THE SAYEE OBSEEVATOEY. 



Applying these corrections to the differences of consecutive groups given on page 

 389 we obtain the corrected differences, viz. : 



I- 



II-

 -I- .054 

 -|- .107 

 -I- .104 



— .142

Therefore we have 



I = II + -096 



III — .144 



IV — .124 

 V — .099 



VI — .127 



VII — .07^ 



VIII -I- .034 



IX + .138 



X — .004 



XI — .061 



Adding .033 to each group in order to make the algebraic sum of these corrections 

 zero, we (hid the following series of values which are applied to the results from the 

 different groups to reduce all to a homogeneous system : 



I + .033 VII - .040 



II -I- .129 VIII I .007 



IX + .171 



III — .111 



IV — .091 

 V — .006 



VI — .094 



X + .029 

 XI — .028 



Final Values of the Latitude. 



In the final results which follow, all known corrections and reductions have been 

 applied. The tabular statements seem to require no further explanation. The folding 

 sheet gives the individual results as derived from each observation. The probable error 

 of a single determination, derived from these values and therefore including the 

 outstanding error of the adjusted declinations, is as follows :
