TABLE X.— Continued. 



Figure 14 shows log T plotted against log L, as in preceding cases. 

 The observations fall near to a straight line, A B, B C, as far as 50 

 miles. This line makes an angle of 45" with the axis of distances. 

 For the purposes of comparison a broken line ab, be is drawn through 

 the 2-mile record point at an angle of 48° 22' to correspond with 

 the lines in all of the other figures. The contrast is very noticeable. 

 Beyond 100 miles (1G0.9 kilometers) the points tend to follow the 

 direction of the broken line, but not with any degree of precision. 



The inference to be drawn from Table X and Figure 14 is that
