Louis Agassiz: His Life and Correspondence Part 8

I think I forgot to mention the arrival of Braun six weeks after me. I had a double pleasure in his coming, for he brought with him his younger brother, a charming fellow, and a distinguished pupil of the polytechnic school of Carlsruhe. He means to be a mining engineer, and comes to study such collections at Paris as are connected with this branch. You cannot imagine what happiness and comfort I have in my relations with Alexander; he is so good, so cultivated and high-minded, that his friends.h.i.+p is a real blessing to me. We both feel very much our separation from the elder Schimper, who, spite of his great desire to join us at Carlsruhe and accompany us to Paris, was not able to leave Munich. . .

P.S. My love to Auguste. To-day (Sunday) I went again to see M.

Humboldt about Auguste's* (* Concerning a business undertaking in Mexico.) plan, but did not find him.

Then follow several pages, addressed to his father, in answer to the request contained in one of his last letters that Louis would tell him as much as he thinks he can understand of his work. There is something touching in this little lesson given by the son to the father, as showing with what delight Louis responded to the least touch of parental affection respecting his favorite studies, so long looked upon at home with a certain doubt and suspicion. The whole letter is not given here, as it is simply an elementary treatise on geology; but the close is not without interest as relating to the special investigations on which he was now employed.

"The aim of our researches upon fossil animals is to ascertain what beings have lived at each one of these (geological) epochs of creation, and to trace their characters and their relations with those now living; in one word, to make them live again in our thought. It is especially the fishes that I try to restore for the eyes of the curious, by showing them which ones have lived in each epoch, what were their forms, and, if possible, by drawing some conclusions as to their probable modes of life. You will better understand the difficulty of my work when I tell you that in many species I have only a single tooth, a scale, a spine, as my guide in the reconstruction of all these characters, although sometimes we are fortunate enough to find species with the fins and the skeletons complete. . .

"I ask pardon if I have tired you with my long talk, but you know how pleasant it is to ramble on about what interests us, and the pleasure of being questioned by you upon subjects of this kind has been such a rare one for me, that I have wished to present the matter in its full light, that you may understand the zeal and the enthusiasm which such researches can excite."

To this period belongs a curious dream mentioned by Aga.s.siz in his work on the fossil fishes.* (* "Recherches sur les Poissons Fossiles". Cyclopoma spinosum Aga.s.siz. Volume 4 tab 1, pages 20, 21.) It is interesting both as a psychological fact and as showing how, sleeping and waking, his work was ever present with him. He had been for two weeks striving to decipher the somewhat obscure impression of a fossil fish on the stone slab in which it was preserved. Weary and perplexed he put his work aside at last, and tried to dismiss it from his mind. Shortly after, he waked one night persuaded that while asleep he had seen his fish with all the missing features perfectly restored. But when he tried to hold and make fast the image, it escaped him. Nevertheless, he went early to the Jardin des Plantes, thinking that on looking anew at the impression he should see something which would put him on the track of his vision. In vain,--the blurred record was as blank as ever.

The next night he saw the fish again, but with no more satisfactory result. When he awoke it disappeared from his memory as before.

Hoping that the same experience might be repeated, on the third night he placed a pencil and paper beside his bed before going to sleep. Accordingly toward morning the fish reappeared in his dream, confusedly at first, but at last with such distinctness that he had no longer any doubt as to its zoological characters. Still half dreaming, in perfect darkness, he traced these characters on the sheet of paper at the bedside. In the morning he was surprised to see in his nocturnal sketch features which he thought it impossible the fossil itself should reveal. He hastened to the Jardin des Plantes, and, with his drawing as a guide, succeeded in chiseling away the surface of the stone under which portions of the fish proved to be hidden. When wholly exposed it corresponded with his dream and his drawing, and he succeeded in cla.s.sifying it with ease. He often spoke of this as a good ill.u.s.tration of the well-known fact, that when the body is at rest the tired brain will do the work it refused before.

TO HIS FATHER AND MOTHER.

PARIS, March, 1832.

. . .I am still so agitated and so surprised at what has just happened that I scarcely believe what my eyes tell me.

I mentioned in a postscript to my last letter that I had called yesterday on M. de Humboldt, whom I had not seen for a long time, in order to speak to him concerning Auguste's affair, but that I did not find him. In former visits I had spoken to him about my position, and told him that I did not well know what course to take with my publisher. He offered to write to him, and did so more than two months ago. Thus far, neither he nor I have had any answer.

