The plasma ball completely divided into small globular bodies. x 300. c. Cyst ruptured, showing exit of active spores, having long tail-like prolongations. After a time these become stationary; they retract their tails, and protrude instead a number of pointed irregular processes. In this condition, they are true amoeboid creatures, still without vacuoles or nucleus in their homogeneous body substance. a few fine granules were left scattered through the otherwise perfectly homogeneous protoplasm mass. Then, in the course of a day or two, and after it had retracted somewhat from the hyaline capsular wall., traces of segmentation revealed themselves in this.
