were when fresh, I do
not feel that I have quite solved. The following palette scheme seems to
me about as near as the data permit us to formulate.

A permanent black, being the parts reproduced in black in the present
edition.

A brick-red, tinged with crimson, used for backgrounds, red numerals,
and probably elsewhere. This we may call unfading red.

A genuine brown, as on the animals, pages 5-a, 8-a; perhaps also
elsewhere as lining ornament.

A pale pink as flesh color on the human figures.

A blue, as on the possible katun number series on pages 23 and 24.

A turquoise-green, with varying amounts of blue tinge, on the spotted
figures and in the numeral columns of pages 15 to 18; also, with
somewhat less of the blue, for the "water" bands on pages 21 to 24.

The above colors are all definite and positive.

Then next appears a brownish color used for lining or ornamenting
various glyphs, and the clothing, headdress, etc., etc., of the figures.
We find many shades from a pale neutral up to a darker clear brown, and
also a definitely reddish, as on the tail of the bird on the right side
of page 23. This brown may be a fading of the red of the backgrounds and
numerals, but the permanence of the color in these latter places is so
positive that I believe it is not so. I think it should be regarded as
separate.

We next come to a color question related directly to decipherment, that
of the very difficult numeral columns on pages 15 to 18. There is no
practical reason discernable for the use of alternating colors save the
avoidance of confusion between bar combinations. Three bars together of
different colors stand of course for three 5's; of one color they would
make a single number 15. We therefore find here our above black, red and
blue-green alternating and clearly marked in places; but we also find
many numerals of varying shades of brownish, bistre and grayish. I
called for especial care in the examination of these points on the
original Codex, and the water-color sheets and explanatory notes show in
detail the facts of the present state of the Codex. Prior to the
examination I supposed that these faded numerals were a faded red, but
this is stated in the report to be certainly not the case; the
suggestion is made that they are probably faded blacks.

From the latter conclusion I am inclined in part to dissent, at least as
to certain passages, for two reasons. These are, first the actual
permanence of the
