A far more stimulating intellectual life than that of Heidelberg awaited our students at Munich. Among their professors were some of the most original men of the day,--men whose influence was felt all over Europe. Dollinger lectured on comparative anatomy and kindred subjects; Martius and Zuccarini on botany. Martius gave, besides, his so-called "Reise-Colleg," in which he instructed the students how to observe while on their travels. Schelling taught philosophy, the titles of his courses in the first term being, "Introduction to Philosophy" and "The Ages of the World"; in the second, "The Philosophy of Mythology" and "The Philosophy of Revelation." Schelling made a strong impression upon the friends. His manner was as persuasive as his style was clear, and his mode of developing his subject led his hearers along with a subtle power which did not permit fatigue. Oken lectured on general natural history, physiology, and zoology, including his famous views on the philosophy of nature (Natur-philosophie). His lectures gave occasion for much scientific discussion, the more so as he brought very startling hypotheses into his physiology, and drew from them conclusions which even upon his own showing were not always in accordance with experience. "On philosophical grounds," he was wont to say, when facts and theory thus confronted each other, "we must so accept it." Oken was extremely friendly with the students, and Agassiz, Braun, and Schimper (who joined them at Munich) passed an evening once a week at his house, where they listened to scientific papers or discussed scientific matters, over a pipe and a glass of beer. They also met once a week to drink tea at the house of Professor von Martius, where, in like manner, the conversation turned upon scientific subjects, unless something interesting in general events gave it a different turn. Still more beloved was Dollinger, whose character they greatly esteemed and admired while they delighted in his instruction. Not only did they go to him daily, but he also came often to see them, bringing botanical specimens to Braun, or looking in upon Agassiz's breeding experiments, in which he took the liveliest interest, being always ready with advice or practical aid. The fact that Agassiz and Braun had their room in his house made intercourse with him especially easy. This room became the rendezvous of all the aspiring, active spirits among the young naturalists at Munich, and was known by the name of "The Little Academy." Schimper, no less than the other two, contributed to the vivid, enthusiastic intellectual life, which characterized their meetings. Not so happy as Agassiz and Braun in his later experience, the promise of his youth was equally brilliant; and those who knew him in those early days remember his charm of mind and manner with delight. The friends gave lectures in turn on various subjects, especially on modes of development in plants and animals. These lectures were attended not only by
