ga6 "Profejfor BoJe's Aicmnl of the 



lations and aftronomical obfervations, as well as the places 

 of the heavenly bodies in aftronomical books, for the mean 

 time, as foon as the editor of the Cohmijffance Jes 7V»« fhould 

 fet us the example. Perhaps it will be poffible alfo to in-, 

 troduce this mean time into common life, in order to effedt 

 a better regulation of the going of watches, 



" Accurate and more numerous obfervations of the time of 

 the moon's culmination were next recommended, as thefe 

 might ferve in determining the difference of meridians of 

 places; alfo to infert in aftronomical almanacks the time of 

 the occultation of ftars of the fifth and fixth magnitude, be- 

 fore the firft, and after the laft quarter of the moon, in order 

 to give occafion to more frequent calculations of thefe dif- 

 ferences. In calculating the oppositions of the fuperior 

 planets, for examining the theory of their orbits, the fame 

 method muft abfolutely be followed ; and that given in La- 

 lande's Aftronomy, fecYion 4162, was here propofed. 



< f I produced a complete drawing of the fifteenth fheet, and 

 the two engraved, but not yet finilhed (beets, tab. 11 and 

 12, of my large Celeftial Atlas, and the manufcript of my 

 Complete Catalogue of the Stars, and particularly the part 

 refpecling De la Caille's Southern Stars, which have never 

 yet been numbered. Lalande took this occafion to obferve 

 that room might ftill be found on fomc of the celeftial charts 

 for new conftellations, and wiflied to fee inferted among the 

 ftars an aeroftat, as the invention of the French. I embraced 

 this opportunity, contrary to my former firm refolution of 

 introducing no new conftellations, to propofe, on the other 

 hand, that a German difcovery, made 350 years ago, viz, 

 the art cf printing, might be perpetuated in the heavens by 

 fome emblem. Both propofals were approved. The firft con- 

 ftellation will be inferted between the Goat and Southern Fifh j 

 and the other between the Ship, Unicorn, and Greater Dog. 



" Lalande was convinced, at the fame time, by ocular de- 

 monftration, of the accuracy of obfervations made with a 



Hadley'$
