the Negroes may have the Knowledge of different 
Sorts ot Poifon, I deny not,- but it would appear, 
from the Univerfality of theEffeds of this Medicine, 
as the Do&or affirms many have been wonderfully 
cured and preferved by it, and does not mention a 
dingle Instance of its Mifcarriage, as though the Ne- 
groes in the Weft-Indies ufed but 00* Kind of Poifon, 
or, if different, yet fuch as comes within the Power 
of this Remedy. Befides, as we cannot be allured, 
but by the Confequence, whether the Poifon be of 
that Sort, as to be within the Reach of this Remedy, 
or not, I think there is all the Reafon in the World 
it fhould be adminiftefd under any Sufpicion of the 
Indian Poifon : Efpecially, as the Dodor allures us 
of its great Innocence; and I believe every one will 
readily agree with me, that it is no fmall Recom- 
mendation of a Medicine, That let what will be- 
come of its good Effects , it can do no Harm. 
Hiofcorides hath rightly obferv'd in his Alexi- 
pharmics, that very different Foifons produce the 
fame Effehls upon Human Bodies ; and that there- 
fore they are , for the mo ft part , curable by the fame 
Remedies. For though the Kinds of Foifons are 
various , yet the Eft ells which arife from them 
are common , and but few t* And that Ornament 
of his Profeflion, the learned and beneficent Dr. 
Mead , who hath given us a more rational Account 
t Fere enim plurimorum Venenorum faculrates in confimiles 
effe&us Corpus tandem deducunt : quam ob caufam plerifque com- 
munia conducunt Auxilia. Varia equidem funt Venenorum genera: 
communes tamen, nec ita multi, qui ex iis oriuntur, affedus.
