with great Praife, of which others have made lits 
tle Account : Thefe are the Means by which the 
firft Gueffes have been made about their Virtues 3 
and Experiments have always confirmed them. 
It has not always happened, that the Virtues of a 
Plant thus tried, have been in a Degree worth 
fetting in a Light of Confequence: ‘They have 
been fometimes flight, and the Plant has been dif. 
regarded ; but they have fcarce ever miffed to be 
found. of the fame Nature. pats 
_ Thefe Experiments, I have always thought Ho- 
nefty required of me to make upon myfelf, and 
I never found Harm from the Tryals. I had no 
Right to bring into the leaft poffible Danger the 
Health of others ; as to my own there was no Pro- 
bability of Harm; but if it had happened, the 
Intent would have fanétified the Accident, and’ 
I fhould have been contented. 
There is this great Ufe in examining other Plants 
_ which have the fame Sort of Flowers and Fruits ° 
_ with thofe, which we know to have Virtues, that 
_ Wwe may in this Way difcover Plants at Home, to’ 
upply the Place of thofe we have from other 
Countries. It is certain the Sun in warmer Cli- 
mates does ripen the Juices of Vegetables farther 
than in ours, but yet we find the Plants of the 
fame Kind from whatever Part of the World they 
come, to poffefs nearly the fame Kind of Virtues; 
generally indeed they are the fame, only differing — 
in Degree. Thus all the Mallows of Spain and 
italy, to bring the Tryal to the before named 
nftance, poffefs the fame Virtues with the Maxh- 
mallow, Mallow and Holyoak of England; 
and the Cafe is the fame with thofe which are 
truly Mallows of the Zaft and Weft-Indies; though 
this do not hold good with refpect to fome of
