liacl rather palled its lead: brightnefs, being nearly equal to i An- 
tinoi, and when it was a little, but undoubtedly, brighter 
than /3 Aquilae. Though it does not appear, as I have already 
faid, that any of the other phafes can be fettled with equal 
precilion, different comparifons neverthelefs may prove fatif- 
fadory towards corroborating the above ; I have therefore alfo 
deduced its period from the bed and mod didant obfervations, 
made when at its lead brightnefs ; they are thus: 7 days^ 
0 hours and 7 days 5 hours. Thefe refults 1 rejed, and retain, 
the mean given by the fird fet,. with which we may proceed on 
to gain a much greater exadnefs ; let one period be fubtraded: 
from the obfervation of July 27th,. 1785, and it will appear,, 
that y\ Antinoi had varied in brightnefs during the following; 
four days, though: at that time it did hot d'rike me. 
S July 17th, decidedly brighter than jG.Aquilae;. 
— 1 8th, not obferved. 
*703, > — 1.9th, rather brighter than /3 Aquilae. 
I — 2.0th (anfwering to the 27th) equal or rather 
t lefs than (3 Aquilae.* 
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.
