The man, on the other hand, who is specially gifted with the power of scientific discovery will not be affected by such temporary fellowships. He will enter on the career of discovery with or without such inducements. What such a man (and he is the only sort of man who matters) really requires, and should find open to him, is an assured career. This must take the form in the first place of a smaller post as assistant to a great discoverer, tenable for twenty years if need be, and subsequently a life post, with laboratory and assistants, when he has proved his possession of the discoverer's quality. Hence it is that what the benevolent millionaire who wishes to promote scientific discovery should do is to provide life posts, "professorships" or "directorships," for the really great discoverers, who exist often in cramped conditions. They should be of the value of £1500 to £3000 a year--not too large a stipend in view of the incomes earned by successful professional men and assigned by Government to judges, bishops, colonial governors, senior civil servants, and politicians--with two or three assistantships of £150 to £500 a year attached, to be filled up by nominations made by the professor himself as vacancies occur. A sum of £7500 a year, that which Mr. Otto Beit has so generously given, would pay for one professor, with three assistants, attendants, and interest on building and maintenance fund. Of course, if such a sum were offered to an existing institution where buildings and other conveniences are already provided, two research professors and their assistants could be paid for where one only would be possible if building and service had to be provided. There are buildings and laboratories in London and elsewhere provided by beneficent founders without stipends for directors and assistants, and there are already a good many young graduates drawing terminable inadequate stipends in succession to one another from great foundations. The difficulty is to bring about the combination of adequate funds for the chief and for the graduated minor posts, and for a well-equipped laboratory. When that is done, as it sometimes, though rarely, is, the only further difficulty is how to choose a real man, an inspired, inspiring discoverer. There is only one way.
