ve_ Considerations and
hints, which perhaps may afford no despicable Assistance, towards the
framing of a solid and comprehensive Hypothesis, I have done at least as
much as I promis'd, or as the nature of my undertaking exacted. But another
thing there is, which if it should be objected, I fear I should not be able
so easily to answer it, and that is; That in the following treatise
(especially in the Third part of it) the Experiments might have been better
Marshall'd, and some of them deliver'd in fewer words. For I must confess
that this Essay was written to a private Friend, and that too, by snatches,
at several times, and places, and (after my manner) in loose sheets, of
which I oftentimes had not all by me that I had already written, when I was
writing more, so that it needs be no wonder if all the Experiments be not
rang'd to the best Advantage, and if some connections and consecutions of
them might easily have been mended. Especially since having carelessly laid
by the loose Papers, for several years after they were written, when I came
to put them together to dispatch them to the Press, I found some of those I
reckon'd upon, to be very unseasonably wanting. And to make any great
change in the order of the rest, was more than the Printers importunity,
and that, of my own avocations (and perhaps also considerabler
solicitations) would permit. But though some few preambles of the
particular Experiments might have (perchance) been spar'd, or shorten'd, if
I had had all my Papers under my View at once; Yet in the most of those
Introductory passages, the Reader will (I hope) find hints, or
Advertisements, as well as Transitions. If I sometimes seem to insist long
upon the circumstances of a Tryall, I hope I shall be easily excused by
those that both know, how nice divers experiments of Colours are, and
consider that I was not barely to _relate_ them, but so as to teach a young
Gentleman to make them. And if I was not sollicitous, to make a nicer
division of the whole Treatise, than into three parts, whereof the One
contains some Considerations about Colours in general. The Other exhibits a
specimen of an Account of particular Colours, Exemplifi'd in Whiteness and
Blackness. And the Third promiscuous Experiments about the remaining
Colours (especially Red) in order to a Theory of them. If, I say, I
contented my self with this easie Division of my Discourse, it was perhaps
because I did not think it so necessary to be Curi
