The mean error of summing up of the above twenty-eight triangles is 

 three minutes, or one minute to each angle. 



The triangles were corrected by distributing the errors among the 

 angles, taking due account of the circumstances connected with the 

 measurements at the different stations. On all these stations monu T 



"■Station 79 is the point established by this triangle.
