entations of the Structure of the
said _Medulla_ thus taken out, and the _Nerves_, thence proceeding; and
that of several Animals, Dogs, Swine, Sheep.

He intermixes several Observations, touching the _Singleness_ of this
_Medulla_, against _Lindanus_ and others; its _Original_; vid. Whether it
be the Root of the Brain, or the Brain the Root of it: its difference of
_Softness_ and _Hardness_ in several Animals; where he notes, that in
_Swine_ it is much softer than in Dogs, &c.

He exhibits also the Arteries, Nerves, and Veins, dispersed through this
_Medulla_, and inquires, Whether the _Nerves_ proceed from the _Medulla_ it
self, or its _Meninx_; and discourses also of the _Principle_ and
_Distribution_ of the Nerves; referring for ampler information in this and
the other particulars, to that Excellent Book of the Learned Dr. _Willis_,
_De Anatome Cerebri_. {398}

_Advertisement._

_It was thought fit to publish here_ the following _Advertisement_ of
_John Evelyn_ Esquire, and that, as himself proposed it. _Viz_,

Being much solicited by many worthy Persons, to publish a _Second Edition_
of my Discourse and Directions concerning _Timber, &c._ which was printed
at the Command and by the Encouragement of the _R. Society_, I do humbly
request, that if any Person have any Material, Additions or Reformations,
which he thinks necessary either to the Part, which concerns the
Improvement of _Forrest-Trees_, or that of _Cider_, he would be pleased to
communicate his Notes and Directions to Mr. _H. Oldenburgh_, one of the
Secretaries of the said Society, at his House in the _Palmal_ of _St.
James's Fields Westminster_, with what speed they conveniently can, before
our _Lady-day_ next, to be inserted into this intended _Edition_.

_What was observed, _Numb. 20_. p. 364, l. 18, of the Number of
_Vegetables_,_ (_vid._ That they are about 410.) _found in _England_; and
catalogued by Dr. _Merret_ in his _Pinax_, &c. is to be understood only of
the _different Kinds_ of Plants, not of the several sorts of several
Plants; for, these being comprised, the Number will amount to about 1400._
