In common with Gay Lussac and Davy, he held subterraneous thermic disturbances to be probably due to the contact of water with metals of the alkalis and alkaline earths.
The thermic group, exhaust system, control unit and mapping are specifically designed for track competitions.
The action is not due to any influence on the thermic centres, nor to any production of diaphoresis, but to the influence of quinine upon the stability of oxyhaemoglobin.
The irritants may be bacteria and their toxins, or they may be mechanical, chemical or thermic.
Conductivity.-Conductivity, whether thermic or electric, is very differently developed in different metals; and, as an exact knowledge of these conductivities is of great importance, much attention has been given to their numerical determination (see Electric conduction; and Conduction Of Heat).
