lege not only invaluable discoveries himself, but trained chemists like himself. His intellectual tradition or heritage remains still with us, although he himself was allowed to leave us and to accept a more honoured and honourable post in Bonn and later in Berlin. Similarly such men as Johannes Müller, of Berlin, the biologist, and the Cambridge successive leaders in physics—Stokes, Kelvin, Clark Maxwell, Raleigh, and J. J. Thomson—exhibit (as many other instances do) the generative activity of a really great investigator on those who work with him. Therefore in the first instance the State must offer whatever salary is necessary (say, in each case £5,000 a year—the salary of those numerous and admirable officials, H. M. judges) and whatever laboratory, apparatus, and assistants (say to the equivalent in each case of £10,000 a year) in order to secure the greatest discoverer in each line, as head of the corresponding "institute." In such a matter the State officials responsible must obtain the advice of the leading makers of new knowledge of all parts of the world and form a judgment. Once we have got our great heads or directors of institutes, the scheme will work successfully. It will be the duty of the director of each institute to receive a certain number of selected "workers" into his laboratory (or museum, library, or workshop) and to associate them with himself in investigation. These workers must be selected from among those who volunteer for the career. I assume that in the new Great
