3 ‘Novara’ entries in this portion of the Zone are those moBt distant from the Mean Epoch. The only land station of the ‘Novara ’ is Gibraltar. The latitude 
;itude of Gibraltar are so near to those of Malaga that it seems quite justifiable to apply to the ‘ Novara’ result, at the first-named station, the secular change 
>ns employed at the last-named station by so high an authority as Lamont, viz. 7 ,- 5 Declination and 2' m 7 Inclination annually. These rates have been 
;d by Dr. Lamont’s own directions, in reducing his observations to the epoch of 1842, in the preceding and present Papers (Nos. XIII. and XIV.).
