ere are too few observations in any one of the last series, 
to give any marked indication of the periodicity noticed in the 
results obtained by the first method; but nevertheless, series 
, on analysis, shows a tendency to break into three groups, 
differing by six and a half vibrations. Thus:

It is very improbable, to say the least, that certain values 
should be selected and certain others be rejected in this way 
without some cause beyond that of mere accident. 
The period, it will be noticed, differs somewhat in different 
individuals but is almost constant in the same individual. The 
doubling may be caused by the obliteration of one of the nor- 
mal groups, or as it appears sometimes, by the rejection of the 
intermediate values. ;
