To obtain the number of cells per sq. dm. in a comb of given cell dimensions, use the formula: Number of cells per sq. dm. = 2.3 X N2, where N is the number of cells in one decimetre, measured horizontally (across the vertical sides of cells "right way up.") This formula is due to Signor G. Muzzati, and is published in the January number of L'Apicoltore d'Italia, (XV, No. 1, 1948).
