Observed with 413 ; but the measures are very difficult, because the distant blue 

 star C does not bear so high a magnifying power ; indeed it is so very indistinct* 

 that it is seen only with great attention.

Observed when 10 minutes west of the meridian with 413 ; the measures are dif-

Observed when 10 minutes west of the meridian with 327, with which the discs 

 of the two stars A and B seemed in contact : variable refraction prevented mc 

 using a higher power : the stars were at times well defined.

Observed by twilight with 181, which sufficiently separated the two discs of the 

 close pair A B ; stars 20 minutes east of the meridian at the time the measures 

 were taken.
