INFERIOR CONJUNCTION OF VENUS, 1852, 



Remarks. 



Sharp images all the morning, but their cirri prevented the star from being seen under sufficient illumination for its observation with satisfaction. 

 At 3h. 23m. it was found that the hour circle clamp was not fast, and, therefore, the differences of R. A. marked a are wrong, and are omitted in the 

 results.
