OPPOSITION OF MARS, 1851-52, 



DECEMBER 33, 1851 Continued. 



Remarks. 



An extremely fine night, definition superb, and motion steady. The line bounding the zone is evidently darkest near the western limb, and the 

 zone itself apparently smaller than when first seen. There is no star in the place given in the Ephemeris, and an error of a minute in the declination 

 was probably made in Bessel, or in the Washington observations. 



a Wavy motion in these two observations.
