IX. — Corrigenda in YarnalPs Catalogue, second edition (1878). 



NdTE. — This catali>i;vio in greater part is dcrivi'd from observations with tlie Transit iiistrnniont for tlio riglit 

 ascensions and vritli the Mnral circle I'cirthe declinations. Very often, however, the ])recaution was neglected to read 

 the second co-ordinate with snfficient apjiroxiniation far identifying the star beyond ijiiestion. Therefore in composing 

 the catalogue not seldom wrong combinations of right ascension and declination were niado, giving rise to spurious 

 stars, which of course are found among the many anonymous of which the catalogue abounds. To sift these, a com- 

 parison with other catalogues was made by me. Professor MiUoserkli recently has published (Attuali della iletcorologia 

 Hallana, Parte III, 1884) a complete investigation of all the anonymous in Yarnall's Catalogue Ihat come within the 

 limits of the DKrclimiislcrKiifj. For tlu'se, therefore, I have suppressed my notes, except where I differ from my distin- 

 guished friend in the conclusions arrived at, or wheie ii more detailed elucidation, by going back to the ll'asliiuiitoii 

 Obserialioiis, seemed necessary for contirniing some of his veiy hajipy conjectures. Below I apjieud a supplemental 

 list of YarnalTs anonym(Dis, the positions of which I found secured liy other catalogues.
