Two independent low temperature scales, based on noise thermometry below 0.6 K and on extrapolation from 1.5 K using magnetic thermometry, have been realized and compared. Both scales coincide at the pressure minimum of the He-3 melting curve within +0.3 mK and determine its temperature as 315.1 mK.

On the basis of the vapour pressure of 3He--4He mixtures, partly measured directly by S o m m e r s and by W a n s i n k et al. and partly calculated from the osmotic pressure data obtained by W a n s i n k and Taconis, the change of the Gibbs-function of the mixture with concentration has been calc
