I 
The degree of precision with which these constants represent the observations will 
appear from the number of errors between certain limits. W has from O'O to 0T0 
inclusive, 177; from 0T1 to 0-20, 72; from 0-21 to 0-30, 33; from 0*31 to 0-40, 3; 
above 0-40, 3. S has from 0-00 to 010, 172 ; from Oil to 0-20, 85 ; from 0-21 to 0-30, 
27 ; from 0 - 31 to 010, 3; above 010, 1. 
We now proceed to develop these constants in terms of <p ; but as four orders do not 
give K and K' with sufficient exactness, I have carried the formula to the sixth order, 
its utmost extent.
