Nemalion multifidum , Ag. 351 
Fig. 80. The tube is cut off, leaving a nucleus and chromatophore in the cyst. The division 
of the chromatophore took place previous to germination, x 2,140. 
Fig. 81. Nucleus undivided in the cyst. Chromatophore in the tube divides before the nucleus, 
x 2,200. 
Fig. 82. Prophase in the cyst nucleus. This section is cut obliquely so that only a small 
portion of the tube is shown. Such a striking prophase is not often seen in the cyst, and is probably 
due to the unusual amount of cytoplasm left behind, x 2,200. 
Fig. 83. Metaphase in the cyst, x 2,200. 
Fig. 84. Anaphase in the cyst, x 2,200. 
Fig. 85. The nucleus in the cyst has divided, but the daughter nuclei have not become com- 
pletely organized, x 2,200. 
Fig. 86. The two unorganized daughter nuclei in the cyst. A very usual condition, x 2,200. 
Fig. 87. Two unorganized nuclei and a chromatophore in the cyst, x 2,200. 
Fig. 88. Prophase for mitosis in the first tube cell, x 2,200. 
Fig. 89. Metaphase taking place in the tube before chromatophore division, polar structures, 
x 2,200. 
Fig. 90. Metaphase after chromatophore division. The more usual condition, x 2,200. 
Fig. 91. Anaphase in the tube cell, polar structures. Transverse section of the tube, x 2,200. 
Fig. 92. Telophase in the tube cell, x 2,200. 
Fig. 93. Previous to wall formation, x 2,200. 
Fig. 94. Two-celled stage of the tube. Third metaphase, x 2,200.
