like so many blades of _Fern_. Having taken several of these plates out of
water on the blade of a Knife, I observ'd them figur'd much after the
manner of _Herring bones_, or _Fern blades_, that is, there was one bigger
stem in the middle like the back-bone, and out of it, on either side, were
a multitude of small _stiriæ_, or _icicles_, like the smaller bones, or the
smaller branches in _Fern_, each of these branches on the one side, were
parallel to all the rest on the same side, and all of them seem'd to make
an angle with the stem, towards the top, of sixty degrees, and towards the
bottom or root of this stem, of 120. See the fourth _Figure_ of the 8.
_Plate_.

I observ'd likewise several very pretty Varieties of Figures in Water,
frozen on the top of a broad flat Marble-stone, expos'd to the cold with a
little Water on it, some like feathers, some of other shapes, many of them
were very much of the shape exprest in the fifth Figure of the 8. _Scheme_,
which is extremely differing from any of the other Figures.

I observ'd likewise, that the shootings of _Ice_ on the top of Water,
beginning to freez, were in streight _prismatical_ bodies much like those
of _roch-peter_, that they crost each other usually without any kind of
order or rule, that they were always a little higher then the surface of
the Water that lay between them; that by degrees those _interjacent_ spaces
would be fill'd with _Ice_ also, which usually would be as high as the
surface of the rest.

In flakes of _Ice_ that had been frozen on the top of Water to any
considerable thickness, I observ'd that both the upper and the under sides
of it were curiously quill'd, furrow'd, or grain'd, as it were, which when
the Sun shone on the Plate, was exceeding easily to be perceiv'd to be much
after the shape of the lines in the 6. _Figure_ of the 8. _Scheme_, that
