for their excellence, 

 the name of fpecific againft putrefaction. I knew an European 

 gentleman in Jamaica, who regularly drank every day a Imall 

 tumbler full of fweet or four orange-juice, ufing them in- 

 differently, immediately after dinner, and enjoyed conil ant health. 

 I remember another who cured himfelfof a bilious putrid fever 

 with no other remedy than the juice of ripe Seville and other 

 oranges. And fo many inftances have been noticed of their anti- 

 leptic quality in the(e cafes, that the utmofl confidence may be 

 repofed in their falutiferous efFeCls. 



Much more might be added on the fubje£t of thefe diitempers, 

 their caufes, (ymptoms, and method of cure ; but, as I mean not 

 to enter into an elaborate and medical invefligation of them, I refer 

 to the writings of Pringle, Huxham, Lind, Bifiet, Hilary, J\ouppe, 

 and De Monchy, who have treated of them with the greated 

 ability. 



Mofl: Europeans, on firft coming within the Tropics, are afFeded 

 with an eruption upon their Ikins of fmall red pimples, which goes 

 by the name of the pv'iclJy beat. This is looked upon to be falu- 

 tary, unlcfs it is repelled ; and it is remarkable, that it returns pe- 

 riodically every year, about April or May, on pcrfons who have 

 redded a long time in the Weft-Indies [?;]. It is, probably, caufed
