Fig. 32. Early interkinesis. 
Fig. 33. Later. Chromosomes distinct, but to all appearances as yet unsplit. 
Fig. 34. Late interkinesis. Chromosomes have split, and halves have bent around 
each other. 
Fig. 35. Metaphase of the homoeotypic mitosis. X 1,140. 
Fig. 36. Granddaughter nucleus, soon after formation. Chromosomes are beginning 
to lengthen and to send out delicate projections, which later fuse to form a network. 
Fig. 37. Chromosomes are rapidly losing their identity, as their contents pass out 
into the projecting threads. 
Fig. 38. Resting stage in a granddaughter nucleus. Chromosomes are entirely 
obscured.
