New measurements on the vapour pressure curve of helium were made. They gave temperatures which throughout are slightly higher than those calculated according to the formulae which form the basis of the temperature scale 1932, to a maximum of 0.026 degree for helium II at 1.6 ~ K, and of 0.015 degre
