M. Carlini has remarked it as a curious circumstance, that though 

 the distance of the comet from the sun was increasing, the light of the 

 comet was increasing also. 



On the 1st of January, 1825, its right ascension will be 75 q 8' its de- 

 clination 47* 5' north, the log. of its distance from the sun 0.2618, and 

 the log. of its distance from the earth 9.96207. Zach. Cor. Astron. vol. 

 xi. p. 196. — Phil. Mag. vol. lxiv. p. 309. 



2. The Buenos Ayres Comet oj 1821. — The observations on the comet 

 which we mentioned in our last number, vol. i. p. 37, as very suspicious, 

 have turned out to be an imposition. M. Encke of Seeberg has been at 

 the trouble to compare the Buenos Ayres observations with Dr. Brink- 

 ley's elements of the comet of 1821, observed by Captain Basil Hall, 

 and the result is, that the observations are false. Baron Zach very ap- 

 propriately remarks, that if the other transactions of that country re- 

 semble this, the new republic of Buenos Ayres will soon take the road 

 of the comet. 



3. Spots on the Sun in 1 824. — About the end of May, M. Flaugergues 

 observed on the west limb of the sun a very large spot about to disap- 

 pear. From that time till near the end of August he had not observed 

 any spots whatever on the sun's disc. M. Pons of Marlia observed a 

 fine spot on the sun on the 26th of May, and surrounded with a penum- 

 bra like Saturn's ring. He saw numerous white spots on the sun's disc. 



4. Lohrmann's Maps of the Moon. — M. Lohrmann, Professor in the 

 Military Academy at Dresden is about to publish an Atlas of Lunar 

 Maps, which will represent the whole surface of the lunar globe with 

 an accuracy and precision beyond any thing that has yet been attempted. 

 Baron Zach has seen the first section of these maps containing a part 

 of the Mare Nubium, of the Mare Faporum, and of the spots named Ptole- 

 my, Hipparchus, Albategnius, &c. which he considers as executed with 

 infinite care and accuracy. 



5. La Place on the Masses of the Planets. — In a new edition of his 

 celebrated work entitled Exposition du Systeme de Monde, which has 

 just appeared, he has given the following new measures for the masses 

 of the planets : 



New Masses. Old Masses.
