Abstract: A fecal examining device comprising a closure member in the form of a tray adapted to be fitted upon the open lower end of a solution-receiving receptacle or cylinder, said closure member or tray including a central, open-top cup that extends into the cylinder for a short, predetermined distance. A cap is provided for closing the open top of the cup or well when the tray is not attached to the cylinder. A perforated piston is provided for manual movement within the cylinder to thereby separate ova from the fecal material in solution.
