For, if we consider
first, the very _faint light_ wherewith the object is enlightened, whence
many particles appear _opacous_, which when more enlightned, appear very
_transparent_, so that I was fain to _determine_ its _transparency_ by one
glass, and its _texture_ by another. Next, the _unmanageableness_ of most
_Objects_, by reason of their _smalness_, 3. The _difficulty of finding_
the desired point, and of _placing_ it so, as to reflect the _light
conveniently_ for the Inquiry. Lastly, ones being able to view it but with
_one eye_ at once, they will appear no small _obstructions_, nor are they
easily _remov'd_ without many _contrivances_. But to proceed, I could not
find that water, or some _deeply ting'd_ liquors would in small ones rise
so high as one would expect; and the _highest_ I have found it yet rise in
any of the pipes I have try'd, was to 21 _inches_ above the level of the
water in the vessel: for though I found that in the small pipes it would
_nimbly enter_ at first, and run about 6 or 7 _inches_ upwards; yet I found
it then to move upwards _so slow_, that I have not yet had the _patience_
to observe it above that height of 21 _inches_ (and that was in a pretty
_large Pipe_, in comparison of those I formerly mentioned; for I could
observe the _progress_ of a _very deep ting'd liquor_ in it with my _naked
eye_, without much trouble; whereas many of the _other pipes_ were so _very
small_, that unless in a _convenient posture_ to the light, I could not
perceive _them_:) But 'tis very probable, that a greater _patience_ and
_assiduity_ may discover the liquors to _rise_, at least to remain
_suspended_, at heights that I should be loath now even to _ghess_ at, if
at least there be any _proportion_ kept between the height of the ascending
liquor, and the _bigness of the holes_ of the pipes.
