The data shown in Table II show that a uniform distribution of cells is maintained, within experi- mental error. Samples were removed for counting at periodic intervals over a span of two hours to determine the rate of cell removal. Cell counts were made on a Wild microscope at 10 X 40 power using an American Optical Neubauer 20 40 60 Time (minutes) 100 FIGURE 2.
