Abstract
The general problem of the convection of heat from bodies immersed in moving media has recently received considerable attention both from the theoretical and experimental point of view. The equation of the conduction of heat in a moving fluid was stated by Fourier as long ago as 1820,(

) and a few years later was expressed by Poisson(

) and Ostrogradsky(
