and not break the skin 5 there followed no grea ter fwel* 
Kng, that I could difcernj on the one fide of the filk than on 
the other J although in often repeating the Experiment^ 
fome filks were left hours and dayes unloofed^ and yet the 
diniple which the thread had made in the yielding branch- 
esj had a little raifed theimmediate fides^ but bothalike! 
the Plant in like manner would bleed very freely both a** 
bove and under the Tye^ This was ahb^ I thought, very 
remarkable, amongft other things, in this Experiment^that 
in drawing the Rafour round about the branch juft above 
or below the Tye^ the Milky Juyce would fuddenly fpring 
out of infinite fmall holesj befides the made orifice 5 for 
more than half an inch above and below the Tye : which 
leems to argue , that though there was no Juyce intercep- 
ted in appearance from any turgefeence^ (as in the procels 
upon the members of a Sanguineous Animal J yet the Veins- 
were fo over- thronged and full, that a large orifice was not 
lufEcient todifcharge the fudden impetus and prefTure of

To the end that I might fatisfie my felf about fome of the
