In the case of the quartiles, the indications are that the rate is 
more rapid in the first than in the second quartile, and that the rates 
in the third and fourth quartiles are successively more rapid than in 
the second. This does not appear clearly in the results from station 
D, especially when the returns from region 8 are included. Omitting 
the returns from region 8 (which is deemed legitimate, considering 
the comparatively short distance traveled, just 20 miles from 
station to the center of region 8) brings the results more 
nearly in accord with those obtained from stations A and B, the only 
disagreement being in the rate during the first quartile. This is, in 
the case of station D, slightly less, rather than greater, than the rate 
in the second quartile.
