HISTORICAL OUTLINE 15 



[)hysicist. The facts set out in Chapter 3 show clearly the rapid advance that 

 has followed the incursion of the biochemist into the bacteriological domain. 

 Those described in Chapter 6 show the organic chemist and the biochemist initiating 

 a remarkable extension of chemotherapy in relation to bacteria, and the out- 

 standing success of synthetic sulphonamide compounds, and of the natural mould- 

 product, penicillin ; and those described in Chapter 7 show the organic and physical 

 chemist inaugurating a new era in immunology. The remarkable increase within 

 quite recent years of our knowledge of the filtrable viruses (see Chapters 41 and 

 85-89) has resulted in large part from improved methods of filtration, optical 

 examination and high-speed centrifugation. It is not a rash prophecy that the 

 years ahead of us will be the eighteen-eighties over again.
