of a new Varlalk Star, 1 6 r 



Dec. 19. At 9 h. I believe It was brighter than 7, but the 

 weather was not very favourable. 



At 19 h. little lefs than y. 



Dec. 20. At 55 h. lefs than y Ivvra,', and brighter tliau 

 5 and I Herculls. At 6.| h. nearly equal, though rather lels 

 than y Lyrct. 



Dec. 21. At 8 h. much lefs than 7, and confiderably 

 brighter than ^Lyrae ; not quite of the fourth magnitude. 



At 18 h. a little brighter than ^ and jc, and brighter than J 

 Lyra^; between the fourth and fifth magnitude. 



Dec. 28. At 6h. lefs than 7 and brighter than 5 Herculls ; 

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

 to Q Herculls ; between the fourth and third magnitude. 



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

 magnitude* 



Jan. 6. At 5I h. bettveen y Lyrae and 5 Herculls, but rather 

 nearer y. At 8| h. It feemed a little brighter than y. 



From the above ferles of obfervations I have deduced all the 

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

 are flated in the beginnmg of this paper. However, as at firil It 

 •may not clearly appear, that the ftar has a more confiderable 

 diminution in the third point than In the feventh. It will not 

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

 for proof of it, therefore, I refer to an attentive coniparlfon cA 

 the obfervations of Sept. 10. Sept. 23. Oct. 5- and 6. Ode, 

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

 tion with thofe of Sept. 29 and 30. Odi. 25, Nov. 7 and 

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

 tlon. It may be objefted, that in fome of the obfervations of 

 the feventh point, the ftar might have become flMl.more di- 

 minlfhed in the Intermediate hours ; but this is not probable^
