add a drop of methylene blue solution on to the smear and gently place a cover slip on top (to cover the stain and the cells)
3) any excess solution can be removed by touching one side of the slide with a paper towel or blotting paper.
4) place the slide on the microscope for observation using 4 x or 10 x objective to find the cells
5) once the cells have been found, they can then be viewed at higher magnificatio
