At each pole the threads of the spindle are connected with a granule of the cell protoplasm, tlie pole cor- puscle or centrosome, mentioned on a previous pa^-e; from the centrosome radiate numerous fine fibrillar, connecting the centrosome or pole corpuscle with the cell protoplasm, thus forming ' the suns ' or attraction- spheres, one at each pole (van Beneden). The above-named sister loops so arrange themselves about the equator of the spindle as to form a star— the motJier-star, monaster, or aster. In this arrange- ment the vertex of the loops is directed inwards, the open limbs outwards. Seen in profile the aster would appear like a narrow granular - looking plate of chromosomes—the nuclear plate. iv.—Metakinesis : Of each pair of sister loops form- ing the aster one loop is attracted by— migrates
