An Advertence to the foregoing. 



THE remarks of my friend refpecting the pro- 

 bable alteration in the diftinguiming quality and 

 flavour of fruits, by an indifcriminate planting of 

 various fpecies of apple-trees together, are unquef- 

 tionably well founded \ but whether the entire de- 

 pravity can be conquered, and a perfect. regenera- 

 tion of the original fpecihxk quality of the fruit "be 

 recovered, is a matter of queflion. For we may 

 confider the circulation of the lap in trees as fome- 

 what analogous to that of the fluids in animated* 

 bodies; and that the latter imbibes falubrity and 

 contagion from the approximation of different fub- 

 jecb; whereby a conibtutional change is fometimes 

 effected.
