A CLASSIFICATION OF GROUPS 301 



Since members of the same species are more alike than they are 

 different, it must be true, or expected, that the laws governing 

 their habits of behavior, and the combination of these, and their 

 succession will generally be the same, particularly when good 

 reasons can be assigned for apparent deviations from the above 

 assumption.

For purposes of convenience the second record of observer S 

 is reproduced below in the order in which it was made or beat. 



33, 27, 74, 87, 83, 45, 128, 23, 258, 27, 256, 39, 54, 240, 15, 176, 124, 

 58, 22, 154, 57, 20, 248 



The following facts are of interest in connection with the 

 work of observer R. Observer S beats the 27 group twice and 

 its double, the 54 once; the 128 group and its double, the 256 

 group, and also the group 258 which differs from the double of 

 the 128 by two beats, making it very likely a variety of the 

 128 or 256 group species; the 22 group and the multiples 176 

 and 154; the 124 group and its double, the 248 group. In this 

 respect then, the present observer does not differ from ob-
