März 13. The Comet appeared a faint diffused nebulous body, but was seen without difflculty when 

 the sky was clear; the observations were interrupted by passing clouds and may be considered not good. 



März 28. The Comet is of considerable brightness: it is a small Condensed nebulous body, with a very 

 bright nucleus. 



April 1. The sky hazy: the Comet faint and difficult to observe. 



2. The skj' was hazy, and the bright point of the Comet was not visible. 



3. This was a flne night, and the Comet was very well seen. I do not think it is so bright as when 

 I first saw it, on March 28. 



April 4. The Comet was very bright, but there is no distinct bright spot. 

 5. The Comet was very Condensed and bright.
