The Trigonometrical Survey of India. 
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whence the method described was no longer applicable beyond the 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. 61. The following is an example of this method. 
At Jagesar, IT. S. the values of 
(/) are 
.0448 5. 
.04528. 
.04876. 
Mean f adopted at Jagesar, H. S. .04630.

calculations may be tabulated thus.
