N2g goes right after things
and gets them done in a hurry, q
matter of no little pride to the
people who inhabit these United
States. But now comes an erudite
scientist, DIR. Austin O'Malley,
and says that American hustle is
not thing to brag about because
it is not a virtue, but form of
nervous irritability produced by
the ultraviolet rays in the sun
light that prevails in Uncle Sans
dominions. The doctor, who has
given toe subject a thorough in
vestigation, finds that we're it not
for immigration, the population of
this country would eventually con-
sist of brown-skinned people only,
as all the blonds would die off. 1t
appears that the latitude in which
practically the entire area of the
United States is situated is un-
suited for the Irish, English,
Scotch, Germans, and all other
north Europeans, because it is too
far south, and that the only peo-
pie able to survive indefinitely are
those who come from southern
Europe and points south. From
South Carolina to near Canada is
the zone in light and summer heat
for the olive-tinted white man, the
Mediterranean type" he says, and
this man thrives here fairly we'll,
despite the winter, which is more
severe than that of his European
home. If, however, a man from
Scotland, which has an average of
259 cloudy days in the year and a
very slanting sun, migrates to
Yuma, Arizona, where there are
about nineteen cloudy days an
nually, very slightly slanting
sun, and sometimes a temperature
of 12O degrees Fahrenheit in the
shade, he is stimulated for a short
time, then nervously exhausted.
and. finally, degenerates rapidly"
In an article in the Philadelphia
Public Ledger DIR. O'Malley sets
out his ideas regarding the develop
ment of the characteristic colora-
ton of the different races of man
kind, and the relation this bears to
the environment of the region
where each race has its original
home. We read:
Anthropology and tradition
show us the earliest man was
white, and that he lived at about
the latitude of the Euphrates
Basin. The colored and blond
races were such by development.
As the white man migrated south.
ward he slowly acquired protec-
tive skin pigment and became
brown. Farther south, in the
tropics, he grew black to defend
himself from the ultra violet rays
of the sun and to radiate heat
more readily. As he migrated
northward he lost the protective
pigment which was worthless to
him, and became whittier, so that
he could retain animal heat better.
Physicists that work with extra
spectral rays, Roentgen rays.
Becquerel rays, rays from radium,
and the like emissions must pro-
tect themselves by rubber. lead
glass, sheet lead. and similar
means. The ultraviolet radiation
changes the protoplasm of cells SO
as to let in salts which disintegrate
and kills the cells. There were
more than twenty physicians killed
in the United States alone by the
action of the x-ray before methods
for protection we're devised. Sim
liar rays exist in the sunlight.
Finsen, in Denmark. found that
skin pigment can protect animal
tissues from the ultraviolet rays
of the sun. Therefore. the stronger
and more direct the sunlight upon
