[Ocular scale for logarithmic grouping of classes of spherical nuclei and measurement of the diameters of their nucleoli].
The proposed scale is prepared by a photographic method and consists of some vertical lines, each of them being disposed at the distance equal to a nucleus diameter having bordering size between classes of lg mkm2, and of three horizontal lines, forming two patterns designated for measuring diameters of nucleoli. The scale is meant for working with the objective 90 X and the ocular 20 X and makes the measuring of nuclei and nucleoli diameters 2--2,5 times quicker as compared with the screw ocular micrometer with a sufficient coincidence of results, obtained by both methods.
