had rather paffed its leaft brightnels, beuig nearly equal to ; An- 

 tinoi, and when it was a little, but undoubtedly, brjghtti- 

 than jQ Aquiliie. Though it does not appear, as I have already 

 laid, that any of the other phafes can be fettled with equal 

 precifion, different comparifons neverthelefs may prove fatii- 

 fa6lory towards corroborating the above ; I have therefore alfo 

 deduced its period from the befl and mofc diftant obfervations, 

 inade when at its leaft brightnefs ; they are thus : 7 days 

 o hours and 7 days 5 hours. Thefe refults I reject, and retain 

 the n:iean given by the hrfl fet, with w4:iich we may proceed on 

 to gain a much greater exa^tnefs ; let one period be fubtra^led 

 from the obfervation of July 27th, 1783, and it will appear, 

 that fi Antinoi had varied in brightnefs during the following 

 four days, though at that time it did not ftrike me. 



July 17th, decidedly brighter than /3 Aquilae* 



— I 8th, not obferved. 



1783, "j — 19th, rather brighter than /3 Aquiiie^ 



— 20th (anfwering to the 27th) equal or rather 

 lefs than /3 Aquikt* 



As it is therefore evident, that on July 19th and 27th, 1783, 

 'i] Antinoi was decreajing m brightnefs, 1 (hall compare thole
