PKEUM1NARY SOLUTIONS. 



VKM > II. 



Normal Equations. 



After one solution, the weight of the Cracow group was seen to be of a different order from 

 the weights of the other series, and the results of these Cracow observations were consequently 

 excluded. Solving anew, the following values were deduced, fully justifying the rejection : 



x = 2".6392 0".3711 

 y = 2".5401 =b 0".1265 

 z = + 0".7759 0".2192 

 W = 0".1066=b 0".1470 



The following weights, which differ but little from these, and resulted from u third solu- 

 tion, were employed in the final multiplication. 



Santiago equatorial. Santiago mrridlnn. Washington equatorial. Greenwich meridian.
