What about using an ocular on the microscope that has the grid in 
the ocular? I found one on a scope in the morphometry suite.
 10 x10 squares on 10x or scanning should give you about the area 
you are looking for. You didn't say if the cells were fixed on the 
slide, but if not, what about a hemocytometer for counting cells per 
volume. Just  few thoughts.  Greg
