examined, this fact would at least necessitate reducing the degrees of freedom in 

 the denominator, in turn reducing the actual F-ratio value. In this case a de- 

 tailed examination of these F-ratios is superfluous, since the reduction would 

 have to be considerable before significance was marginal. 



To examine the semiannual oscillations, equation (2), for k = 2, was 

 fitted to each of the six sets of surface temperature data. The results are 

 summarized in tables 4, 5, and 6.
