with this understanding they were ready, to help him generously. He compared their liberality with that of kings and princes, when these patronized science, with a recognition of the superior plebeian generosity. It was on the veranda of his summer house at Nahant, while he lay in the hammock, talking of this, that I heard him refer also to the offer which Napoleon III. had made him, inviting him upon certain splendid conditions to come to Paris after he had established himself in Cambridge. He said that he had not come to America without going over every such possibility in his own mind, and deciding beforehand against it. He was a republican, by nationality and by preference, and was entirely satisfied with his position and environment in New England.

Outside of his scientific circle in Cambridge he was more friends with Longfellow than with any one else, I believe, and Longfellow told me how, after the doctors had condemned Agassiz to inaction, on account of his failing health he had broken down in his friend's study, and wept like an 'Europaer', and lamented, "I shall never finish my work!" Some papers which he had begun to write for the Magazine, in contravention of the Darwinian theory, or part of it, which it is known Agassiz did not accept, remained part of the work which he never finished. After his death, I wished Professor Jeffries Wyman to write of him in the Atlantic, but he excused himself on account of his many labors, and then he voluntarily spoke of Agassiz's methods, which he agreed with rather than his theories, being himself thoroughly Darwinian. I think he said Agassiz was the first to imagine establishing a fact not from a single example, but from examples indefinitely repeated. If it was a question of something about robins for instance, he would have a hundred robins examined before he would receive an appearance as a fact.

Of course no preconception or prepossession of his own was suffered to bar his way to the final truth he was seeking, and he joyously renounced even a conclusion if he found it mistaken. I do not know whether Mrs. Agassiz has put into her interesting life of him, a delightful story which she told me about him. He came to her beaming one day, and demanded, "You know I have always held such and such an opinion about a certain group of fossil fishes?" "Yes, yes!" "Well, I have just been reading ------'s new book, and he has shown me that there isn't the least truth in my theory"; and he burst into a laugh of unalloyed pleasure in relinquishing his error.

I could touch science at Cambridge only on its literary and social side, of course, and my meetings with Agassiz were not many. I recall a dinner at his house to Mr. Bret Harte, when the poet came on from California, and Agassiz approached him over the coffee through their mutual scientific interest in the last meeting of the geological "Society upon the Stanislow." He quoted to the author some passages from the poem recording the final proceedings of this body, which had particularly pleased him, and I think Mr. Harte was as much amused at finding himself thus in touch with the savant, as Agassiz could ever have been with that delicious poem.

Agassiz lived at one end of Quincy Street, and James almost at the other end, with an interval between them which but poorly typified their difference of temperament. The one was all philosophical and the other all scientific, and yet towards the close of his life, Agassiz may be said to have led that movement towards the new position of science in matters of mystery which is now characteristic of it. He was ancestrally of the Swiss "Brahminical caste," as so many of his friends in Cambridge were of the Brahminical caste of New England; and perhaps it was the line of ancestral pasteurs which at last drew him back, or on, to the affirmation of an unformulated faith of his own. At any rate, before
