When vacation came, Braun took Agassiz to his home; a cultured place, rich in books, music, and collections of plants and animals. Agassiz was very happy there; possibly the happiness was increased by the fact that Braun had a lovely and artistic sister, Cecile. Agassiz wrote home, "My happiness would be perfect were it not for the painful thought which pursues me everywhere, that I live on your privations; yet it is impossible for me to diminish my expenses further. You would lift a great weight from my heart if you could relieve yourself of this burden by an arrangement with my uncle at Neuchâtel.... Otherwise I am well, going on as usual, always working as hard as I can, and I believe all the professors whose lectures I attend are satisfied with me." In the spring of 1827, when Agassiz was twenty, he was taken ill of typhus fever, and it was feared he would not recover. As soon as possible he was removed to Braun's home, and most tenderly cared for. When he became able, he went to his own home, at Orbe. From there he writes to Braun: "I had the good fortune to find at least thirty specimens of Bombinator obstetricans, with the eggs. Tell Dr. Leuckart that I will bring him some,--and some for you also. I kept several alive, laid in damp moss; after fourteen days the eggs were almost as large as peas, and the little tadpoles moved about inside in all directions. The mother stripped the eggs from her legs, and one of the little tadpoles came out, but died for want of water. Then I placed the whole mass of eggs in a vessel filled with water, and behold! in about an hour some twenty young ones were swimming freely about. I shall spare no pains to raise them, and I hope, if I begin aright, to make fine toads of them in the end. My oldest sister is busy every day in making drawings for me to illustrate their gradual development." In the fall of 1827, Agassiz and Braun, after spending a little more than a year at Heidelberg, went to the University of Munich, there meeting Schimper. He wrote home, that from one of his windows he could see "the whole chain of the Tyrolean Alps, as far as Appenzell.... It is a great pleasure to have at least a part of our Swiss mountains always in sight. To enjoy it the more, I have placed my table opposite the window, so that every time I lift my head my eyes rest on our dear country." At Munich, the young students were stimulated by the presence of many noted men. Döllinger lectured on comparative anatomy; Schelling, on philosophy; Oken, on natural history, physiology, and zoölogy; Martius, on botany. Agassiz and Braun roomed in Döllinger's house. This room soon became the intellectual centre for the bright men of the college, and was called "the little academy." Here different students gave lectures, each on his special subject of study; the professors, even, coming as listeners.
