the South- Eafty and the weather broke up a pace* The Syca- 
mores bled not all this whilejbut the 7th about Noon all Trees 
of that kind bled very freely, both at the Twigs and Body» 
and I ftruck above a dozen*. 
At this fame Critical feafon I was willing to repeat the Ex- 
periment upon other Trees ^ and to this end I forthwith ftruck 
the Hawthorn, Hazely IVild-Rofe ^ Goofe herry-bujh ^ Apple-tree^ 
Cherry-tree^ Blather nut y Apricock^y Cherry-Lawrel^ Vine^ Walnut*^ 
yet none bled but the laft-named, and that faintly in compa- 
. rifon oixSx^ Sycamore. This is confcnant to our former Experi- 
ments : And if it did happen ( as I faid in my former Letter, ) 
that theie Sycamores bled not all this Winter afore at the 
wouruls made the firft ofNovember^l do now thinkjthat if new 
wounds had been ftill made at every break ofFroft, fome 
fignes>atleaft ofour r<?r4-/;ire bleeding, might havebeen dif» 
cover'd before now* But / affirm no more, than / hav^ feen

In all the Monuments of the Antients, collefted by the great 
induftry ofPlwji^ I find but few inftances of this nature* A- 
rnoHgft thofe few, there is one that is regiftred with two or 
three remarkable circumftances to our purpofe. He tells us, 
thatthePhyfitiansof old, when they had a mind to draw the 
Juyceof theMalberry-tree, were wont to ftrike it skin-deep 
only, and that about two hours after Sun-riie. This Experi- 
rnent is twice mentioned by him, and in both places as a 
ftrange phosnomenon. We might make our Comment upon 
the places, but for this time are content only to tranfcribe the
