had rather pnflecl its lead brightnefs, being nearly equal to i An- 

 tlnoi, and when it was a little, but undoubtedly, brighter 

 than jQ Aquilas. I'hough it does not appear, as I have already 

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

 preclfion, different comparifons neverthelefs may prove fatif- 

 fa61:ory towards corroborating t^e above ; I have therefore alfo 

 deduced its period from the beft and moft diftant obfervations^ 

 made when at its leafl brightnefs; they are thus: 7 days 

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

 the mean given by the flrfl: fet, with which we may proceed on 

 to gain a much greater exaulnefs ; let one period be lubtra^ted 

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

 that 17 Antinoi had varied in brightnefs during the following 

 four daySy though at that time it did not ftrike me. 



July 17th, decidedly brighter than /3 Aquilae. 



— 1 8th, not obferved. 



1783, "J — 19th, rather brighter than ,G Aquilas. 



— 20th (anfwering to the 2 7tii) equal or rather 

 lefs than jG A qui lie. 



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

 7] Antinoi was decreafing in brightnefs, I fhall compare thole 

 days obfervations to correfponding ones made in 1784,
