1. Southern Motion of the Fixed Stars. — In our last Num- 
ber, p. 393., we mentioned the Southern Motion of the fixed 
stars, which Mr Pond considers as deducible from his observa- 
tions ; and we stated, at the same time, that this discovery was 
not confirmed by the observations of the Reverend Dr Brinkley. 
Mr Pond has published another paper on the subject, in the 
Phil. Trans, for 1823, Fart. II. p. 529, in which he draws the 
same conclusions from the observations made at Greenwich, Ar- 
magh, Westbury, and Palermo. 
Dr Brinkley, we understand, has transmitted to the Royal 
Society an elaborate paper on tliat subject, by which he endea- 
vours to overturn Mr Pond's deductions, from Bradley’s ob- 
servations at Wan steed and Greenwich; Maskelyne’s at Sche- 
hallien ; Piazzi’s, at Palermo ; Mudge’s in England ; and Lamb- 
ton’s in Hindostan ; — all of which he considers as proving an 
uniform variation in declination. 
Having had an opportunity of seeing Tables illustrative of the 
subject of the southern motion, and highly interesting in several 
other points of view, which, we are informed, camfe from Dr 
Brinkley, we have obtained permission to publish them.
