Each has a partition at its base, separating the twooriginall}^ distinct cells, and each was lined with a cocoon,showing that it had been used for rearing young. At g, notonly has the partition between the combining cells disappeared,but also three of the sides of eacli cell. Tlie bees do not appear to have any sjstematic way of mak-ing a transition from worker to drone cells, which are one-fifthlarger than the former. More commonly, they eflfect it by agradual alteration of the diameters, thus enlarging a workerinto a drone, or narrowing a drone into a worker cell. Thisalteration is usually made in from four to six rows. In one case APIARI^. 127 Professor Wyman noticed the transition made with only onecell, as in Fig. 78, but not without destroying the regularit} ofthe two adjoining rows.
