 pofed to be cut off at c , and to be out of 

 the ground : For by many Experiments in 

 the firfl: and fecond chapters , it is evident, 

 that the branch b attra&s fap at x with 

 great force : And by this prefent Experi- 

 ment, 'tis as evident, that fap will be drawn 

 as freely downwards from the tree to x, as 

 from c to x , in cafe the end c of the root 

 were in the ground 5 whence 'tis no won- 

 der, that the branch b thrives well, tho 3 

 there be no circulation of the fap. 



This Experiment 41, and Experiment 2.6, 

 do alfo fhew the reafon why, where thefe 

 trees (Fig. 24) are inarched, and thereby 

 incorporated at x and z , the middle tree 

 will then grow, tho' it be cut off from its 

 roots ; or the root be dug out of the ground, 

 and fufpended in the air 5 viz. becaufe the 

 middle tree b attradrs nourishment ftrongly
