372 APPENDIX 



It has not always happened that the virtues of a 

 plant thus tried, have been in a degree worth 

 setting in a light of consequence ; they have been 

 sometimes slight, and the plant has been disregard- 

 ed ; but they have scarce ever missed to be found 

 of the same nature. 



These experiments, I have always thought ho- 

 nesty required me to make upon myself, and I 

 never found harm from the trials. 1 had no right 

 to bring into the least possible danger, the health 

 of others ; as to my own there was no probability 

 of harm : but if it had happened, (lie intent would 

 have sanctified the accident, and I should have 

 been contented. 



There is this great use in examining other plants 

 -which have the same sort of (lowers and fruits 

 with those which we know to have virtues, that 

 we may in this way discover plants at home, to 

 supply the place of those we have from other 

 countries. It is certain the sun in warmer climates 

 does ripen the juices of vegetables farther than 

 in ours, but yet we find the plants of the same 

 kind from whatever part of the world they come, 

 to possess nearly t!ie same kind of virtues ; gene- 

 rally indeed they are the same, only differing in 

 degree. Thus all the mallows of Spain and Italy, 

 to bring the trial to the before-named instance, 

 possess the same virtues with the marsh-mallow, 

 mallow, and holly oak of England ; and the case 

 is the same with those which are truly mallows 

 of the East and West Indies ; though this does 

 not hold good with respect to some of the 

 plants of those countries which have been brought 

 hither under that name. 



Thus also, that root which was at one time 

 about to be brought very much into use, under 

 the name of the Senegal rattle-snake root, hut