This morning, just as I was going out, a letter came from M. de Humboldt, who writes me that he is very uneasy at receiving no reply from Cotta, that he fears lest the uncertainty and anxiety of mind resulting from this may be injurious to my work, and begs me to accept the inclosed credit of a thousand francs. . .--Oh! if my mother would forget for one moment that this is the celebrated M.

de Humboldt, and find courage to write him only a few lines, how grateful I should be to her. I think it would come better from her than from papa, who would do it more correctly, no doubt, but perhaps not quite as I should like. Humboldt is so good, so indulgent, that you should not hesitate, dear mother, to write him a few lines. He lives Rue du Colombier, Number 22; address, quite simply, M. de Humboldt. . .

In the agitation of the moment the letter was not even signed.

The following note from Humboldt to Mme. Aga.s.siz, kept by her as a precious possession, shows that in answer to her son's appeal his mother took her courage, as the French saying is, "with both hands," and wrote as she was desired.

FROM HUMBOLDT TO MME. AGa.s.sIZ.

PARIS, April 11, 1832.

I should scold your son, Madame, for having spoken to you of the slight mark of interest I have been able to show him; and yet, how can I complain of a letter so touching, so n.o.ble in sentiment, as the one I have just received from your hand. Accept my warmest thanks for it. How happy you are to have a son so distinguished by his talents, by the variety and solidity of his acquirements, and, withal, as modest as if he knew nothing,--in these days, too, when youth is generally characterized by a cold and scornful amour-propre. One might well despair of the world if a person like your son, with information so substantial and manners so sweet and prepossessing, should fail to make his way. I approve highly the Neuchatel plan, and hope, in case of need, to contribute to its success. One must aim at a settled position in life.

Pray excuse, Madame, the brevity of these lines, and accept the a.s.surance of my respectful regard.

HUMBOLDT.

The letter which lifted such a load of care from Louis and his parents was as follows:--

HUMBOLDT TO LOUIS AGa.s.sIZ.

PARIS, March 27, 1832.

I am very uneasy, my dearest M. Aga.s.siz, at being still without any letter from Cotta. Has he been prevented from writing by business, or illness perhaps? You know how tardy he always is about writing.

Yesterday (Monday) I wrote him earnestly again concerning your affair (an undertaking of such moment for science), and urged upon him the issuing of the fossil and fresh-water fishes in alternate numbers. In the mean time, I fear that the protracted delay may weigh heavily on you and your friends. A man so laborious, so gifted, and so deserving of affection as you are should not be left in a position where lack of serenity disturbs his power of work.

You will then surely pardon my friendly goodwill toward you, my dear M. Aga.s.siz, if I entreat you to make use of the accompanying small credit. You would do more for me I am sure. Consider it an advance which need not be paid for years, and which I will gladly increase when I go away or even earlier. It would pain me deeply should the urgency of my request made in the closest confidence, --in short, a transaction as between two friends of unequal age, --be disagreeable to you. I should wish to be pleasantly remembered by a young man of your character.

Yours, with the most affectionate respect,

ALEXANDER HUMBOLDT.

With this letter was found the following note of acknowledgment, scrawled in almost illegible pencil marks. Whether sent exactly as it stands or not, it is evidently the first outburst of Aga.s.siz's grat.i.tude.

My benefactor and friend,--it is too much; I cannot find words to tell you how deeply your letter of to-day has moved me. I have just been at your house that I might thank you in person with all my heart; but now I must wait to do so until I have the good fortune to meet you. At what a moment does your help come to me! I inclose a letter from my dear mother that you may understand my whole position. My parents will now readily consent that I should devote myself entirely to science, and I am freed from the distressing thought that I may be acting contrary to their wishes and their will. But they have not the means to help me, and had proposed that I should return to Switzerland and give lessons either in Geneva or Lausanne. I had already resolved to follow this suggestion in the course of next summer, and had also decided to part with Mr.

d.i.n.kel, my faithful companion, as soon as he should have finished the most indispensable drawings of the fossils on which he is now engaged here. I meant to tell you of this on Sunday, and now to-day comes your letter. Imagine what must have been my feeling, after having resolved on renouncing what till now had seemed to me n.o.blest and most desirable in life, to find myself unexpectedly rescued by a kind, helpful hand, and to have again the hope of devoting my whole powers to science,--you can judge of the state into which your letter has thrown me. . .

