"ON THE REGENERATIVE GAS FURNACE AS 

 APPLIED TO THE MANUFACTURE OF CAST STEEL." 



[A Lecture delivered before Hit Fellows of the Cliemical Society, May 7th, 1868.] 



By C. W. SIEMENS,* F.R.S., Mem. Inst. C.E. 



IN responding to your call to deliver a lecture to your Society, 

 on a subject of applied chemistry, I feel that I have undertaken 

 a very responsible task, a responsibility which is only balanced 

 by the honorary distinction conferred by your call. 



It is a hopeful sign of the advancement of science that your 

 Society puts itself into intellectual communication with en- 

 gineers and others, whose mission it is to apply and practise 

 that pure science cultivated within your body. It would be pre- 

 sumptuous on my part to reason with you upon a purely chemical 

 subject, for although many years ago I had the advantage of re- 

 ceiving instruction f romWohler and Himly, I can in no way lay claim 

 to be a chemist of the present day. Yet I can safely affirm that 

 of all the instructions I received in early life, there is none that 

 has been a more useful guide to me in my professional pursuits. 



The subject to which I wish to call your attention this evening 

 is one that has occupied my mind for many years, and which I hope 

 may engage your interest, involving as it does the generation of 

 intense heat by means essentially differing from those in general 

 use, and the application of that heat to the production of cast steel 

 in large masses, and directly from the ore or scrap metal.
