good
fortune to secure a copy some ten years ago, and one other has recently
appeared in a Leipzig catalog at a high price. Beyond these I have not
traced any other copy.

In 1872 Prof. de Rosny published a reproduction, drawn by hand, which,
as stated by him later, may be disregarded for practical purposes.[7-*]

In 1887 he issued a facsimile edition in colors, 85 copies, which up to
the present time has remained the only attempt to show the Codex in its
proper colors, and has become exceedingly difficult to procure; so much
so that it was only after seven years search that I was able to secure
my own copy.[8-*]

In 1888 he reissued the Codex, uncolored, with the same letter-press,
and in an edition of 100 copies. This has also become scarce.

Each of these three editions has its advantages and disadvantages. The
colored edition of 1887, having been worked over by hand, in
lithography, is defective in various places, both as regards the black
of the figures and glyphs, and in the colors. Coloring exists on the
original codex which was not reproduced at all in the edition, and the
colors given are in many cases not exact. Thus on pages 19 and 20 two
different reds are used for the backgrounds, whereas but one is found in
the original; on pages 15, 16 the figures are a turquoise green, and on
pages 17, 18 an olive green, the correct color for all four being
turquoise green.

I have been able to find no inaccuracy in the 1888 edition, which is
indeed stated in the introduction to be entirely by mechanical process,
without hand intervention; but being reproduced by printer's ink in
black only, not only do the colors not appear, but the chromatic values
are actually far inferior to the photographs of 1864. It was stated
further by Prof. de Rosny that some features of the MS. had been lost by
deterioration in the 25 years previous to his editions of 1887 and 1888,
but this I have not been able to verify in any important point.

The photographs and the edition of 1888 are to all general purposes
identical; but, notwithstanding that the photographs are steadily
yellowing by age, the chromatic values are so far superior that I have
continually come to find them the court of final decision in doubtful
matters. In a very considerable number of instances a close examination
of the photographs has suggested the presence of faint lines of color
on glyphs or figures, which was entirely indistinguishable in both of
the printed
