NEW ASTRONOMICAL EPHEMERIS. 



"Vl/ r E have to congratulate the public on the appearance of one of 

 » » the most useful publications in practical astronomy that has 

 ever yet been formed. It is an Ephemeris arranged in an entirely 

 new manner, computed on an entirely new principle, and adapted to 

 the present advanced state of that important science. 



Our readers are aware that, for the last fifty years, the celebrated 

 Bode conducted the Berlin Ephemeris with great credit to himself, 

 and with great advantage to astronomy. This work, inferior to none 

 on the subject, contained annually a vast variety of valuable informa-
