1 64 Mr, Goodricke's Ohfervattons of a new Variable Star, 



and /S of between the fourth and third. I have, however^ 

 fome doubts whether the variation of this ftar does not entirely 

 ceafe or become lefs vihble in certain years. Thefe doubts ari(e 

 from fome obfervations of Cassini in Phil. Tranf. N"" y^^ 

 p. 2198. where I find that in obferving the new il:ar, which, 

 then appeared near the beak of the Swan, he compared it very 

 fr,equently for upwards of a month to /S and y Lyr^, yet 

 without perceiving, or even fufpe6i:ing, that /G was variable^ 

 though it was eafy for him to have perceived it, if th^ varia* 

 tion had then been even lefs than it is now.- 



I am, &c, 



JOHN GOODRICKE*
