✦ Synopsis

The critical point for the onset of convection (BBnard point) was determined for the system CHBrZGHBr2 -CHCl2XHC12. No stabilizing effect was observed. Experiments which sampled this and a conventional thermal diffusion cell (cf. following letter) to directly measure the concentration gradient due to thermal diffusion revealed that the madient was destroyed when the solution is heated from beLow. This is an unexpected and important observation.

lllzatlon was observed as predicted by phenomenological arguments. This effect is due to the thermal diffusion separation which gives a negative contribution to the gradient of density.
