Hence the annual decrease of the dip in Dublin (or 8 e) is 
2’, 38. 
The close agreement of this result with that recently 
deduced by Major Sabine, from his observations at the 
Regent’s Park, is very remarkable. From these observa- 
tions it appears that the dip has undergone a diminution of 
39’ at London, in the interval between August 1821, and 
November 1837, an interval of 164 years. The annual de- 
crease, therefore, is 2’.40.
