trouble to me be;for€ I could place it In fuch a pofiuonj as 
ill J Limner might be able to draw it exaftly. 
Fig, H I K L M N reprefents a part of the fame String 
cut acrofs, which Fig. x. F G gives you entire, and in its 
whole length. 
Thcfaid Particle of the String at H I M N has abundance 
of exceeding fmall Velfels, but very hard to be feen, a- 
bout I K L M they grow larger, and confcquently more 
vifibl i^ and thus you may fee a great many, tho not all 
of theVelTels. 
After I had made this obfervation, I was thinking whe- 
ther thefe great Veffels were not the origin or fource of 
the contexture of that Membrane which covers the Seed 5 
and on the other fide, whether the former defcrib'd by 
H I M N were not the feeders of the Seed and Plant. 
I had ahbplac'd a piece of another ftring of the Kernel 
of an Orange before another Microfcope, of which I have 
given you a rough draught, only to (how how the utmoft 
Membrane incompafles the String in order, aslfuppofe, 
for its ftrength and defence. 
Fig. 4, O P reprefents the faid String cut acrofs, R S 
T V that part of the hard Membrane that furrounds it, 
T VCLWare fiuntly fhewnthar infinite number of Fibres, 
particularly at ClW, that Nature ufes in the contexture of 
fuch a finall String. 
The laft Phenomenon .fuggefted to my thughts, that 
thofe long Fibres reprefented by CLW were defign'd to add 
a ftifFnefs and folidity to the outward Membrane, for rhe 
better defence of the internal Veflels. 
I have often obferv'd that theoutmoft Membrane RSTV 
did comprefs the String foclofely, that there remained little 
fpace between them. 
In the faid Fig. 4. X Y Z is reprefented that Membrane, 
which furrounds the Kernel cr Seed and the Plant ^ the 
faid Membranes are very thin, and particularly the in- 
moft of them.
