A truly grand ducal letter, indelicate without excuse, cutting off every prospect, as he said “Au revoir” on going away, after the preconcerted shibboleth. Silence as to the costs, which are unnecessarily heavy. You and I shall cease “steering in the ocean of investigation,” as acquaintance with the party proposed does not suffice to determine him. I have a mind to answer somewhat mockingly. It may be agreeable to you, my esteemed friend, to enrich your archives with an autography of Thiers, who is now an Orleanist. Duvergier de Hauranne also came here after a pilgrimage to Eisenach. The Duchess is going to England. Preserve both letters, the bad one and that which is simply good. Yours, A. V. HT. On Saturday I expect to come to Berlin with the King. The Queen is coming on Monday. 210. CHARLES ALEXANDER, GRAND DUKE OF SAXE-WEIMAR, TO HUMBOLDT. ETTERSBURG, _June 1, 1857_. Your Excellency has probably learned already, that I have seen, repeatedly conversed with, but finally refrained from appointing ——. He interested me, I may say he pleased me, but I thought I could not recognise in him the secretary who could not only keep me informed of everything of moment in the spheres of science, art, and literature, but should attend to my correspondence, my intercourse, verbal and social, in various languages; and to appoint him at hazard I feared to venture. To retreat was, then, the only resource. I did so in order to steer further in the ocean of investigation. Whether you will continue, even in this matter, to cast upon me, as a star of good omen, the light of the goodness ever extended to me—is what I may be permitted to wish, but can hardly be permitted to hope—although we agreed that the acquaintance of the party was not to include his selection. I shall now retire into various forest solitudes of Thuringia with a number of books, among which I anticipate particular pleasure from the perusal of Barth’s itinerary. I bow in reverence before such endurance in the love of science, before such indomitable energy; how much the more must I do so before his prototype, before you? Remaining your most devoted, most grateful servant, CHARLES ALEXANDER. 211. THIERS TO HUMBOLDT. (FROM THE FRENCH.) PARIS, _May 14th, 1857_.
