Prof. Mosso, of Turin, has demon
Btrated the Importance of keeping the
surface and extremities of the body
warm during brain work by clearly
proving that where the brain is active
much more blood is sent to it from the
peripheral parts of the body. Prof
Mosso has also found that the circula-
tion of the blood in the brain is subject
70 fluctuations which are apparently
not dependent on physical tivity.
Fatigue caused by brain work acts as
poison, which affects all the organs,
especially the muscular system. The
blood of dogs fatigued by long racing
also acts as a poison, and when injected
into other dogs makes them exhibit all
the symptoms of fatigue. Sense of
fatigue seems to be due to the products
of the nerve cells rather than to the
deficiency of proper ubstance.-Illus-
