Washington. D. c. Nov. That the
color and texture OF a mans skin ana
hair, the form OF his features, his sta.
ture. the proportion of his limbs-an
OF his physical characteristics wsidh
mark him as belonging to certain
race-and many OF tro traits OF mind
and character which are associated
with those physical chara cteristIcs. are
regulated by half dozen small glands
in the body, IS ono OF the most ssNo-
lutionary OF the recent conclusions or
science.
This much Of tn. evidence Coz new
theory Is set forth by Arthur Keith,
British scientist. in an article recent
iy published by the srnithsonion IN
stitution in this country.
This new idea is revolutionary IN
more ways than one. II upsets the
old Darwinian theory OF sexual sell

the subject It shows that what we
call racial characteristics are by no
means confined to persons OF tho rae
with which they are associated. ln
persons OF the pure Nordlc strain there
may be Mongolian or Negro physiChl
characteristics. and they arc apt to pc
evidence OF mental and emotional
traits such as are associated Win
those races. In a word, hero !s new

Is certainly In some degree no=siple.
Scientists have already produced marx

administering the extract Of some OF
these glands. Thus disease known
as Myxoedema has been found to oe
due wholly to deficiency Of the thyroid
gland In Il the skin becomes dry
and often yellovtsh and the hair tends

thyroid controls IN some degree tho
development OF hair aud skin, which
arc race characteristics, Tho adminis-
trAtiou OF thyroid extract is a cure for
this disease.
The degree Of control which man
may attain over his own charscterls-
tics by his knowledge Of the ductloss
glands is limited chiefly by the factor
of receptivity Thus 1t has been quito
definitely proved that the suprareual
glands control pigmentation. Aud II
has been found that the action ot any
OF tho ductloss glads may generally be
regulated by administering an extract
Of those glands taken from the hodiud
OF animals. Gould then a black or

Is likely that the tissues Of the child
would not be sufficiently receptive OF

Each Of these ductless glands seems
TO have two sets Of activities In that
