puscles. Within the entoplasm of the processes vacuoles, 

 food-residua, and excrementitious granules resembling crys- 

 tals are also found. Among the vacuoles one exhibits pul- 

 sation, undergoing contraction about every fifteen minutes. 

 The nucleus is about one-fifth as large as the resting ameba. 

 The pseudopods of adjacent bodies frequently unite, and 

 there thus result plasmodia consisting of as many as forty 

 segments. Multiplication takes place through division or 

 budding. Leydenia belongs to the rhizopods. Von Leyden 

 expresses himself with reserve in regard to its etiologic 

 significance.
