| contd :- -2- SEE ORIGINAL FOR SKETCH. In order that we may further discuss the subject with R, we would like to have your views, and suggest that it might be wise for you to try experimentally to measure the temperature of the floor of a closed car when travelling at fairly constant speeds ranging between 20 and 40 m.p.h., and to try the effect of lagging on the silencer, and the shielding of the floorboards. It would be interesting to know how much of the heat comes from (1) radiation from the rear silencer, (2) convection currents from the rear silencer, and (3) hot air coming from the engine.
