The lengths variedfrom about 3 cm to cm. Fig. 6 shows a photograph of two ofthe specimens in the copper holders. In making the specimens from commercial ice a rectangularpiece was first sawed from the selected solid block. By planingwith an ordinary ice shaver this was worked down to a cylinderof the required diameter, which was then sawed into the lengthsdesired. A hole was drilled through the principal axis of eachspecimen and enlarged to proper size by running tap water. Afew of the specimens, which were dried mechanically at the melt-ing point, were left solid. The ice which was frozen in the cylin-drical copper can was obtained in the form of a hollow cylinderand required only to be sawed into the desired
