The Fibrous Branches reprefented by V. V. V. arc 
thofe that were cut off with a Knife. 
Forafmuch as it was not eafie to difcover with the 
Eye, how the faid Fibrous Parts, with their Branches 
and Roots, did proceed out of the Membrane, I caufed 
the Painttr to view a fmall Particle of the fame thro the 
Microfcope, juft as ’twas faften’d in the Membrane, as 
may be feen in Fig. 2. which Membrane is there repre- 
fented by A. B. as are alfo three Branches by C. D. . D. E. 
and E. F. All which are united in the Fibrous Branch 
C. H. I* and then we faw how each of the three faid 
Branches, with thofe Parts thereof that I call Roots, were 
proceeding out of the Membrane, as is here fhown 
in Fig. z. between F. K. . E L. . D.M.. and C. N- info- 
much that the Painter faid tome, that he never in his 
life faw more Roots with his naked Eye growing out of a 
Tree that was thrown down with the Wind, than he 
faw in this Figure. 
T^at we may have a more exaft Idea of the ftru&ure 
of the Spleen, I handled feme parts thereof much more 
f ently than I had dope the greater, that I might lay the 
ibrous Parts naked 3 after which I placed a fmall Parti- 
cle thereof before a Microfcope, and caufed the Painter 
to defcribe the fame as well as he could. 
Fig. 3. A.B. C. D. E. F. G. H.I. reprefents a little piece 
of the Spleen, which to the naked Eye was no larger 
than a courfe Grain of Sand. In which Figure between 
A. B. and A. J. you don’t only fee the fmall Branches 
that {hoot out of the Fibrous Part, which are alfo compos’d 
of much fmaller Parts themfelves, but one difcovered 
alfo in the faid fmall Particle, that it felf in the length of 
it did alfo confift of long Particles like Fibres. Then 
who knows, but each of thofe fine Particles are Tubes or 
Veffels, to convey that very thin Juice or Liquor which 
they receive out of the Membrane.
