• The twists of KCl tubular whiskers grown on KCl crystals have been measured by the Laue method using long slits. Excepting only one example, twenty-eight whiskers show pronounced twists amounting to about 0.1 to 0.7 rad/cm. It seems probable that a hole parallel to the axis of a KCl tubular whisker is a hollow dislocation and that it's twist is due to the screw components of the stress of the dislocation. The Burgers vectors of screw dislocations calculated from the measured twists using Eshelby's theory are larger than 100Å, and sometimes larger than 1000Å. Frank's formula for the hollow dislocation is modified in order to apply to tubular whiskers, and it is found that the modified formula agrees qualitatively with the experimental results.
