Cuvier was such a man. Alone, and unapproached in his own spheres of knowledge, his "Report on the Progress of the Natural Sciences" is only an index to the wide range of his intellect. In one point, however, we must own that he seems slow of apprehension or limited by preconceived opinions,--in his reception of the homologies pointed out by Oken and the Physiophilosophical observers. In the same range of intellects we should reckon Linnaeus and Humboldt, and should have reckoned Goethe, had he given himself to science. We do not assume to say where in the category of fully equipped intelligences Mr. Agassiz belongs. But if the union of the most extraordinary observing powers with an almost poetic perception of analogies, with a wide compass of thought, the classifying instinct and habit, large knowledge of books, and personal intimacy with the leaders in various departments of knowledge, and with this the upward-looking aspect of mind and heart, which is the crowning gift of all,--if the union of these qualities can give to the man of science a claim to the nobler name of wisdom, it is not flattery, but justice, to award this distinction to Mr. Agassiz. To him, then, we listen, when, after having sounded every note in the wide gamut of Nature, after reading the story of life as it stands written in the long series of records reaching from Cambrian fossils to ovarian germs, after tracing the divine principle of order from the starlike flower at his feet to the flower-like circle of planets which spreads its fiery corolla, in obedience to the same simple law that disposes the leaves of the growing plant,--as our eminent mathematician tells us,--he relates in simple and reverential accents the highest truths he has learned in traversing God's mighty universe. For him, and such as him,--for us, too, if we read wisely,--the toiling slaves of science, often working with little consciousness of the full proportions of the edifice they are helping to construct, have spent their busy lives. All knowledge asserts its true dignity when once brought into relation with the grand end of knowledge,--a wider and deeper view of the significance of conscious and unconscious created being, and the character of its Creator.
