Science represents the second great interest which has shown an active concern in the settlement of this question.
To follow up any line of scientific research is already a sufficiently gigantic work, on account of the absence of proper bibliographical organization; it becomes almost overwhelming now that the search has to extend over at least half a dozen languages, and still leaves the searcher a stranger to the important investigations which are appearing in Russian and in Japanese, and will before long appear in other languages.
Sir Michael Foster once drew a humorous picture of the woes of the physiologist owing to these causes. In other fields—especially in the numerous branches of anthropological research, as I can myself bear witness—the worker is even worse off than the physiologist.
Just now science is concentrating its energies on the organization of bibliography, but much attention has been given to this question of an international language from time to time, and it is likely before long to come pressingly to the front.
The medical profession is also practically concerned in this question; hitherto it has, indeed, taken a more lively interest in the effort to secure an international language than has pure science. It is of the first importance that new discoveries and methods in medicine and hygiene should be rendered immediately accessible; while the now enormously extended domain of medicine is full of great questions which can only be solved by international co-operation on an international basis.
