John Hunter, the famous surgeon,
argued $50 years ago that the skin OF all
men was originally black and that the
color gradually cleared away. Professor
Keith considers that this view is supported

suprarenals of the white man have de-
veloped the power to clear away the pig.

body have been noted when there was an
oyergrowth of the suprarenals. In such
cases there was no change OF color but
there was an abnormal gain in strength,
as when the thyroid is enlarged, but de-
yelopment that made them real supermen.
Professors Buloch and Sequeira noted
that a boy with overdeveloped suprare.
nails became tremendously full chested,
muscular. deep voiced, bearded--a minis
ture Hercules, marvel of power in brain
and body. Young girls with overdeveloped
suprarenals had very strong features, pow.
erful bodies and masculine characteristics.
Thus we learn that the suprarenais are
concerned in producing the most forcetul
types Of mankind, as well as regulating
color.
While II may be proved that the supra
renals determine skin color, there are still
many points about the origin of color to be
settled, for We have yet to learn why the
negro has one kind of suprarenal gland
and the white man a different kind. Sew
eral theories have been advanced as to the
origin Of color. Professor Lull, OF Yale,
in his work on Organic Evolution" says;
Celebration is doubtless dependent upon
the chemical material OF which any organ
ism is composed, and the hue is entirely
due TO the absorptive powers OF that sub
stance (through the innumerable pores OF
inner and outer skins). Since oxide Of
iron is red, so is the blood Of vertebrates.
Since oxide Of copper is blush green, so
is the blood of the octopus, and so on. In
many cases the color Of internal organs
may be due entirely to the nature Of the
food consumed. Thus, the flesh OF the
brook trout caught In Central Massachu-
sets, where there are few crustaceans
available for food, is pale, In the Adiron-
dack lakes, where the crawfsh Is abund-
ant, trout which eat It have a deep salmon
pink flesh. Thompson states that the pig.

In the tropics pigment is black. AS one

becomes brown, then yellow, and, finally,
white in Central Europe and equivalent
zones, where sun rays are minimized.
