turned towards the granosphere, all rays which do not strike 

 the granosphere must be counted as mantle fibers and polar 

 fibers and not as belonging to the central-spindle fibers (Figs. 

 41-47). In order to supply this matter to the central spindle, 

 the granosphere dissolves from the side that is turned towards 

 the central spindle and not from the opposite side. As the 



An auxocyte in the beginning of the anaphase. Only a few of the chromosomes are indicated. 

 At each pole there are respectively one and two archosomes and three and four accessory 

 archosomes. The chromosomes contain chromioles suspended in chromoplasm. At the 

 apex of each chromosome there is seen a chromoplast with endochromatic granules. To 

 the right and left in the cell are seen agglomerations of plasmosphere indicating the 

 position of the new cell wall, which is to separate the two daughter-cells. The chromo- 

 somes are seen to be connected with the centriole by contractile fibers, the latter con- 

 sisting of granules enclosed in a common sheath. The spindle fibers as well as the polar 

 fibers start from the centrosphere . 



central spindle grows in size, the granosphere is seen to dimin- 

 ish. The rays of the central spindle are also seen to end in 

 the granules of the granosphere, and the whole appearance is 

 such as to leave no doubt of the central spindle being fed prin- 

 cipally on the granules and secretions of the granosphere. On 

 the contrary, no such connection can at any time be seen 

 between the polar and mantle fibers on one side and the grano-
