_Observables upon a _Monstrous Head_._

[Illustration]

This was the Head of a _Colt_, represented in the annexed _Figure_ 4. first
viewed by Mr. _Boyle_, who went into the Stable where the _Colt_ lay, and
got the Head hastily and rudely cut off, the _Body_ thereof appearing to
his Eye compleately formed, without any _Monstrosity_ to be taken notice of
in it. Afterwards he caused it to be put into a Vessel, and covered with
_Spirit of Wine_ thereby chiefly intending, to give good example, together
with a proof, that by the help of the said _Spirit_, (which he hath
recommended for such Properties in one of his _Essays_ of the _Usefulness_
of _Natural Philosophy_) the parts of _Animals_, and even _Monsters_, may
in _Summer_ it self be preserved long enough to afford _Anatomists_ the
opportunities of examining them.

The Head being opened, and examined, it was found.

_First_, That it had no sign of any _Nose_ in the usual place, nor had it
any, in any other place of the Head, unless the double Bag CC, that grew
out of the midst of the forehead, were some rudiment of it.

_Next_, That the _two Eyes_ were united into one _Double Eye_, which was
placed just in the middle of the Brow, the Nose being wanting, which should
have separated them, whereby the two Eye-holes in the Scull were united
into one very large round hole, into the midst of which, from the Brain,
entred one pretty large _Optik Nerve_, at the end of which grew a great
_Double Eye_; that is, that _Membrane_, called _Sclerotis_, which contained
both, was one and the same, but seemed to have a _Seam_, {86} by which they
were joined, to go quite round it, and the fore or pellucid part was
distinctly separated into two _Cornea_'s by a white _Seam_ that divided
them. Each _Cornea_ seemed to have its _Iris_, (or Rain-bow-like Circle)
and Apertures or Pupils distinct; and upon opening the _Cornea_, there was
found within it two _Balls_, or _Crystalline Humours_, very well shaped;
but the other parts of it could not be so well distinguished, because the
eye had been much bruised by the handling, and the inner parts confused and
dislocated. It had four Eye-browes, placed in the manner exprest in Figure
4. by a a, b b; a a representing the _lower_, and b b, the _upper_
