 nuclear disc seen in profile ; b and d nuclear disc seen from tbe pole, in b the fibrils are 

 splitting longitudinally; e division of the nuclear disc into two; / separation of the two 

 halves of the nuclear disc; g two nuclei still connected by spindle-threads, in which the 

 cell-plate is forming ; h-vn division of the daughter-cells ; h and i, breaking up of the net- 

 work and formation of kinoplasmic spindle; fc spindle, in profile in the right, from the pleo 

 in the left; I separation of the segments, in profile in the right, from pole in the left; 

 in nuclei with connecting threads and cell-plates.
