The chromatin of the reconstructed daughter nuclei is often 
largely confined to the periphery of the nucleus, and nucleoles 
reappear. In the prophases of the second division there is a 
conspicuous development of fibers, and in this division it is 
not difficult to find pronounced multipolar stages in the forma¬ 
tion of the spindle. The fibers are again characterized by an 
unusually clean-cut appearance; they envelop the chromosomes 
in a dense tangle, and at their distal ends they come together 
in numerous places to form sharply pointed poles, each of 
which consists of relatively few fibers (Fig. 13). Frequently 
the poles are somewhat curved. The upper spindle of Figure 
13 is cut to one side, most of the chromosomes lying in the 
next section. The completed spindle again is a well defined 
figure. It is more slender than that of the first division, and 
the poles tend to be somewhat sharper, but the individual 
fibers stand out with the same distinctness and take the same 
brilliant stain as in the first division. 
The orientation of the spindles of the second division shows 
some interesting variations; as is frequently the case in the 
second division in spore mother-cells, the two spindles lie at 
various angles to each other. In some cases the two spindles 
•and the starch mass lie in three parallel planes. The axes of 
the spindles may then be parallel to each other, at right angles 
to each other, or at some intermediate angle. In other cases, 
however, the plane of one or both of the spindles is at an angle 
to that of the starch mass, and then it frequently happens that 
the plate-shaped starch mass is somewhat deformed. Figures 
14 a and 14 b represent two successive sections of such a cell; 14 a 
lies above 14 b. The lower spindle lies in the plane of the sec¬ 
tion, and ordinarilv the starch mass would lie some distance 
above it, also in the plane of the section. In this case, how¬ 
ever, the upper spindle is at an angle to the plane of the sec¬ 
tion, the right hand pole lying lower, the left hand one higher, 
and the starch plate has been depressed on the right hand side 
of the cell. The starch plate apparently continues to form a 
rather complete separation between the spindle-figures of the 
second division until late in the anaphases of that division.
