following Tables. They form the first horizontal line for every value of u, 

 and are marked Ma. -when directly made out by the aforesaid maps. We 

 sulgoiu to them, in the second line for every u, and marked by Ca., the 

 corresponding- calculated values, which, according to the solution of our final 

 equations, as has to be shown hereafter, are at once conformable to theory 

 and the closest to the results obtained from the maps. 



Values of a or increments of Declination from 1784 to 1840.
