REMARKS. 



1. The numerals following the names of discoverers indicate the 

 number of asteroids detected by each. Dr. Peters, of Clinton, X. Y., 

 has discovered twenty-six ; the greatest number first seen by any one 

 observer. 



2. The numbers discovered in the several months are as follows : 



January 10 



February 11 



March 13 



April 24 



September 30 



October 14 



November 18 



December 3 



The weather is favor- 



May 14 



June 7 



July 8 



August 20 



This obvious disparity is readily explained, 

 able for night-watching in April and September; the winter months 

 are too cold for continuous observations; and the small numbers of 

 June and July may be referred to the shortness of the nights.

 i, the inclination; tt, the longitude of the perihelion; and fj, the longitude of the ascending node.
