338 SECTIONAL TRANSACTIONS.— B. 



The success of the dyestuffs industry showed in a very clear way the 

 importance of organic chemistry as a tool in a modern world. 



The practice of medicine has been enriched by this same tool : the whole 

 range of local anaesthetics, many of the sleep-inducing compounds, and the 

 sole remedy for sleeping sickness, are the results of this molecular archi- 

 tecture. Modern photography, particularly in the developers and sensi- 

 tisers, is the gift of this branch of chemistry. The ubiquity of the motor 

 car, in its fuel and its tyres, is a derived benefit from organic chemistry. 

 It has given the textile industry two new fibres. Recently in its work on 

 detergents and vitamins it still carries the torch. Always does it seem to 

 have caused benign revolutions ; it appears still to be capable of causing 

 others. 



Sir Henry Dale, C.B.E., F.R.S. — The training of chemists for work 

 in the fields of biochemistry and medicine (12.0). 



In recent years Chemistry has newly and rapidly invaded the fields of 

 functional Biology and the sciences related to Medicine. Even in the study 

 of the complex phenomena of immunity, the results of recent years have 

 shown a beginning of exact description in terms of organic and physical 

 chemistry. Up till about 1920 only some four hormones were known 

 as separable entities, and of these only two had been chemically defined. 

 In the last few years a whole series has been chemically isolated, and several 

 have been made artificially by synthesis. Of the vitamins, known a few 

 years ago only by the effects of their absence, four or five have been chemically 

 identified, and at least three have been artificially prepared. Sex hormones, 

 one vitamin, carcinogenic substances, and heart tonics have all been 

 chemically related to the typically inert sterols. New synthetic compounds 

 of chemotherapeutic value give promise of control over some of the most 

 deadly infections of man, especially in the Tropics. The whole orientation 

 of therapeutics is being shifted from the effects to the causes of disease. 

 It is suggested that this new and increasing domination of biological and 

 medical research, by chemical methods and ideas, represents the greatest 

 of all the services of chemistry to the community. It calls for chemists 

 of the highest ability, so trained that they can fully co-operate and share 

 the planning of future progress with those primarily trained in biology and 

 the medical sciences.
