This is the last portrait painted from life of Humboldt, and as it is the last, so it is the best. Whether we regard its resemblance to the great original, or its artistic execution, all agree that it has never been equalled. With this picture, Humboldt was so much pleased, that he induced the painter, Professor Schrader, to exhibit it in Humboldt's own room, and it was standing opposite his bed, when he died. He breathed out his spirit, while looking at the picture, whose back-ground doubtless suggested to him his early labors and triumphs. The following letter, translated from the German, will prove interesting to all: "How should I not be moved, my dear Mr. Aufermann, by all the kindness and honor shown to me in the United States of America! My portrait, by our great historical painter, Professor Schrader, combines in the happiest manner great physiognomical truth with depth of feeling, and the most laborious technicality. Considering the increasing good will bestowed on me in your country, I hope that the work of a dear friend will find favor in your exhibition. . . .
