The resistivity at 20°C of zinc crystals made of Kahlbaum's purest and of "Spectroscopically Pure" zinc (from New. Jersey Zinc Company) is given as a function of direction of current flow relative to the orientation of the crystal lattice. For the Kahlbaum crystals the results are very much more consistent than have previously been obtained and point to a higher ratio of p11/p1 than that obtained by Bridgman. The "Spectroscopically Pure" crystals agree in the main with the Kahlbaum, but there are a few exceptional cases which tend to confirm Bridgman's strain theory. It seems more probable, however, that an explanation can be given in terms of the conditions governing the growth of the crystals.
