and which only a generous soul would entrust to a tyro to be used in

I managed without the assistance of the other three or four hands
which I should have had, to get the little imps rallied ground for
the Great Endeavor. Considering that they were not aware of the grav-
opportunity of the occasion and believed that it was simply another xxxxxx
for eating, they behaved very well. As there were three of them, all
in motion, it looked like a hopeless task. However, the boldest one
was not very hard to match with the charts, as his persistence kept
him pretty well in focus, and after getting him "calibrated" I could
use him as a standard with which to compare the others. After doing th
this, however, I found I could get pretty fair direct reading-s on the
others. I would say that the iris of No.1 corresponds to Ridgway's
Brownish Olive, Plate XXX, and that all of them may be considered
as having eye shades --just now--lying within the group: Brownish Olive,
Olive, Buffy Olive and Light Brownish Olive. The differences are very
slight. It should be noted that the Brownish Olive is the same shade
as Dr. Grinnell's suggestion of Sepia, but is two hues nearer the
green end of the spectrum in color.
If I interpret Ridgway correctly, this eye color may be regarded
as made up as follows: Beginning with Light Cadmium, which is a e
yellow hue of the orange of the spectrum or an orange hue of the yellow
of the spectrum lying xxxxxaaxxxxrxxxxxatxxxxxthe yellow than to the orange
of the spectrum made up of about 47% of orange and 53% of yellow, ad-
dition of 58 % of neutral gray gives his Honey Yellow (Pl.XXX).
Addition of 87.5% of black to this gives Brownish Olive. It will
appear as if there were no green in this, yet, whether it be due to
bias or other causes, Ridgway's Brownish Olive looks to me as if it
contained some green. I do not know how his printer got his blacks,
outward to it
but ordinary printer's ink is commonly based on lamp black or carbon
