The following elements obtained by Mr. Graham of Markree Ob- 
_ Servatory, from observations of Dec. 17, Jan. 20, and Feb. 17, accord 
temarkably well with those obtained by Professor Encke from the first 
two weeks’ observations.

_ It is gratifying to learn that Mr. Hencke has received various honor- 
able testimonials for his discovery of this planet. The King of Den- 
mark awarded to him a gold medal with the inscription, Ingenio et Arti. 
_ The King of Prussia also awarded to him a gold medal; and conferred 
upon him the order of the Red Eagle, IV, with an annual pension of 
three hundred dollars. E. L. 
- 6. Biela’s Comet.—In our May No. we have given some information 
Tespecting the extraordinary phenomena of this body. It was attended 
by a companion like a secondary comet, which was very remarkable 
for its changes of magnitude and brilliancy. This companion was no- 
, ticed at Washington, Jan. 13, and this is the first notice of it we have 
Seen from any quarter of the world, except the observation at New Ha- 
Ven, Dec. 29, 1845. At Cambridge, Eng., the phenomenon was first 
- ‘Noticed Jan. 15th, though the first measurement of distance we have 
Seen was for Jan. 23. On the 15th of January also, M. Wichmann at 
Kénigsberg noticed a faint nebula near the comet; and on the 26th, 
Perceiving that the distance between the two bodies had changed, he 
commenced a series of measurements. At Naples the companion was 
first noticed Jan. 19; at Berlin, Jan. 27; at Geneva, Feb. 3; and at 
. Feb. 13, 
~ The following observations give the differences of Right Ascension 
and Declination of the two bodies. They were all made at Wash-
