notwithftanding the root c x is here fup- 
pofcd to be cut off at Cy and to be out of 
the ground : For by many Experiments in 
the firft and fecond chapters , it is evident, 
that the branch b attrafts 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 y in cafe the end c of the root 
were in the ground $ whence 'tis no won- 
der, that the branch b thrives well, tho’ 
there be no circulation of the fap. 
This Experiment 41, and Experiment 2(5, 
do alfo fhew the reafon why, where thefc 
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 5 or the root be dug out of the ground, 
and fufpended in the air 5 becaule the 
middle tree b attraiSs nourifhment ftrongly 
at X and Zy from the adjoyning trees a Cy in 
the fame manner as we fee the inverted
