CHAPTER IX 



THE CONTINUOUSLY ZOOIDAL 

 INDIVIDUAL 



This type of Individual differs from the one last considered 

 in that its component zooids, when budded, remain attached 

 to each other, the Individual thus taking the form of a 

 branching zooidal " colony." In fact, it demonstrates for us 

 the next inevitable step in the evolution of living Continuity. 

 This may be illustrated by the addition of one more 

 diagram to those given on page 75.

Fig. 18. — Diagram of Continuity's evolution up to the Continuously 

 Zooidal Individual. 



In the figure above, A is the Discontinuously Multicellular 

 Individual ; each cell an independent organism. B is the 

 Filamentous Individual whose cells are united in linear 

 or Serial continuity. C is the Discontinuously Zooidal 

 Individual in whom the equivalents of cell-series or filaments 

 are united in Lateral continuity to form the tissues of dis- 

 continuous and independent organisms, the zooids. D is 

 the Continuously Zooidal Individual in whom, we may say, 

 the separate zooids of C have been obliged to develop in 

 Serial continuity. 



In other words, the discontinuity of A is " multiplied " 

 into the serial continuity of B, which in turn is multiplied
