Tt may be here remarked that in the latitude observations the 
annual variation of latitude has not been allowed for ; as, although 
its existence has been verified, its amount and period cannot as 
yet be considered as ascertained.* Effect from this cause upon 
the results obtained in the calculations about to be referred to 
will, however, be inappreciable. 
* Since the above was written, Dr. Chandler’s determination of an expression for the 
variation of latitude has been published. Dr. Chandler's value seems likely to need little 
f any modification, but it has not yet been used here.
