That tlie obtained values of the corrections of the incHnation as well as of 

 the node must be attended by great mean errors appears from table XXVII. 

 The mean errors of the values of y^, computed from the entire material, are given 

 in the last column of this table. These mean errors are all of the size of O'.O30, 

 and are thus rather great in proportion to the variations the latitude motions are 

 subject to, during the course of the year. The corresponding mean errors of the 

 values of computed from the motions in one liemisphere only, during one of the 

 periods in question, will thus be of the size of about O'.oeo. These values of 

 being the direct basis of the computation of AL sin / and A/, one must, as above 

 mentioned, positively expect also these corrections to be attended by considerable 

 mean erroi's.
