Three hundred and forty-second meeting. 

 January 29, 1851. — (Quarterly Meeting. 



The President in the chair. 



The nomination list was taken up, and the following gentle- 

 men were chosen Fellows of the Academy : — 



Hon. George P. Marsh, of Vermont ; 



Rev. William Jenks, D. D., of Boston ; 



Prof. William A. Norton, of Brown University, R. I. ; 



Prof. Charles B. Hadduck, of Dartmouth College. 



Professor Peirce stated that he had found the empirical 

 correction of the theory of Saturn, which he communicated 

 at the last meeting, to be confirmed by theory ; and that 

 the theoretical correction corresponded precisely in all its fea- 

 tures with the empirical correction. This correction recon- 

 ciles completely the discrepancy between the mass of Jupiter, 

 as it is determined from its action upon its own satellites, and 

 that which is derived from its action upon Saturn ; and it 

 now appears that this discrepancy did not arise from any error 

 in the great inequality, but from one in the largest term of the 

 periodical inequalities.
