m. Ber. t., A. R. 64° 0' 23-6, Dec. 12° 39’ 53/1. The star is retro- 
grading like a planet near its opposition. é ENCKE. 
The new planet was observed at Altona and Hamburg on the 17th; 
at London and Cambridge on the 24th; at Pulkova on the 26th; at 
Bonn, Jan. 2d ; and from this time it was followed at nearly all the ob- 
servatories of Europe. The following are. the observations made at 
Berlin, as far as they have been received.
