company with a few others, mostly known to us, we are provided with a good and neatly served meal. After dinner we go to Dr. Waltl, with whom we study chemistry, using Gmelin's text-book, and are shown the most important experiments. Next week we are to begin entomology with Dr. Perty, from three to four, three times a week. From one to two o'clock on Saturday we have a lesson in experimental physiology, plainly speaking, in animal dissection, from Dr. Oesterreicher, a young Docent, who has written on the circulation of the blood. As Agassiz dissects a great many animals, especially fishes, at the house, we are making rapid progress in comparative anatomy. At four o'clock we go usually once a week to hear Oken on "Natur-philosophie" (a course we attended last term also), but by that means we secure a good seat for Schelling's lecture immediately after. A man can hardly hear twice in his life a course of lectures so powerful as those Schelling is now giving on the philosophy of revelation. This will sound strangely to you, because, till now, men have not believed that revelation could be a subject for philosophical treatment; to some it has seemed too sacred; to others too irrational. . .This lecture brings us to six o'clock, when the public courses are at an end: we go home, and now begin the private lectures. Sometimes Agassiz tries to beat French rules and constructions into our brains, or we have a lesson in anatomy, or I read general natural history aloud to William Schimper. By and by I shall review the natural history of grasses and ferns, two families of which I made a special study last summer. Twice a week Karl Schimper lectures to us on the morphology of plants; a very interesting course on a subject but little known. He has twelve listeners. Agassiz is also to give us lectures occasionally on Sundays upon the natural history of fishes. You see there is enough to do. . . Somewhat before this, early in 1828, Agassiz had made the acquaintance of Mr. Joseph Dinkel, an artist. A day spent together in the country, in order that Mr. Dinkel might draw a brilliantly colored trout from life, under the immediate direction of the young naturalist, led to a relation which continued uninterruptedly for many years. Mr. Dinkel afterward accompanied Agassiz, as his artist, on repeated journeys, being constantly employed in making illustrations for the "Poissons Fossiles" and the "Poissons d'Eau Douce," as well as for his monographs and smaller papers. The two larger works, the latter of which remained unfinished, were even now in embryo. Not only was Mr. Dinkel at work upon the plates for the Fresh-Water Fishes, but Mr. J.C. Weber, who was then engaged in making, under Agassiz's direction, the illustrations for the Spix Fishes, was also giving his spare hours to the same objects. Mr. Dinkel says of Agassiz's student life at this time:--* (* Extract from notes written out in English by Mr. Dinkel after the death of Agassiz and sent to me. The English, though a little foreign, is so expressive that it would lose by any attempt to change it, and the writer will excuse me for inserting his vivid sketch just as it stands.--E.C.A.)
