* These curious filaments have in some respects a centrifugal development : the cells 

 of the base, or next the axis, being the least developed as regards number of granules. 

 These, which are very irregular in size, are exceedingly mobile. The action appears to 

 cease at last from want of room, for the cells become literally crammed with the granu- 

 les.
