Mrs. E. II. Hartman Makes Gifts
Mrs. E. H. Hartman, widow of the
late railroad magnate, has given an
additional $4,000 to the fund of $780,
900 she established in 1911 for the
foundation of a meteorological and
pathological research laboratory, in
connection with the hospital service
of the Southern Pacific company This
announcement has been made by Dr.
F. X. Ainsworth, chief surgeon of the
railroad, in whose hands the disposi-
tion of the funds is placed. The pur-
pose Of the endowment is to further
the progress of medical research. For
the last two years the work has been
geing on under the direction of Dr.
w. T. Cummings of the Southern Pa
cific general hospital at San Fran
cisco. DR.. Cummings has deveoted
his time to study of serums with
special relation to typhoid fever and
tuberculosis, and has contributed
some valuable experimental data to
the existing store of scientific knowl-
edge. The fund is placed in the hands
of the Union Trust company of San
Francisco the income being turned
over to the hospital department as 1t
accrues. This is the second large
contribution to the Southern Pacific
hospital service within the last two
years, the widow of the late Coils P.
Huntington having given $25,750 for
the construction of social hall now
in use at the San Francisco hospital.
Every One Partly Color Blind
Various tests for color blindness
have come into practical use in the
examination of railroad engineers and
the like, where the ability to distin-
guish colors is necessary, so that
these tests are no longer peculiar to
the laboratory, but it is not generally
known, outside the laboratory, that
everybody is partially color blind
that is, in certain parts of the field Of
vision. The most normal Individual
can see all the colors only when he
looks directly at them If looked at
from an angle of about Is degrees red
and green can no longer be seen, but
in their places will appear shades of
yellow and blue. This region Of the
eyes is known as the yellow-blue zone.
If the color be moved farther to the
side the yellow and blue will disap-
pear and only gray can be seen, This
region is known as the zone of com
plete color blindness.
An interesting theory in regard to
these zones is that every normal eye
represents three stages Of evolution.
The zone of complete color blindness
is the lowest stage, and appears in
such animals as the frog, whose Wis
ion is known as shadow vision. The
blue-yellow zone is one step higher in
the scale, although not clearly marked
off in the animal kingdom, and the
appearance of the red-green zone
marks the highest stage of evolution.
Cases of color blindness are, accord
ing to this theory, lack of develop
ment beyond the early stage in the
individual life.-Strand Magazine.
Seeking New Route
The engineering department of the
Santa Fe is working on possible
route to connect Oceanside with Te-
mecula, The surveying crews have
been over the ground through the
Temecula canyon near Fallbrook and
up by way of Red mountains, Mon
sterate and Bon Bonsail. The cost
of replacing the road. that years ago
was wiped out of existence by a
flood, for heavy traffic, it is said,
would be greater than a new route
over the mesa by way of Bonsail.
That the road is to be connected up,
giving Oceanside and San Diego di-
rect connection with the Perris val
