But that which is further remarkable,, is, - that in the beginning of 
^ . ffily* this StSiT was obferved to decreafe. In the 
night of pdy id, it appear'dyetofthe Third 
iude^ but her Light was fenfibly fainter. In the night 
of the wthoi the fame month, flie fcarce appeared of the Fourth mag- 
nittide.. In the night of Jt^gnfi ioth,{hz was but of the Fifth, And Ihe 
hath ever fince decreased ftili/o that at Uft ftac became fo fraall that Gie 
was feen no more. 
Andfofhehathremainedfor fix months without file wing her felf, 
and we could not difcover her again till the night of March lyth 
laft, when Dd^t Anthelme fpied her in the very fame place, where 
file was the year before, and found, that flie was of the Fonrth 
rndgnhnde^ 
The Affei;nbly that meets in the Kings Library, having notice there- 
of, fcveral of them did obferve this Star in the night of the zd of 
u4prilh{k, finding her in the felf fame place where they had feen her 
the precedent year. The 3^ of the fame month M. CaJJlni (ound her 
greater than the two Stars of the Third magnitude that are below in the 
Conilellationof Z^r^^, but a little fmaller than that in the Beak of 
Cygnus, 
The \th of the fame month, fiie appearM to him almoft as 
great and . much more radiant than that of the Beak of the 
The pr^ af the fame, he found her a little diminifli*c ^ and almoft e» 
qual to tfcgreateft -of the two Scars that, are below in Lyra. 
The izth^ fhe was equal to the lead of thefe two Stars. 
The 1 5?^,he perceived that (he en(;reafed,a-nd he found her equal ,the 
fecond time5to the greateft of thefe two Star^. 
From the idr^ unto the z'^thy flie appeared of different magnitudes, 
being fometiraes equal to the biggeft of thefe two Scars, fometimes e- 
qual to the leaft, and now and then between bo fli. 
But the z^th and 28r^,flie was become as big as the Star in the Swans 
heak^: The 3 0/^, flie appeared a little clearer, And the. firft fix days in 
^^j, flie was greater. ' ' . ' : . 
The J %thof May fl^e was feen fmaller than the fame Star. - The 'i6tfs^.. 
flie was in bignefs between the two Stars that are below in Lyra \ Arid

Thus this Star hath been twice in her greateft fplendour, fit'ft on the

we read not to have ever happen'd to any other Star. 
As far as can be judged from the few Qbfervations made of 
this Star, *tis likely flie is returning about 7"^« months unto the fame 
appearance- whereas that in the ^;^^/^*^A^f*r)^ make th its revolution

as yet no certain knowledge of the period of her revolution v
