larger, exceeding the star in the bill of that constellation, as also that in the 

 bend of the lower wing, being indeed nearly equal to the star in the breast, 

 only that its light was duller and more ruddy. It was not seen in December, 

 January, and February ; for after the ] 4th of October, when it ceased to ap- 

 pear, it was sought for in vain, nor could it be seen again before the beginning 

 of March, or perhaps later. I lately measured its distance from some fixed 

 stars, and found it to be 20° 55' 20'^ from the star in the tail of Cygnus, and 

 17° 47' 50'' from that in the bend of the upper wing, also 34° 19' 40" from that 

 in the head of Serpentarius. So that it still appeared in the same place as for- 

 merly.

The new star, which Don Anthelme, a Carthusian of Dijon, lately disco- 

 vered* is one of the rarest appearances observed for some time. As this per- 

 son contemplated the heavens at night, June 20 of the last year, desirous to 

 discover that admirable star, which has appeared and disappeared twice since the 

 beginning of this century in the constellation of the Swan, viz. in its breast, he 

 perceived near the same constellation a star of the third magnitude, which he 

 had never before observed. He presently announced it to the company which 

 meets in the king's library ; and many of them observing it, agreed that there 

 was indeed about the beak of the Swan a new star of the third magnitude, not 

 to be met with in any catalogue of astronomers, although many other neigh- 

 bouring stars, that are much smaller, be exactly marked by them. It was si- 

 tuate as appears in the fig. 2, pi. 14. 



Supposing the obliquity of the ecliptic to be 234- degrees, the longitude of 

 this star, according to the observation of Mr. Picard, was 1° 55' of Aquarius; 

 the right ascension 293° 33'; the north latitude 47° 28'; and the declination 

 26° 33'; it came to the meridian after the star in the beak of the Swan l6^ 44'; 

 and before the bright star of the Eagle 0™ 27^ It was distant from the great 

 star of the constellation Lyra 18° 39' 40''; from the beak of the Swan 3° 47' 30"; 

 and from the tail of the Swan 20° 54' 30'. 



It is further remarkable, that in the beginning of Julyj- this star was observed 

 to decrease. In the night of July 3, it appeared yet of the third magnitude, 

 but its light was sensibly fainter. In the night of the 1 1th of the same month
