348 J. F. ENCKE ON THE METHOD OF LEAST SQUARES. 



iiber das Gesetz des Falles, ^c.,' by J. F. Benzenberg, Dort- 

 mund, 1804, — although the reasons given for the exclusion 

 of others are perhaps not quite convincing. Designating the 

 easterly deviation from the perpendicular by + , and the westerly 

 by — , the foUov^'ing deviations in Parisian lines were observed 

 in a height of 262 Parisian feet. 



If X designates the deviation sought, the simple form of the 

 equations of condition is here 



x — n = 0; 



consequently, according to (13.) the most probable deviation is 



and the errors remaining over, arranged according to their abso- 

 lute magnitudes, are, m ^
