Abstract: Apparatus for microscopic examination of a specimen includes a cylindrical test tube having a well, defined by closely spaced transparent flat walls at the closed end of the tube. A paddle-shaped insert has transparent insertable flat sided body at one end insertable into the well with a long stem extending out of the open end of the tube. The thickness of the body is slightly less than the spacing of walls of the well to spread specimen therein between and to support the specimen when the apparatus is placed in or on a microscope for examination of the specimen.
