the year 1782. I mention this circumstance here, as it will 
probably explain some apparent increase of brightness, that 
seems to have taken place in this star ; for although the same 
quantity of light, when it is spread over more space, must ap- 
pear less intense than it will do when it remains in a more 
confined state, it may nevertheless, by an increase of apparent 
magnitude, become entitled to be ranged upon a par with a 
brighter star. 
71 Flamsteed never observed this star. 
94 From the expressions of this catalogue, it is evident that 
the star is less now than it was 13 years ago. 
420 of Mayer's catalogue is not visible.
