Prof. Mosso, of Turin, has demon
srated 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 1t from the
peripheral parts of the body. Prot
Mosso has also found that the circula-
ton Of the blood in the brain is subject

not dependent on physical activity.
Fatigue caused by brain work acts as
