will be remarked, the process described is only applicable so long as 

 a continuous connection is preserved, between the stations of observa- 

 tion and the points observed. In the observations under considera- 

 tion, there occurs a blank space between points LII. and LIII 

 whence the metbod described was no longer applicable beyond the 

 former point. But it fortunately happens that LIII. and succeeding 

 points are observed from hill stations, whereat, as already mentioned, 

 the values of f are liable to but trifling variation. The mean value 

 of f in these cases was deduced in the ordinary way as mentioned at 

 para. 64. The following is an example of this method.
