The equations are these : 



Equations from measurement of diameters. 



The solution of these equations gives the results exhibited, in the table below, chiefly as a 

 matter of curiosity and interest. 



It proves the attempt to separate the quantities t and u to be, at least in the present case, 

 altogether futile. The two last columns give the resultant value of t upon the supposition 

 u = 0, and that of u if t be ignored. 



Solution of equations derived from measurement of diameters.
