But the reafon of the abatement of the 

 bleeding in this cafe may well be account- 

 ed for, from the manifefl proof we have 

 in thefe Experiments, that the fap is flrong- 

 ly attracted upwards by the vigorous ope- 

 ration of the perfpiring leaves, and attract- 

 ing Capillaries : But when the bark is cut 

 off for fome breadth below the bleed in o- 

 place, then the fap which is between the 

 bark and the wood below that disbarked 

 place, is deprived of the flrong attra&ing 

 power of the leaves, &c. and confequently 

 the bleeding wound cannot be fupplied fo 

 fail with fap, as it was before the bark was 

 taken off. 



Hence alfo we have a hint for a probable 

 conjecture, why in the alternately disbarked 

 flicks, 1 1 a a, Fig. 28 29. the bark fwclled 

 more at the upper part of the disbarked 

 places than at the lower; viz. becaufe thofe 

 lower parts were thereby deprived of the 

 plenty of nourimment which was brought 

 to the upper parts of thofe disbarked places 

 by the flrong attra&ion of the leaves on the 

 Buds 7, &c. of which we have a further 

 confirmation in the ringlet of bark, N°. 13, 

 Fig. 29. which ringlet did not fwell or grow 

 at either end, being not only deprived of
