Not difficult. 
Observed when 10 minutes west oF the meridian. Evening very favourable ; 
stars remarkably steady, and well defined. The results highly satisfactory. 
Examined the large star with 413 and 512, but found it perfectly round; hence the 
discordances do not arise from any elongation of it, under the ordinary observing 
powers employed.
