On the Spectra of some of the Fixed Stars. 



which we know to be indispensable to the existence of living or- 

 ganisms such as those with which we are acquainted. On the 

 whole we believe that the foregoing spectrum observations on 

 the stars contribute something towards an experimental basis on 

 which a conclusion, hitherto but a pure speculation, may rest, 

 viz. that at least the brighter stars are, like our sun, upholding 

 and energizing centres of systems of worlds adapted to be the 

 abode of living beings.
