EESULTS OF OBSERVATIONS OF COMETS I. AND II. 



by a portion of the observatory buildings, and the positions had 

 to be determined with the small instrument. The moon too, 

 increased nightly in brilliancy and the comet became quite invisible. 

 On the withdrawal of the full moon the comet was picked up 

 again with the 8 inch telescope and observed till August 1st, 

 when, owing to its increasing distance from the sun and earth it 

 was little more than a faint whiteness about 2' in diameter on the 

 blue of the heavens. All the observations in this paper were 

 made with a square bar-micrometer adapted to both equatorials. 

 There being no definite point for observation, all that could be 

 done was to observe the bisection of the nebulous mass at the 

 edges of the micrometer-bars. In the reduction of the comparisons 

 corrections were carefully applied for small errors in the form of 

 the micrometer.
