measles TO the monkeys The expert
ment had been attempted in England
and elsewhere. but had failed At our
national laboratory, however, the blood
or serum used to inoculate tho mon
keys was taken from the human patti
ent at just the time that tho rash was
coming out or was about to como out.
II carried the disease. and from this
and other experiments we now know
Just when measles arc Infectious
The first monkeys were inoculatod
juno of last year Ten uays later
they began to be fevcrish, and an erup-
tion camo out upon them, just as IL
does on child. Tho little animals
developed all the symptoms ana fea-
lures of human measles and the dis
case acted in the Same way Now
when the disease was Just at the right
point certain OF these monkeys wero
killed and their blood was used to In
oculate fresh monkeys The monkeys
SO iuoculated took the measles, and a
third set of monkeys inoculated with
their blood took the measles likewise.
Dangers to School Children.
From these and other cases DR..
Anderson finds that the period OF in
feetivity> from measles. as far as the
monkey is concerned. begins about the
fourth day after he catches the dis
case, and that it disappeared as soon as
the eruption has passed away and the
temperature of the patient becomes
normal. 1t must be the same vita
humans. but As it is now, when a child
has the measles it is kept out OF
school for something like three weeks
THESE INVESTIGATIONS show that twelve
or fifteen days time is all that Is
necessary, and it is probable that a less
period would be safe. Tho disease is
communicated from man TO man. or
rather from child to child. FOX 1t is
to a large extent child's disease. by
means OF the sccretionS which come
from the nose ami mouth. Certain
monkeys which were inoculnted with
q fluid mixed with these secretions
took the measles, and ii is probable
that tho contaGion comes largely from
such secretions. The saliva and other
sccretions are mixed with the dust OF
the streets and thus taken into the
system. For this reason children with
the measles should BE- warned against
eXpectoration.
Monkey studies of Infantiic Paralysis,
Among others ot the recent invcsti-
CATION OF the hygienic laboratory is
lntantilc paralysis. This dread dis
ease is Ike the measles in that 1t
usually attacks little children 1t is
disease OF the spine. which paraiyzcs
the child either in part or In certain
OF its members. and which often causes
death. In Sweden out of 59a eases of
children under eleven seventy one died,
ana in Massachusetts in 62S cases the
state Board OF Health found that 10
per cent. of tho babies OF less than
one year failed 10 receiver. Among
the others. who got partially we'll. -four

Infantilo paralysis is not new dis.
ease Evidences OF II have been found
in AN Egyptian mummy which is al.
most 5000 years old, ana it has long
existed in Europe There have been a
number OF outbreaks of 1t IN various
parts of the United States within the
past few years. Massachusetts had
one In 1907, 1905 1909 and 1910. Mtchi.
gan one In 1907 and 1905. Pennsylvania
one in 1910. and Oregon, South Dakota
and Virginia were afflicted with il dur
ing that same year. 1t was In 1910
that it broke ont here in Washington,
resulting in $50 cases. and about SIN
teen deaths. The Youngest case was
only four months old and the Oldest
siXty-four years.
In studying this disease there have
been many attempts to give II to
guinea pigs. rabbits. horses, sheep.
dogs. cats. chickens. ducks and pigs.
They have all failed. but IL has now
been discovered that IL can he given
to the monkey. and also that monkey
which has had the disease once can
not be given the disease again. 1t has
