that are hard to explain. For in
stance. have in mind a man who
al the age Of % began to get gray
hair and at the same time devel-
oped augmented spots on the eye
lids and neck and arms-plgment
loss one place, pigment increase
another. Some have CRAVING only
Of the eyebrows, the hair on the
head and elsewhere on the body
remaining in its original condl-
ton.
The vitamin studies on prema-
turely grazing hair have been
made only on a few animals
rats, dogs and silver foxes. Other
animals, including man, are re-
sistant. By shaking watery so
luton of liver extract, yeast, or
rice bran with fuller's earth, sew
eral vitamin r factors (thIamine,
ribofavin, pyrioNine) are removed,
leaving a solution Of the "fltrate
factor
Animals fed with diet contain
:5S <sh@S. y,t2cA,Hs but lackluS
this fltrale factor show patches
Of fur that has become gray and
thinned, and the skin becomes thin
and wrinkled as in old age. On
adding the filtrate factor, these
symptoms clear up in most cases.
Attempts Unsuccessful
The filtrate factor is known to
contain pantothenic acid and
para -amino-benzoic acid. But at
tempts to determine which Of
these is responsible for the pre-
vention of CRAVING hair have not
been successful. Some expert
mentors report that removing
pantOthenic acid causes premature
graying and restoring it to the
diet causes return of pigment;
others report the same effects with
para-amino-benzoic acid. There is
possibly another factor or factors
yet undiscovered in the filtrste
factor.
Little work has been reported
on human beings. One derma-
tologist, giving large amounts Of
B complex fortified with para-am-
ino-benzonic acid, reported that in
800 patients with premature gray
ing within three to eight weeks
the hair became yellowish and
then dark gray.
Seldom Show Change
But others have tried it with no
noticeable results. 1t depends q
good deal on the personal equa-
ton. 1t has been shown that it is
very easy to deceive even the most
conscientious judges on the color
OF hair or skin, especially the
slight changes which would be de-
noted in changing from gray" to
dark, dusty gray"
In the latest report by DR., Bran
deleone and colleagues 10 pa
tients were studied by photo
graphs and clipping Of specimens
before and after giving the filtrate
factor and in only 2 cases was
there any change al. all.
Besides it again goes TO show
that animal experiments with vi
tamins and endocrine products
cannot be translated over to hu-
man beings. Some animals are
very susceptible to vitamin de-
fciency-for instance, rats that
have for generations been scav-
engers and used TO very varied
diet. Rabbits and guinea pigs on
the contrary used to a monotonous
and not very nutritious diet do not
respond to vitamin experiments at
all quickly.
QUESTIONS AND ANSWERS
l.. F. M.:-What is the best
method of protecting the ears
when engaged in target practice
with small arms rifles and
pistols?
Answer: There are many ap-
planes devised for this purpose,
but the use of a cotton pledget
moistened with glycerine is about
as good as any. don't know what

everyone is advised to keep the
mouth open during the detona-
