INFERIOR CONJUNCTION OF VENUS, 1850-51, 



Remarks. 



Venus appears like an imag in a basin of agitated mercury, and is wholly impossible to measure with any degree of accuracy under a power of 

 150. Efforts were made with lower powers from 22/i. 6m. until 23A.. 10m. sid. time; but it was still found impracticable, a cold SE wind (from the 

 Andes) evidently producing rapid changes in the refraction.
