Samples were prepared by grinding small amounts in an agate mortar, They were then mounted in thin-walled glass capilIaries of 0.3-mm. diameter. Film patterns were recorded in a 114.6-mm.-diameter camera, using CuK radiation filtered through nickel foil ( A = 1.5418 A%.), The samples were rotated d:ving exposure.
