A CLASSIFICATION OF GROUPS

FIG. 5 



Figure 6 agrees with the preceding figures except respecting 

 the particular groups concerned. The groups are the 22 and 71 

 (70 + 1) plus the usual interval for the interpolation of a 2 

 group. It is therefore an attempted synthesis of a 95 group 



(94 + 1).

Figure 7 corresponds to two groups 46 and 71 (70 + 1) plus 

 an interval into which but one beat may be interpolated. Con- 

 sequently it represents an attempted synthesis of a 118 group, 

 a group which is beat as such twice by this observer. 



The above are examples selected from 15 occurrences of the 

 same kind in the work of observer R. In a certain sense they 

 must be regarded as quite accidental because they occur rela- 

 tively infrequently and consequently they cannot always be 

 relied upon, except under pre-arranged conditions, to furnish 

 objective evidence and proof for conditions that might be indi-
