. . .I have had a long talk about you with your uncle. He does not at all disapprove of your letters, of which I told him the contents. He only insists, as we do, on the necessity of a settled profession as absolutely essential to your financial position. Indeed, the natural sciences, however sublime and attractive, offer nothing certain in the future. They may, no doubt, be your golden bridge, or you may, thanks to them, soar very high, but--modern Icarus--may not also some adverse fortune, an unexpected loss of popularity, or, perhaps, some revolution fatal to your philosophy, bring you down with a somersault, and then you would not be sorry to find in your quiver the means of gaining your bread. Agreed that you have now an invincible repugnance to the practice of medicine, it is evident from your last two letters that you would have no less objection to any other profession by which money is to be made, and, besides, it is too late to make another selection. This being so, we will come to an understanding in one word: Let the sciences be the balloon in which you prepare to travel through higher regions, but let medicine and surgery be your parachutes. I think, my dear Louis, you cannot object to this way of looking at the question and deciding it. In making my respects to the professor of zoology, I have the pleasure to tell him that his uncle was delighted with his way of passing his evenings, and congratulates him with all his heart on his choice of a recreation. Enough of this chapter. I close it here, wishing you most heartily courage, health, success, and, above all, contentment. . . Upon this follows the answer to Louis's request for details about the "Society of Public Utility." It shows the intimate exchange of thought between father and son on educational subjects, but it is of too local an interest for reproduction here. The Easter vacation was devoted to a short journey, some account of which will be found in the next letter. The traveling party consisted of Agassiz, Braun, and Schimper, with two other students, who did not, however, remain with them during the whole trip. TO HIS FATHER. MUNICH, May 15, 1828. . . .Pleasant as my Easter journey was, I will give you but a brief account of it, for my enjoyment was so connected with my special studies that the details would only be tiresome to you. You know who were my traveling companions, so I have only to tell you of our adventures, assuredly not those of knights errant or troubadours. Could these gentry have been resuscitated, and have seen us starting forth in blouses, with bags or botanical boxes at our backs and butterfly-nets in our hands, instead of lance and buckler, they could hardly have failed to look down upon us with pity from the height of their grandeur.
