Thirdly it is the Jadgmennaf the moft learned and 
experienced Pra&itioners, that Vemits in their Nature 
and Power differ little from ordinary Poifon. How is it 
then poffible that one Poifon (hould qualify the other > 
Laftly, if they be confidered as Auxiliary Remedies, then 
let them be adtniniftred with the greateff Caution that 
can be, efpecally at a Time when they choke and kill 
fo many Symptomatically. If an Argument a Pojleriori 
may be allowed conclufive, then, as we faid before of 
Bleeding, we may alfo of x Vomits, that they prognofti- 
cate an unhappy Event to the Difeafe, and that they 
have not the leaft Ufe imaginable in preferving from: 
Contagion. Ic happens fometimes that a Man over-

This is undeniable 5 but it is certain that fuch Crudities 
in the Body can neither increafe nor promote the con- 
tagious Miafma, feeing, as I have obferved above, it im- 
mediately feizes the Nerves, and fo occafions Convul- 
fions and Spafms, which frequently fcour and cleanfe the 
firft Paflages more than is neceffary infomuch, that: 
when nothing more can be expelled out of the Stomach, 
the Gall itfclf is brought up fometimes with fuch Vio- 
lence, that the very Vifcera are ready to be torn to 
Pieces. 
From whence it appears, that no Remedy can be 
more dangerous than Vomits. What is it then that can 
prevail upon a Phyfician-t&-recommend them, and that 
without any Caution, efpecially to fuch as do not know 
how to take Care of themfelves? And every ordinary 
£erfon is. fo eafily perfwaded to them, that if but the
