 grouped or separate in the transparent gonidial cell, 

 where they already exhibit a certain amount of poly-

 internode, the wall of the latter gives way and they 

 pass into the water, where for a certain time they re- 

 main so active that it is almost impossible to describe 

 their form; but here and there, that which I have stated 

 may be seen in those which are less active in their 

 movements than the rest/ The elongated or spindle-
