When it is desirable to discover whether a certain stain consists of blood, it must first be moistened with the white of egg, then scraped off the material holding it, and examined under the microscope with a quarter of an inch object-glass. If the stain consists of blood, blood-corpuscles will be rendered distinctly visible. Cancer-cells, should be studied under a power of at least 500 Fg. fi5. diameters, with a clear definition.

The nuclei of cancer-cells will be found enclosed in the cell, or floating free, usually more or less of both. The characters of the matter of cancer is as follows; 1. the nuclei with the nucleoli, which are very brilliant in the center; these nuclei alone are specific (See Jig. 65) they are exactly similar to those conFig. 66. tained in the cells. They usually contain one or two nucleoli, but there may be three.
