in the manner of Caring it. Oar Experience has contra- 
dicted our Belief, and the Remedy that has proved 
Effectual and Sufficient in one Cafe, has proved inef- 
fectual and Ufelefs on other Occafions ; on which 
Account Remedies are very liable to be mifapplied. 
To prevent this Misfortune in a great Mealiire for 
the Future, I fhall confider the Medicines commonly 
made ufe of by Phyficians for the Cure of a Loofe- 
nefs; and next, how they may mod properly be 
adapted to that End: For thus we mud perceive the 
particular Cafes wherein they are like to beufeful, and 
when they are not like to be of any ufe at all. 
AJlringents , or binding Medicines, were the firft 
employed for the Cure of a Loofenefs, as well as of 
every other Evacuation ; But Hippocrates obferving 
that a Loofenefs was often the eafieft cured when it 
was attended with Vomiting, Vomiting Medi- 
cines were introduced on that Account. On a like 
Confideration, Purging Medicines were admitted by 
Celfus , becaufe he found the Purging the Cure of 
itfelf; or that the Loofenefs went off by going 
to Stool for a few Days : But he advifes Phyfi- 
cians to take care that the Loofenefs does not run 
longer than feven Days, and that it is not attended 
with a Fever ; for in that cafe the Loofenefs is not 
Critical and Salutary , but Symptomatical, and ha- 
ftens on the Ruin of the. Sick. All thefe Obferva- 
tions have not been found univerfally true in many 
other Countries ; for Ccelius Aurelianus , a mod ac- 
curate Obferver of Difeafes, Rhaza and Avicenna 
blame this freeUfe of Purging and Vomiting, and may 
be juftified by what will be lhewn in the Progrefs of 
this Difeourfe.
