above the level of the lesion, thus raising the metabolism by only 50 per cent. Johnson
& Spalding (1964, 1966) confirmed these observations but their cervical patients did not
respond to cooling to such extent as was found in our experiments on rapid cooling.
It may be remembered in this connection that Sherrington (1924) cooled the hind limbs
of animals with complete transection of the cord and shivering occurred only in muscle
groups innervated above the level of the transection.
In hot air at 35-37°C, the two control subjects maintained a constant body tempera
ture, due mainly to evaporation of sweat. Tetraplegics, who do not sweat over the body or,
if so, only minimal, showed rapid rise of rectal temperature to 38-50 in i^ hr, when
panting and distress became apparent. Fig. I24d is a spirometer tracing of a complete

in the neutral environment and at 35-37 C and demonstrates the
increased rate and smaller tidal volume in heat.
