398 APPENDIX. 



What Encouragement to the Attempt, that there 

 are fuch Multitude of Objeds for the Tryal ; and 

 that the difcovering but one Remedy among 

 them all, for a Difeafe we knew not how fo well 

 to cure before, is a Source of more true Ho- 

 nour, than can be derived from all the ufelefs 

 Knowledge in the World. 



Ifanyfuppofe the Tryal dangerous, they mif- 

 lead themfelves ; and to encourage fo laudable dh 

 Undertaking, I ihall obferve how little is the 

 Hazard, and how confiderable the Advantages, 

 ^rom what we know already. 



If a Man were to be turned loofe upon an 



Ifland where no Perfbn had fet Foot before, he 



might dread to Talre^F any Plant he faw, be- 

 caufe he might not know, but every one he law 

 ■was fatal : And fuppofing him to have got over 

 this Fear, the Ignorance of the Virtues of all 

 ■would keep him backward : But this is not at all 

 the Cafe with him, who Ihall at this Time fet a- 

 bout inquiring into the Virtues of Plants in Eng- 

 2and. The poifonous Plants, native of our Soil, 

 are hardly a dozen, and thefe are chara^ered eveii 

 to the Eye, by fomething lingular or difmal in 

 the Alped. They are well known ; and he has 

 nothing to do, but to avoid them. For the reft, 

 he has fo many, whofe Ufes and Qualities are 

 already perfe(51:ly known, that he has a great Foun- 

 dation to go upon in the Search, becaufe he can 

 compare thofe he doe? not know with them. 

 Their Taftes will go a great Way toward inform- 

 ing him i but this is not all, their very outward 

 Figures will direct him : For in general thofe Plants 

 which agree in the external Afpeft, agree likewife 

 jn their Virtues.
