Abstract
WHEN discussing our observations on the transfer of liquid helium II along solid surfaces above the liquid level1, we pointed out that this mechanism of surface flow might also be responsible for the 'transport phenomena' in the bulk liquid (high heat conduction, low viscosity and the fountain effect)2. Subsequent experiments by ourselves3, Allen and Reekie4 and by Kapitza5 strongly support this assumption. It appears that the transfer film observed above the liquid level also extends below it, covering all solid surfaces in contact with liquid helium II, and it is evidently in this film that the anomalous transport phenomena take place.
