560 General Notes. [June, 
the investing sac bursts and a countless host of germs is poured 
forth. The growth of these germs into forms like the parent was 
continuously watched, showing gradual enlargement and ulti- 
mate, but as to time somewhat uncertain, appearance of the nu- 
cleus, and the somewhat sudden appearance of the flagella or 
thread-like motor organs, the latter being found in each instance 
to arise in the nucleus. Very soon after the adult stage is reached 
the act of self-division commences, and is kept up for hours in 
succession. The delicate plexus-like structure becomes aggre- 
cation of division of the body-substance. Quickly afterwards the 
nucleus becomes completely cleft, and the body-substance follows 
suit. Then the plexus-like condition is again diffused equally 
over the whole nucleus. When the generative condition 1s ap- 
proached by the last generation of a long series of dividing forms, 
it is remarkable that the organism becomes amceboid, showing 
such forms touch one another, they coalesce and fuse into each 
other almost as though two globules of mercury had touched, until 
nucleus reaches nucleus and two melt into one, and the blended 
bodies become a globular sac, which ultimately emits an enor 
mous number of germs. Previous to the blending it is now made 
out that all traces of plexus-like structure are lost in the nucleus, 
After giving similar details about several other organisms, es 
Dallinger summed up thus: “One thing appears clear, the 2
