272 THE PHENOMENON 01' 



extremely tninute green granules in it, as well as the 

 starch-grains* (not vanishing in the process of solution), 

 are taken up at the very first origin of the spores. They 

 are not gradually consumed, but enclosed in the first 

 structure, which also explains the phenomenon that the 

 spores do not commence with minute rudiments, and 

 gradually increase in size in the mother-cell, but, on the 

 contrary, are larger in the first epoch of their formation 

 than they are subsequently, when their mass has become 

 more condensed. Thus this case appears as a reformation 

 of the whole cell-contents combined with division, 

 peculiarly modified by the condensation of the newly- 

 formed cells, and the retraction from the wall of the 

 mother-cell connected with this, a retraction such 

 as we have also seen in reconstruction without division 

 in the spore of (Edogonium, or as we are acquainted with 

 in the family of the Zygnemacese (in the intermixture of 

 the contents of two cells to form one spore). 



E. Partial reconstruction through formation of 



DAUGHTER-CELLS IN THE CONTENTS OF SURVIVING MOTHER- 

 CELLS. — This kind of cell-formation is distinguished from 

 all the preceding bythe circumstance that the mother-cell is 

 not lost in the reconstruction, but survives the formation of 

 the daughter-cells, the contents of the mother-cell being 

 only partially, not entirely, applied to the formation of new 

 cells. While in all the foregoing cases the newly-formed 

 cells appear as more or less considerable transformations 

 of the mother-cell, we behold here a re-production or 

 new-formation in the most complete sense, since the old 

 cell persists as such, in spite of the reproductions taking 

 place in it. In all the foregoing cases, nothing remains 

 of the mother-cell after the formation of the daughter-cells 

 but the inessential membrane ; here, on the contrary, we 

 see the daughter-cells enclosed in the living, undividedly 

 persistent contents of the mother-cell. 



1. The daughter-cells originate {without a nucleus?) 



* Bach single spore encloses several of the existmg starch-grains in its 

 structure.
