TABLE 1. 
Tus contains the length of the degree in fathoms with the logarithms, 
also of the minute and its logarithm. As the number of feet in I is 
the same with the number of fathonis m 1, divided by 10, it is evident 
the logarithm will be the same, with the exception of the index, which must 
be one less. For turning feet into seconds, the logarithms in column 7 
may be used.
