N1 - Funding Information:
The specimens a~eevaporated on substrates of size 00 microscope cover glass, one layer of thickness d~,and either one or two layers of an alloy of lead with 5 per cent bismuth, about 2000A thick. Two Allen—Bradley thermometers * Supported by the National Science Foundation and the Rutgers University Research Council.

N2 - Thermal conductivity measurements on double and triple layers of thin films of silver and a lead-bismuth alloy have been used to determine the energy gap in the silver. In double layers and dirty triple layers the gap is the same as the observed in tunneling measurements. In clean triple layers a smaller gap is observed as a result of the low energy excitations travelling parallel to the interface. An analysis leads to the conclusion that the electron-electron interaction in silver is attractive, with (NV)Ag = 0.1.
