OPPOSITION OF MARS, 1849-50, 



Remarks. 



The night was not favorable for observations. Frequent cold blasts of wind, following a very hot day, generated currents in the strata of air. There 

 was much snow on the mountains yesterday evening and last night partially the cause, perhaps, of the present atmospheric condition. 

 I do not think the comparing star can exceed the 9.10 magnitude, though stated by Bessel as 8.9. 



a More steady. f Recorded 55.7s. at wire E. 



b Recorded 7.5s. at wire E. g Steady. 



c Both objects very unsteady. A Tolerably steady. 



d Very unsteady. i Good observations. 



e Recorded 9. at wire B. 



JANUARY 5, 1850. 



The night of the 5th, until the planet had passed the meridian, was cloudy.
