I. "Notes on the Spectrum of the Aurora." By J. NORMAN 

 Lockyer, F.R.S. Received January 9, 1888. 



I exhibited to the Society on November 17, 1887, a tabular statement 

 showing the bright lines seen in the spectra of various celestial bodies, 

 and I also gave those recorded in the spectrum of the Aurora showing 

 many remarkable coincidences. 



I now find that the connexion is closest between the auroral 

 spectrum and that of stars 3a, and in anticipation of a subsequent 

 communication of details I send on the accompanying table, showing 

 the origin of Duner's bands, so far as I have at present made them 

 out, and their connexion with the spectrum in question. 



The individual observations which I have used in the table are 

 those collected by Mr. Capron and Mr. Backhouse (' Nature,' vol. 7, 

 pages 182, 463).
