probable errors, except the single observation of 1690, made 
stead. This observation was in error 20”, according to Le 
computations, and 50” according to those of Mr. Adams; while 
astronomers agreed that Flamstead had made a very poor observation. 
Prof. Peirce’s orbit represents this observation within a single sec

When Le Verrier was allowed a carte blanche to create a planet to suit | 
his convenience, when he was at liberty to assign it any mass, and ; 
e it move in any orbit he pleased, he could not explain the obser- 
vation of 1690; but the planet discovered at Berlin, having a mass 
such as is deduced from Mr. Bond’s Mara area and moving in the 
orbit also deduced from observation, explains every thing perfectly. If 
then this mass is confirmed by subsequent rebate var and there is no 
mistake in Professor Peirce’s — (and we know no reason to dis- 
trust them ») the problem of Uran ems exhausted. The plan 
covered by Dr. Galle perfectly Satine the observed ineq 
Uranus, and these observations afford no reason to suspect th
