apparatus by the process; six times the division rate (see p. 478) 

 was relatively low. Five times this was synchronous with the 

 process; once with bacterial infection. 



The process occurred in Line VI and its subhnes at intervals 

 of about forty to fifty generations. For example, Line VI had 

 the process in progress at the 4231st generation, Line Vlf at the 

 4229th generation, and Line Vlh at the 4215th generation. 



The stages of the process which occurred in Line Vli in the 

 4279th generation and Line Vlh in the 4315th and 4355th gen-

eration, and in Line VIj in the 4312th generation did not show 

 any new features. Simultaneously with Line Vlh, Line VII 

 underwent the process in the 4355th generation. Line VIk was 

 killed after eleven generations, when the division rate fell slightly, 

 with the expectation of securing early stages of the process. 

 However the process was not found but judging by closely related 

 lines it would have appeared about twenty generations later. Line 

 VI together with its twelve branches and subbranches exhibited 

 the process a total of twenty-one times from the 4020th to the 

 4355th generation at clearly recognizable periods, showing that
