diftance it was red, and in another place blackilh. 
Upon cutting it tranfverfly, I faw the Orihces of the 
afcending Veflels, which ran along the length of the 
Wood and which appear’d of fuch a fize in the 
Microfcope that one would have judged a Pea might 
pals thro them. Where the Wood look’d reddilh I 
found thefe great VeiTels fill’d with a Subfiance of’ a 
fine red colour, fo that I imagin’d, that thefe great 
VelleiS carried a red Sap into the Horizontal VeiTels 
which appear’d fo very numerous, and fo thick to- 
gether, that they caus’d the Wood to appear of the 
fame colour with the red Subfiance, which was con- 
tain d in thofe VeiTels likewife. 
I afterwards cut ofF feme very thin flices tranf- 
verfly from this W ood, and putting them into a China 
Cup, i pour d fome hot Water upon them, and fufferd 
the ™ f ° ! le in ir for fome time ; then viewing them 
with a Microfcope, 1 obferv’d that the red Subftance 
was extracted by the Water, and no red colour was; 
now to be found in any of the VelTelsa 
What feem’d the flrangeft to me in this Wood 
was that cutting thro’ the W’ood lengthways, as I 
frequently did, I obferv d it to be of a fine red co- 
lour for one Hair’s breadth, and a Hair’s breadth far 
ther it appear’d white; and the afcending VeiTels. 
ieem d to be fmaller, where the Wood was red than 
where it was white : which narrownefs of the red 
Veflels I judged to proceed from the Sap contain’d 
in them. *
