Kennedy plunged directly from this
startling revelation into his proof.
Perhaps you have heard of the
famous German scientist, Weichardt
of Berlin he resumed. "and his re-
markable Investigations into the toxin
of fatigue. Scientists define fatigue
as the more or less complete loss of
the power of muscles to respond to
stimulation due to their normal ac-
tivity. An interval of rest is usually
enough to bring about their return to
some degree of power. But for COM
plete return to normal condition a
long interval may be necessary
AS the result of chemical changes
which occur in muscle from con-
traction, certain substances are
formed which depress or inhibit the
power of contraction. Extracts
made from the fatigued muscles of
one frog, for instance, when injected
into the circulation of another frog,
bring on an appearance of fatigue
in the latter Extracts from un-
tatlgued muscles give no such results.
More than that, the production of
this toxin of fatigue by the exercise
OF one set of muscles, such as those
of the legs in walking, greatly dimin-
ishes the amount of work obtainable
from other unusued muscles, such as
those of the arms"
Kennedy went on, looking at the
sleeping guinea pig rather than at us:
"Weichardt has isolated from fatigued
muscles a true toxin of a chemical
and physical nature, like the bacterial
toxins, which, when introduced into
the blood, gives rise to the phenomena
OF fatigue. This is the toxin of IA
tlsue-kenotoxln. Those who have
studied the subject have found at least
three fatigue substances-free sarcolatic
acid, carbon dioxide and monopotas-
SUM phosphate, which is SO powerful
that, after the injection of one-fifteenth
OF gram. the poisoned muscle shows
signs OF fatigue and is scarcely able
to lift weight easily lifted in normal
conditions. Other fatigue products may
be discovered but, if present in great
or IN small quantity for a long time
each OF the substances I have named
will cause depression or fatigue of
muscles
Further than that" continued Ken
nedy, the depressing influence of
these substances on what is known as
striated muscle-heart muscles well
known: The physician at the Idlewild
might very well have mistaken the
cause of the relaxation of Murchie' $
heart. For German investigators have
also found that the toxin of fatigue.
