double liars, which I difcovered this fummer; at leafl, I 
prefume, they have not been obferved before, hecaufe I do not 
find them inferted in Dr. Bradley’s catalogue, publilhed in 
the Nautical Almanac 1773, or in the Connoijfance des Terns, 
no more than in other catalogues in my poffeffion. y Delphini, 
indeed, is in M. de la caille’s catalogue ; but not as a dou-

quadrant it appears only as a {ingle ftar. Thefe Bars were ob- 
ferved by me in a three-feet achromatic telefcope of a tranfit 
inflrument, with an objedt-glafs near two inches diameter.
