This paper is concerned with the flow of heat in the low-field mixed state of two single crystals of niobium: Nb4, of resistance ratio about 300; and Nb5, of resistance ratio about 1300. In the temperature range covered, 0.4–1.2°K, heat flow in the Meissner state of these crystals is due entirely to phonons.1 Preliminary measurements on these crystals have already been reported by us2; in the present paper we report certain aspects of our latest results that are of particular interest. A full account will be published elsewhere.
