mum spacing between wires. This was pointed out by the writer ~ixteen years ago, 1 and H. B. Dwight has shown in a recent article 2 that if two parallel three-phase circuits are carried on the same pole line, the arrangement of Fig. 3 is decidedly preferable to the more usual arrangement of Fig. 4.
The effective thermal conductivities of silica aerogel foam [0.1 (10)-3 kg m -3 nominal density] filled with liquid n-H 2, liquid n-D 2 and an equimolar mixture of liquid H2-D 2 were measured near 19.6 K. Our measured value of 97 mW m -1 K -~ for hydrogen filled foam is essentially the same as for t
