Thefe few inftances iliew the va- 

 rious ways in which this beneficial

 more of fuch remarkable peculiari- 

 ties among leaves of different plants ; 

 but thofe above mentioned will be 

 fumcient to fhew, that each plant 

 follows in this regard its own na- 

 ture ; and that, therefore? thefe dif- 

 ferent appearances feem to depend 

 upon fome vital motion ffoino- on in 

 the fubftance of the leaves.
