Were I to leave Munich now, I must separate myself from Agassiz and Schimper, which would be neither agreeable nor advantageous for me, nor would it be friendly toward them. We will not shorten the time, already too scantly measured, which we may still spend so quietly, so wholly by ourselves, but rather, as long as it lasts, make the best use of it in a mutual exchange of what we have learned, trying to encourage each other in the right path, and drawing more closely together for our whole life to come. Agassiz is to stay till the end of the month; during this time he will give us lectures in anatomy, and I shall learn a good deal of zoology. Beside all this one thing is certain; namely, that we can review our medical work much more quietly and uninterruptedly here than in Carlsruhe. Add to this, the advantage we enjoy here of visiting the hospitals. . . The time passes delightfully with us of late, for Agassiz has received several baskets of books from Cotta, among others, Schiller's and Goethe's complete works, the Conversations-Lexicon, medical works, and works on natural history. How many books a man may receive in return for writing only one! They are, of course, deducted from his share of the profits. Yesterday we did nothing but read Goethe the whole day. A brief account of Agassiz's university life, dictated by himself, may fitly close the record of this period. He was often urged to put together a few reminiscences of his life, but he lived so intensely in the present, every day bringing its full task, that he had little time for retrospect, and this sketch remained a fragment. It includes some facts already told, but is given almost verbatim, because it forms a sort of summary of his intellectual development up to this date. "I am conscious that at successive periods of my life I have employed very different means and followed very different systems of study. I may, therefore, be allowed to offer the result of my experience as a contribution toward the building up of a sound method for the promotion of the study of nature.
