POSTSCRIPT TO THE CATALOGUE OF DOUBLE STARS. 
SINCE my having delivered my paper on the Parallax of 
the Fixed Stars, in which I refer to the above Catalogue of 
Double Stars, I have received,, by the favour of our Prelident 
Sir Joseph banks, the fourth volume of the A<fta Academia^ 
Theodoro Palatinae, which contains a mod; excellent Memoir of 
Mr. mayer’s, “ De novis in Coelo fidereo Phaenomenis 
wherein: I : fee that the idea of afcertaining the proper motion 
of the fbirs by means of fmall ftars that are fttuated at no great 
diftance from large ones* has induced that gentleman before 
me to look out for fuch fmall. ftars. In the courfe of that un- 
dertaking he has difcovered a good many double liars, of which 
he has given us a pretty large lift, fome of them the lame with 
thofe in my catalogue. My view being the annual parallax 
required ftars much nearer than thofe that would do for Mr. 
mayer’s
