^weather was not very favourable.

Dec. 21. At oh. much lefs than 7. and eonfiderably 
brighter than f Lyras; not quite of the fourth magnitude. 
At 18 h. a little brighter than f and jc, and brighter than I 
Lyras ; between the fourth and fifth magnitude. 
Dec. 28. At 6 h. lefs than y and brighter than 9 Herculis-: 
between the "third and fourth magnitude. At 8 h. nearly equal 
to 9 Herculis ; between the fourth and third magnitude.

magnitude,, 
Jan. 6. At 5I h. between y Lyras and 9 Herculis, but rather 
nearer 7 . At 8| h. it feemed a little brighter than y. 
From the above feries of obfervations I have deduced all the 
conclufions relative to the eight points of the variation, as they 
are Hated in the beginning of this paper. However, as at find it 
•may not clearly appear, that the ftar has a more confiderablc 
diminution in the third point than in the feventh, it will not 
be improper to add a few words relating to that circumifance : 
for proof of it, therefore, I refer to an attentive comparifon of 
the obfervations of Sept. 10. Sept. 23. Oft. 5 and 6. Oft. 
18 and 19. See . correfponding to the third point of the varia- 
tion with thofe of Sept. 29 and 30. Oft. 25. Nov. 7 and 
19, &c. correfponding to the feventh point of the varia- 
tion. It may be objefted, that in fome of the obfervations of 
the feventh point, the ftar might have become Hill more di- 
minifhed in the intermediate hours ; . hut this is not probable,
