FORMATION OF THE FINAL EQUATIONS. 



16. Formation of the final equations for the period 1845, taking into 

 account the equations of condition for (X), (Y) and (Z) to (c) inclusive, and 

 also the equations (P) corresponding to the polar segments with radius 12 30'. 



The final equations will be as follows : 



For m = and n odd,
