    THE heat conductivity of liquid helium II at 1·34 ° and 2·06 ° K. has been measured, by Dr. J. F. Alien, Dr. B. Peierls and M. Zaki Uddin, by means of a new method consisting essentially of a combination of a vapour-pressure thermometer with a liquid-helium manometer. The results show thai the heat conductivity of liquid helium II depends upon the temperature gradient, an unusual behaviour for which, the authors state, they can offer no explanation.
