" Flame Spectra observed at Swedish Bessemer Works." By 

 C. J. Lundstrom, Ortofta, Sweden. Communicated by 

 Professor W. N. Hartley, F.R.S. Received April 1, — 

 Read June 20 —Revised October 18, 1895. 



Introduction. 



As no examinations of the Bessemer flame from Swedish steel works 

 had been previously made, I resolved, some years ago, to devote 

 attention to this subject, in order to see to what extent the Bessemer 

 spectrum in Sweden differs from those of other countries, and partly 

 to ascertain whether the spectroscope might be of any practical use in 

 examining the Bessemer " blow." 



My observations were made at the following Bessemer works : — 

 Nykroppa, Hagfors, Langshyttan, and Ulfshyttan and partly also at 

 Domnarfvet. 



Embracing the present opportunity, I beg to be allowed to express 

 my thanks to all the managers and engineers of these works for the 

 courtesy I have met with. Especially I am gratefully indebted to 

 Mr. Martin Nisser, the manager of the Klosters Iron Works, for the 

 interest he has shown in procuring a spectroscope adapted to the 

 requirements of this investigation, which he placed at my disposal.
