Some Startling Facts.
These startling facts were made
public today by Doctor Barnett
Sure, Department Of Agricultural
Chemistry, College Of Agriculture,
University of Arkansas, whose re-
search activities In this connection
are attracting universal attention,
in an address before the American
Society for the Advancement Of
Science.
Doctor Sure, discoverer OF VIZ.
amin E, necessary for reproduction,
declares that the greatest propor.
ton of mortality among human
beings takes place between the ages
Of one and three; and among in
fants the greatest losses Of babies
occur during the first year Of life
during the nursing period.
Undoubtedly the cause Of such
fatalities among human Eabies
must be attributed to either Insult.

Controls Secretion.
Heretofore the relation between
faulty lactation and the diet has
not been appreciated. 1 am now

duce either sterility Of fertility

ton to such an amazing extent
that l can induce mothers to pro-
duce healthy young or poorly
formed young; live babies or dead

to one-third Of the nursing period,
two-thirds of the nursing period, or
that will be weaned successfully.
Insufficient milk flow in the hus
man mother is not the unusual
thing 1t Is rather the usual
thing, and, therefore, the medical
profession has been, in the ma
jority of cases, absolutely handi-
capped in its efforts to help moth
ers successfully to nurse and wean
their children because of a lack
of scientific understanding of the
dietary needs during the nursing
period"
Doctor Sure hopes that the way
will soon be open to help many
mothers along this line.
The milk proteins were found by
Doctor Sure to be excellent Cor
growth, thus corroborating the
work of McCollum and his associ.
ates. But even in the presence of
an abundance of all the dietary
constituents, including all the
known vitamins, milk proteins
were found inadequate for repro.
duction. Doctor Sure, therefore,
started out to find the cause.
One Cereal Grain.
The addition of one cereal grain,
or one legume seed, although add
ing insignificant amounts of known
dietary factors, always brought
about fertility and in some cases.
a certain amount of success in rear
ing young. A new dietary complex
existing in natural foodstuffs and
absent in purified diets was then
postulated by Doctor Sure.
The new vitamin, named Vita
min e by Doctor Sure, its dis
coVerer, has been traced to certain
vegetable oils in recent investiga-
Ntions. It was established that
certain kinds Of oil-containing
seeds retained normal powers of
reproduction, wherefore Doctor
Sure undertook to find what part
of the seeds contained the vitamin.
He separated the oily substances
from the starchy bulk Of the seeds
by extracting with ether, benzine,
or acetone, and then distilling off
the solvents.
Animals fed on starchy residues
were unable to reproduce, but
others fed on q diet containing the
extracted oils brought forth young
in normal fashion.
The oil extracts thus far used
by Doctor Sure in HIS experiments
have been taken from yellow corn,
wheat embryo and hempseed. From
work so far completed, Doctor
Sure tentatively classifies the veEe.
table oils into the four following
groups:
Oils Produce Fertility.
Those oils that do not even pro.
duce fertility. These include com.
mercial linseed, cocoanut and
sesame oils.
Those oils that produce fertility,
but fall in lactation or milk secretion
and nursing of young In that group
Is commercial olive Oil and the oil
of the peach kernel; also peanut and
soy bean oils directly expressed.
Those oils that produce fertility
and are partly successful in lactation
In that group, so far as studied, Doc.
Or Sure lists cotton-seed oil.
Those oils that are potent for botl,
fertility and successful lactation.
2 In that group are wheat.germ oil.
corn oil, and henpseed oil, prepared
by extraction with ether, benzine, OF
acetone.
Vitamin e is indispensable for both
fertility and lactation, but In the same
series OF experiments Doctor Sure
