OPPOSITION OF MARS, 1851-52, 



JAXTJARY 30, 1852 Continued. 



Remarks. 



Fine night. Any magnifying power may be used. Comparing star not brighter than 12J, or perhaps 11 magnitude, and so dim under light that a 

 large number of the measures are doubtful. Many were made witli no other light than that thrown into the field by the planet.
