•Since this point was established, the corresponding observations at Greenwich observatory have been furnished in manuscript by Prof. Airj', Astron 

 nomer Royal ; and the result deduced therefrom is Ih. 23»n. 35^.3, showing a difference of 115.2 from the adopted longitude. 



t Moon culminations also observed by Salazar, and resulting longitude found to correspond. W. H, B.
