Slicing Animal Tissues

By means of the microtome slices of vegetable and animal tirues down to i thinness of about l-1000.h of an inch are obtained for microsc?pic study. Professor Elmer Gates of Washington bas now gone further and even slices ap blood cells and microb-8 by cementing them in a single layer between two Klaas slides and cutting the slides apart with a very thin blade of copper sharpsned to the highest possible degree. The fine grain of the copper causes it to take an edge that no razor can approach. The cells are agaln cut by ropeating the operation, and it is claimed that slices have been made only l-100th as thick as the thinnest produced by the microtome.
