of a new Variable Star, i6i 



Dec. 19. At 9 h. I believe it was brighter than y, but the 

 weather was not very favourable. 



At 19 h. little lefs than y. 



Dec. 20. At 5|h. lefs than 7 I.yrs^, and brighter than 

 9 and P Herculls. At 6f h. nearly equal, thou?-h rather lefs 

 than y Lyric. 



Dec. 21. At 8 h. much lefs than y, and confiderably 

 brighter than ^Lyras; not quite of tJic fourth magnitude. 



At i8h. a little brighter than f and z, and brighter than 

 Lyras; between the fourth and fifth magnitude. 



Dec. 28. At 6h. lefs than 7/ and brighter than Herculls ; 

 between the third and fourth magnitude. At 8 h. nearly equai 

 to 9 Herculls ; between the fourth and third magnitude. 



1785, Jan. 5. At 5^h. about equal to Herculls; fourrh. 

 magnltudeo 



Jan. 6. At 5 1 h. between y Lyrae and d Herculls, but rather 

 Bearer y. At 8| h. it feemed a little brighter than y. 



From the above ferles of obfervations I have deduced all t'no 

 •conclufions relative to the eight points of the variation, as they 

 are ftated in the 'beginning of this paper. However, as at firfl ft 

 may not clearly appear, that the (hir has a more connderable 

 diminution in the third point than in the feventh, it will not 

 be improper to add a few words relating to that circumfrance : 

 for proof of it, therefore, I refer to an attentive compariion of 

 the obfervations of Sept.. 10. Sept. 23. 0£l. 5 and 6. 0£l', 

 18 and 19. &c. correfponding to the third point of the varia- 

 tion with thofe of Sept, 29 and 30. 0£l. 25, Nov. 7 and 

 19, &c. correfponding to the feventh point of -the varia- 

 tion. It may be objected, that in fome of the obfervations of 

 the feventh point, the ilar might have become ftili more di- 

 •mlnlfhed in the intermediate hours; but tiiis is, not probable.
