Normal Equations. 



The equations constructed from the coefficients in the column of sums furnish the annexed 



results : 



x = 0".1408 0".2667 

 y = -f- F.3134 0".0698 

 z = + 0".1904 0".1439 

 w= 0".3843 0".1139 



The Altona observations being but two in number, while four unknown quantities are to he 

 determined, it is of course impracticable to deduce the measure of their precision from internal 

 evidence. After some little examination, the most appropriate weight seemed to be unity, and 

 they are consequently combined with the other results without modification.
