A circular cover-glass, mm. thick, is fitted centrally in this hole and is also fastened to the glass slip; thus an annular space is formed. In the middle of the cover-slip two sets of twenty-one parallel lines are etched which cut each other at right angles; there are thus formed a large square with a side of i mm. and small squares with a side of mm. The drop of liquid taken up by a pipette is examined on this square and enclosed by the cover- glass, the depth of the liquid layer thus formed amounting to mm. (Fig. 218).
