is 60509,12 fathoms ; and the mean degree for latitude 
l6° 34.' 42", as deduced from the arc between Namthabad and 
Daumergidda is 60512,78 fathoms, which exceeds the com- 
puted one for latitude i6°34' 44" (which may be considered 
the same) only 3,66 fathoms.

will bring out a compression equal nearly, which differs 
considerably from the general mean. But a very small dif- 
ference in the numerator will produce a great difference in 
the compression.
