nuclei varies considerably ; cells with one and two nuclei are 

 most common, though as many as three or more may be 

 present. 



Many of the forms furnish indications of the occurrence of

budding cells, and chains of cells, very similar to the egg 

 chains of Pfliiger.* 



Amongst the Vertebrata, multiplication by budding or 

 germination is very common ; in this mode originate the

mulberry-shaped masses found in the testes of many of the lower 

 animals. Annular constriction of the nucleus, similar to that 

 which precedes division, may frequently be observed, especially
