260 APPENDIX II. 



Magnetic Rotations ; on Regelation ; all his more purely Chemical 

 Researches, including his discovery of Benzol. Besides these he 

 published a multitude of minor papers, most of which in the same 

 way illustrate his genius." 



Tyndall adds that no allusion is here made to his power as a 

 Lecturer. Taking him all in all, it will be conceded that Michael 

 Faraday was probably the greatest experimental Philosopher the 

 world has ever seen. The progress of future research will tend not 

 to dim or diminish, but to enhance and glorify the labours of this 

 mighty investigator. 



Speaking with regard to my own lines of research, as repre- 

 senting the Faculty of Metallurgy, I may mention that Faraday, 

 in his experiments on Alloys of Iron with other Elements, in other 

 words the production of Alloy Steel, carried out in 1821 and 1822, 

 showed that a remarkable inspiration evidently existed in his 

 mind as to the great future this line of research work presented. 

 Singular to say it is just about 100 years ago that Faraday wrote 

 several letters from the Royal Institution (in April and June, 1820). 

 to his Swiss friend De la Rive, Professor of Chemistry, Geneva, in 

 which he gave an account of some experiments on Steel made by 

 himself and Stodart. The world's great technical advances during 

 the last thirty years have been — and I say it unhesitatingly — in a 

 large measure due to the introduction of Alloy Steels such 

 as Faraday had in mind. As already mentioned, Faraday, 

 with Stodart, started these researches at the Royal Institution, 

 finally completing the experiments by sending his various 

 mixtures to be melted at the Sanderson Works in Sheffield, this Firm 

 being still in existence to-day. The specimens had to be sent by 

 coach, the work being given to a trusty assistant who had to go 

 down and see the experiments put in hand and completed. 

 Beyond the work of Mushet this particular land of Research lay 

 fallow for many years, in fact it was my own discovery and 

 invention of Manganese Steel in 1882 which showed that the 

 new world already indicated by Faraday was there ready to be 

 explored. This exploration has rapidly taken place during the 

 last thirty years, including the discovery and invention of Chromium 

 Steel, Silicon Steel, Nickel Steel, Tungsten Steel, High-speed Tool 

 Steel, Non-corroding, and many other types of Steels. 



Almost as important was the fact that Alloy Steel necessitated 

 special heat treatment, which again recjuired and called for the use of 

 scientific methods for the determination of temperatures, critical points, 

 microstructure study, improved analytical methods, media nical 

 testing, hardness determination, observation of electrical conductivity, 

 magnetic susceptibility, electrical resistance, hysteresis effects and 

 other qualities. 



In conclusion, this Society is indeed honoured in being allowed to 

 Ijear the name of so great a man as Faraday, whose work is still 

 benefiting our Empire.
