sperous or unequal of all Colours, and so
like, that 'tis very hard to distinguish them, but Black is the most Rough
of the two, Green is next in Asperity, Gray next to Green in Asperity,
Yellow is the fifth in degree of Asperity, Red and Blew are so like, that
they are as hard to distinguish as Black and White, but Red is somewhat
more Asperous than Blew, so that Red has the sixth place, and Blew the
seventh in Asperity.

12. To these Informations the Obliging Doctor was pleas'd to add the
welcome present of three of those very pieces of Ribbon, whose Colours in
his presence the Blind man had distinguished, pronouncing the one Gray, the
other Red, and the third Green, which I keep by me as Rarities, and the
rather, because he fear'd the rest were miscarry'd.

13. Before I saw the Notes that afforded me the precedent Narrative, I
confess I suspected this man might have thus discriminated Colours, rather
by the Smell than by the Touch; for some of the Ingredients imployed by
Dyers to Colour things, have Sents, that are not so Languid, nor so near of
Kin, but that I thought it not impossible that a very Critical Nose might
distinguish them, and this I the rather suspected, because he requir'd,
that the Ribbons, whose Colours he was to Name, should be offer'd him
Fasting in the morning; for I have observ'd in Setting Doggs, that the
feeding of them (especially with some sorts of Aliments) does very much
impair the exquisite sent of their Noses. And though some of the foregoing
particulars would have prevented that Conjecture, yet I confess to you
(_Pyrophilus_) that I would gladly have had the Opportunity of Examining
this Man my self, and of Questioning him about divers particulars which I
do not find to have been yet thought upon. And though it be not incredible
to me, that since the Liquors that Dyers imploy to tinge, are qualifi'd to
do so by multitudes of little Corpuscles of the Pigment or Dying stuff,
which are dissolved and extracted by the Liquor, and swim to and fro in it,
those Corpuscles of Colour (as the _Atomists_ call them) insinuating
themselves into, and filling all the Pores of the Body to be Dyed, may
Asperate its Superficies more or less according to the Bigness and Texture
of the Corpuscles of the Pigment; yet I can scarce believe, that our Blind
man could distinguish all the Colours he did, meerly by the Ribbons having
more or less of Asperity, so that I cannot but think, notwithstanding this
History,
