resting nucleus. -The nuclear membrane persists until after 
metaphase and the nucleolus is present throughout the division, 
10. The primitive wall of the oospore first appears when the 
antheridial tube opens. . Later the epispore is laid down uponit 
by the periplasm. 
11. Two endospores are formed by the ooplasm after the 
development in the vacuoles of a peculiar substance which dis- 
appears as the endospores reach maturity. 
12. After the complete encasement of the oospore it becomes 
rapidly filled with food-stuffs. A large central oil-like drop is 
present during the winter condition, 
13. The fusion nuclei pass the winter in the resting comer 
without further perceptible change.
