an axis inclined about 28° to the Ecliptic, and with its semi-axis sub- 
tending about 18”, so that the satellite is about 250,000 miles from the 
planet. It is much brighter in the preceding than in the following half 
of its path. The orbit which it appears to describe has a minor axis 
differing little from the diameter of the planet. The periodic time as- 
signed by Mr. L. accounts for all the etn de of the planet and 
satellite, Scocea by him since his discovery. observations in 1847, 
from Aug. 31 to Sept. 6, are quite conclusive as a the existence of the 
satellite. Mr. L.’s observations have all been made with a Newtonian 
reflector, constructed by himself, of 24 inches diameter and 242 inches 
focal distance, using magnifying powers of 205 and 370 
This satellite has also been seen by the aid of the Grand Refractor, 
at Cambridge, Mass., and Mr. Bond has published his observations 
thereon of Oct. 25, 27, 28, 1847. In the course of these observations, 
the oh pi of another satellite fainter and more distant, was strongly

Ina sigs dated Cet. 26, 1847, to the Editor of the Boston Courier, 
Prof. Peirce remarks, “the mass of Neptune corresponding to Mr. 
Lassell’s result, is equal to that of Uranus, so that with this mass, one 
half that of Leverrier and Adams, it cannot account for more than 
forty of the one hundred and eighty seconds of the unexplained irreg- 
ularities in the motion of Uranus.” 
In regard to the ring, nothing ebeviwiely: certain is sh oiexminay 
but Mr. Lassell has no doubt of its existence

The manifest, various advkatiges of this resort pinto with me the 
otherwise too serious objections to it on the score of singularity. i
