| Figure 55 shows the spireme segmented and split longitudinally. | 
| At first it is quite small, and it gradually increases in size during the spireme stage. | 
| This body is often applied to the nuclear membrane and connected with the spireme. | 
| In figure 107 one sees the spireme divided into segments still joined by linin bridges. | 
| The connection of the element x with the spireme up to the stage where the spireme segments to form the bivalent chromosomes. | 
| The spireme here, as also in figure 99, is fine and closely interwound. |
