duced by the BY tae of the karth; by J. N. SrocK WELL. 
Havine been engaged, during a number of years past, ina 
Pen and systematic examination of the physical theory of 
€ moon’ S$ motion, it seems proper to make Known to astrono- 
mers, in advance of the publication of my researches which are 
now essentially completed, one of the most curious and interest- 
ing results at which I have arrived relative to the motion of 
our satellite. 
a has been known, since the time of Newton, that the attrac- 
n of a spheroidal body on a point ey its surface is 
ies from that of a eet having the sa ass the
