characteristic clear area. I liave not been able to make out 

 the precise method of origin for the caryosome. 



The entire number of six chromosomes can usually be seen 

 when a polar view of the telophase group can be had, such as is 

 shown for the lower nucleus in figure 30. The complete number 

 is also seen in the side views of figure 31. Kuczynski ('14) 

 likewise shows six in a similar stage in his figure 66 of T. muris. 

 His figures 64 to 67 and 69 also show well the constriction of the 

 anaphase and early telophase chromosomes that I have mentioned. 



Since the telophase chromosomes appear to resolve themselves 

 each into two chromomeres, and since the earliest prophase 

 chromosomes which can be recognized as such are already double, 

 one naturally wonders if the two parts of a prophase chromo- 

 some may not be represented by the two telophase chromomeres. 

 Since the two telophase chromomeres are arranged end to end, 

 while the two parts of a prophase chromosome are arranged side 

 by side, and since the number of chromatin granules in the 

 resting nucleus is rather large and indefinite, the direct relation- 

 ship suggested is improbable. 



While the two daughter nuclei are becoming reorganized into 

 typical resting nuclei, complete sets of other organelles are being 

 established for the two new individuals. The origins of most 

 of these organelles have been discussed in connection with the 

 prophase. The chromatic basal rod and the flagella merely 

 complete a development initiated at the earlier phase. The 

 new axostyles, however, apparently do not begin to grow out 

 until the telophase. There is a suggestion of a new axostyle 

 growing out from the old blepharoplast in the early stage shown 

 in figure 29, but in figures 32, 33, and 34 the new axostyles are 

 distinctly seen. In figure 34 it will be noted that the new 

 axostyle growing out from the older, larger blepharoplast is 

 longer than the other one, as might be expected. It will also 

 be seen from these figures that there is a row of chromatic 

 granules along the new axostyles. These appear to be imbedded 

 in the axostyles and are probably intimately concerned in the 

 formation of these organelles. These granules must go to the 

 surface later or disappear, for they do not occur within the adult
