You would begin to talk of scientific languages, of Esperanto, La Langue Bleue, New Latin, Volapuk, and Lord Lytton, of the philosophical language of Archbishop Whateley, Lady Welby's work upon Significs and the like. You would tell me of the remarkable precisions, the encyclopædic quality of chemical terminology, and at the word terminology I should insinuate a comment on that eminent American biologist, Professor Mark Baldwin, who has carried the language biological to such heights of expressive clearness as to be triumphantly and invincibly unreadable.
