by mere water." But who will draw hence the conclusion of the Professor
with regard to the fluid used on the Collier folio, that it is "a
water-color paint rather than ink,"--unless "ink" is used in a mere
technical sense, to mean only a compound of nutgalls and sulphate of
iron?[aa]

[Footnote aa: The effect produced upon the brown ink on the margins of
the Guazzo by the mere washing it for a few seconds with lint and warm
water may be seen in the word "_apollegy_" on folio 25, reverse, of that
volume, which, with the others noticed in this article, will be left
for inspection at the Astor Library, in the care of Dr. Cogswell, for a
fortnight after the publication of this number of the _Atlantic_. This
slight ablution, hardly more effective than the rubbing of a child's wet
finger, leaves only a pale yellow stain upon the paper.]

Now it should be observed, that, among all the fac-similes published of
the marginal readings in Mr. Collier's folio, there are none either
so modern or so antique in their character as the five fac-similes
respectively given above; nor is there in the former a variation of
style approaching that exhibited in the latter, which all surely
represent the work of one hand. Neither do the fac-similes of the folio
corrections exhibit any chirography more ancient, more "Gothic," than
that of the account a specimen of which was published in our previous
article upon this subject,[bb] and which could not have been written
before 1656, and was quite surely not written until ten years later.
