A considerable change seems to have taken place in the 

 position of these stars since 1783, in which year the measures 

 were : Position 64° 12' sf; Distance 44''.93. The difference, 

 6° 1 5', is much more than could be fairly attributable to error 

 of observation in a star of the 5th class, except under very 

 difficult circumstances. (H.)
