some other compound with a much longer name but with no higher 

 destiny than to fill a place in Beilstein. 



So also in physical chemistry. A careful, painstaking investigation 

 of some of our already established industrial processes with a view to 

 determining the maximum yield at the minimum cost is of the greatest 

 educational value. In other words, a problem for research may have a 

 distinctly practical bearing without being any the less a study in pure 

 science, or without having thereby an inferior educational value. 



In other problems we have noted, the solution largely depends upon 

 the process, not the reaction. This demands the chemical engineer, 

 a man who combines a broad knowledge of general chemistry with the 

 essentials of mechanical engineering. He must be well schooled in 

 the economics of chemistry; have a knowledge of the strength and 

 chemical resistance of materials; be able to design and operate the 

 mechanical means for carrying out on a commercial scale the reactions 

 discovered, and duplicating the conditions already determined. 



With men whose foundations are thus broadly and deeply laid, 

 anxious to enter the industrial arena, and with a generous apprecia- 

 tion of the scientific man on the part of the manufacturer, coupled 

 with a willingness to grant him an adequate return on the money 

 invested in such an education, the problems in technical chemistry of 

 the present must rapidly become the achievements of the past.
