Dr. T. A Branch, wfyofe Birkof the breadth of about 2 or K 
3 Inches is taken off roiiad towards the bottom, in fome Trees, 
and particularly the Lime-tree,w\l\ live,and bear leaves for many 
years, and grow, as other branches,by means of th<? fap amend- 
ing through all the pores of the inner Coats, as was faid above 
to the 3d ^ And it ought to be well obferved, in what other 
Trees this will hold,and especially, whether it will not hold in all 
Trees, whofe fap runs not out very plentifully for, in fuch 
Trees, wherein there is a plentiful Iffueof the Sip between the

To the 6th. Dr, B. Concerning the life of the Pith in Vege- 
tables, as whether the Juyce afcends or defcends by it t It may 
be confider'd, That my Anfwers above do import that the 
Juyce, which defcends by Tapping, and which maketh the pulp 
or coat of any fruit, afcends by the Bark or Rind of the Plant, 
not by the Pith. I now add (which I can affirm by many Ex- 
periments ) that the Pith, and the Timber have fome correfpor- 
dence with the Seed of the Plant, toconveigh an enre ourfe of 
the fame Spirits and nature from the Root to the Seed. 
The Experiments themfehes, whereby theWorthi Doffor maketh 
this ottt^ we mufl refer to another opportunity 5 as alfo his con fider able 
Bifcourfe already in our hands , giving Inflavces to- (I)Cw,That there 
is a peculiar Correfpondence, not onely between the Seed and the 
Pith, Heart or Timber of Plants $ bat alfo between the B irk or Sap 
in the Barky and the Pulp of the Fruity or fome encempafsing Coat 
or Husk^ or Cod, which contains the Seed.
