ASTRONOMICAL SOCIETY. 



The Third Anniversary Meeting of this new association, 

 which is rapidly advancing in importance and prosperity, was 

 held at the Society's Apartments, No. 55, Lincoln's Inn Fields, 

 on Friday the 14th of February last. At this meeting, a report 

 from the Council was read, stating, among other matters, that 

 the Society now consisted of 187 effective members and asso- 

 ciates, including the greater number of the eminent astronomers 

 of Europe ; that the funds were in a flourishing condition ; and 

 that great progress had been made in establishing an astronomi- 

 cal library, which would shortly be opened for the use of the 

 members. A just tribute of respect to the memory of the 

 lamented President of the Society, was likewise paid in this 

 report, as well as to those of Sir Henry Englefield, Dr. Hutton, 

 M. Delambre, M. Tralles, and several other valuable members, 

 of whom the Society had been deprived by death during the 

 past year ; and it concluded by calling upon the members and 

 associates, generally, to promote the objects of the Institution 

 by every means in their power, and particularly by the transmis- 

 sion to the Society of such papers and observations a3 might 

 become useful by their registry and comparison. A minute 

 investigation of the heavens was also recommended to be 

 effected by dividing them into small portions, each to be exa- 

 mined by an individual member.

March 14.— Several new members were proposed, and others 

 elected. A considerable number of astronomical books were 

 presented to the library of the Society ; and two papers were 

 read. The first was a demonstration by means of a functional 

 equation, of the result of two forces acting upon a particle of 

 matter; communicated by Dr. Miekleham, late Professor of 

 Astronomy in the University of Glasgow. The second was
