APPENDIX 



Daily records of divisions 



Here are given the number of divisions per day for each file 

 of every line described in Experiment 1 of this report (the other 

 experiments are only summarized in the preceding pages). At 

 the end of every five days the total number of divisions for each 

 file for that period is given. The averages cited in the text are 

 obtained by adding the totals of the files of each line and divid- 

 ing by 20 (or the exact number of opportunities for division). 



A letter and number enclosed in brackets are used to designate 

 from what file an individual has been replaced after its loss from 

 death or accident, e.g. (A2). The symbol ° is used to indicate 

 that an individual died but was replaced by a sister individual 

 from the last preceding division of the same file. In this case the 

 number of divisions of the sister individual are credited to the 

 file, so 1°. The symbol - indicates a death without replacement.
