In regard to the effect on the different elements, as shown in the foregoing tabular 

 statement, it is to be remarked that, while the changes in the major axis, velocity, 

 and eccentricity were cumulative, and would at length, if continued, have rendered 

 the orbit parabolic and then elliptical, those in the longitude of the perigee were 

 oscillatory, the motion being direct in the 2d section, where the meteor was approach- 

 ing the perigee, and retrograde in the 3d section, where it receded from it, and so 

 may not be at variance with the conclusion arrived at by La Place, in his investiga- 

 tion of Encke's comet, that a resisting medium does not permanently affect the posi- 

 tion of the line of apsides of an orbit. Another fact noticeable in this connection,
