Observatory, Gosport, Mardi 1 "•

 degrees of the sun. It has only lessened its right ascension half 

 a degree, and its north declination four-fifths of a degree, since 

 the evening of the 24th of February, when it was first seen here ; 

 but by the annual motion of the earth, its distance from the sun 

 is decreased about IG". Now it is advanced too far in the solar 

 rays to allow us to make correct observations on its position. 



At the close of this month it will begin to set after the sun, 

 and with a clear horizon an hour before sunrise, there will be a 

 chance of seeing it rise about E.N.E. during the ensuing month. 

 The weather has lately been unfavourable for seeing the comer, 

 so near the western horizon in the evenings ; as, from its very 

 slow geocentric motion, it will not afford suificient space to at- 

 tempt to deduce the form of its orbit, which is the chief object to 

 science. 



It is hoped that correct observations on the frequent appear- 

 ance of thobc celestial visitors, will, in the course of time, throw
