being insensible. Hansen-Oluf sen's solar tables •were employed, 

 Stinive's constant of aberration, the solar parallax was assumed to be 

 8", 9, and new comparison stars were introduced whenever it appeared 

 necessary. By comparison with the observations the following normal 

 deviations - C were obtained : —
