12 The Mycetozoa, and 



The life-history of our organism may be briefly 

 summarized in the following diagram, hi which the circle 

 shows the essential stages of life, and the outliers show 

 occasional and non-essential stages. 



We wish to dwell a little more on some of the points of

 order from that previously used. We started with the 

 sporangium, as the most easily grasped and the best known
