with, later on in twos and threes. There are as many leaders 

 as there are to be chromosomes. The leaders condense into 

 chromosomes. The leaders are connected with each other 

 only by the chromoplasts. 



Linin Granules or Grantda. — The smallest visible granules 

 composing the linin network and threads. Also found free in 

 the nucleus during the resting stage and after the prophases. 



Linin Network. — The congo-staining network supporting 

 all the chromatin structures during the prophases. 



Linoplast. — One or more round bodies in the nucleus, 

 staining like the linin and the cytoplasm. They supply the 

 material for the linin network, when this is in rapid increase. 

 Generally called true nucleolus. 



Linopodia. — The thread-like or bar-like projections from the 

 individual granules of the cytoplasm, and from the linin and 

 other granules of a similar nature. By these linopodia, the 

 individual protoplasmic granules are able to adhere to each 

 other and to form network or foams. These linopodia are 

 retractile, very much like the pseudopodia of the amoeba, but 

 they are more regular and even throughout their length. 



Mantle Fibers. — All fibers of the mitotic figure, which radi- 

 ate from the outer margin of the centrosphere, and which sur- 

 round the central spindle. The polar fibers and the contractile 

 fibers are not included in the mantle fibers. 



Metaplasfnic Secretions. — The various secretions confined in 

 vacuoles of the spheres. 



Mid-Body. — A number of darkly staining granules, situ- 

 ated on the fibers of the central spindle, at a place where 

 the two daughter-cells separate. They are probably caused 

 by a concentration of the cytoplasmic granules of the fibers, 

 separated and only suspended by thin threads of linin 

 (Fig. 64). 



Paracellular Bodies. — Bodies of various sizes and structure 

 found between the cells. They are probably expelled centro- 

 somes and particles of the spheres. Some are free, others 

 are attached to the cells by threads of protoplasm, 



ParacJiromatic Grannies. — Granules found in the nucleus 

 during the resting stage and in the immediate vicinity of the