Soon after this event Aga.s.siz made a short excursion with Braun and d.i.n.kel to the coast of Normandy; worth noting, because he now saw the sea for the first time. He wrote home: "For five days we skirted the coast from Havre to Dieppe; at last I have looked upon the sea and its riches. From this excursion of a few days, which I had almost despaired of making, I bring back new ideas, more comprehensive views, and a more accurate knowledge of the great phenomena presented by the ocean in its vast expanse."

Meanwhile the hope he had always entertained of finding a professors.h.i.+p of natural history in his own country was ripening into a definite project. His first letter on this subject to M.

Louis Coulon, himself a well-known naturalist, and afterward one of his warmest friends in Neuchatel, must have been written just before he received from Humboldt the note of the same date, which extricated him from his pecuniary embarra.s.sment.

AGa.s.sIZ TO LOUIS COULON.

PARIS, March 27, 1832.

. . .When I had the pleasure of seeing you last summer I several times expressed my strong desire to establish myself near you, and my intention of taking some steps toward obtaining the professors.h.i.+p of natural history to be founded in your Lyceum. The matter must be more advanced now than it was last year, and you would oblige me greatly by giving me some information concerning it. I have spoken of my project to M. de Humboldt, whom I often see, and who kindly interests himself about my prospects and helps me with his advice. He thinks that under the circ.u.mstances, and especially in my position, measures should be taken in advance.

There is another point of great importance for me about which I wished also to speak to you. Though you have seen but a small part of it, you nevertheless know that in my different journeys, partly through my relations with other naturalists, partly by exchange, I have made a very fair collection of natural history, especially rich in just those cla.s.ses which are less fully represented in your museum. My collection might, therefore, fill the gaps in that of the city of Neuchatel, and make the latter more than adequate for the ill.u.s.tration of a full course of natural history. Should an increase of your zoological collection make part of your plans for the Lyceum, I venture to believe that mine would fully answer your purpose. In that case I would offer it to you, since the expense of arranging it, the rent of a room in which to keep it, and, in short, its support in general, is beyond my means. I must find some way of relieving myself from this burden, although it will be hard to part with these companions of my study, upon which I have based almost all my investigations. I have spoken of this also to M. de Humboldt, who is good enough to show an interest in the matter, and will even take all necessary steps with the government to facilitate this purchase. You would render me the greatest service by giving me your directions about all this, and especially by telling me: 1. On whom the nomination to the professors.h.i.+p depends?

2. With whom the purchase of the collection would rest? 3. What you think I should do with reference to both? Of course you will easily understand that I cannot give up my collections except under the condition that I should be allowed the free use of them. . .

The answer was not only courteous, but kind, although some time elapsed before the final arrangements were made. Meanwhile the following letter shows us the doubts and temptations which for a moment embarra.s.sed Aga.s.siz in his decision. The death of Cuvier had intervened.

AGa.s.sIZ TO HUMBOLDT.

PARIS, May, 1832.

. . .I would not write you until I had definite news from Neuchatel. Two days ago I received a very delightful letter from M.

Coulon, which I hasten to share with you. I will not copy the whole, but extract the essential part. He tells me that he has proposed to the Board of Education the establishment of a professors.h.i.+p of natural history, to be offered to me. The proposition met with a cordial hearing. The need of such a professors.h.i.+p was unanimously recognized, but the President explained that neither would the condition of the treasury allow its establishment in the present year, nor could the proposition be brought before the Council of State until the opening of the new Lyceum.

Monsieur Coulon was commissioned to thank me, and to request me in the name of the board to keep the place in mind; should I prefer it, however, he doubts not that whatever the city could not do might be made good by subscription before next autumn, in which case I could enter upon office at once. He requests a prompt answer in order that he may make all needful preparations. Only too gladly would I have consulted you about various propositions made to me here in the last few days, and have submitted my course to your approval, had it not been that here, as in Neuchatel, a prompt answer was urged. Although guided rather by instinct than by anything else, I think, nevertheless, that I have chosen rightly.

In such moments, when one cannot see far enough in advance to form an accurate judgment upon deliberation, feeling is, after all, the best adviser; that inner impulse, which is a safe guide if other considerations do not confuse the judgment. This says to me, "Go to Neuchatel; do not stay in Paris." But I speak in riddles; I must explain myself more clearly. Last Monday Levrault sent for me in order to propose that Valenciennes and I should jointly undertake the publication of the Cuvierian fishes. . .I was to give a positive answer this week. I have carefully considered it, and have decided that an unconditional engagement would lead me away from my nearest aim, and from what I look upon as the task of my life. The already published volumes of the System of Ichthyology lie too far from the road on which I intend to pursue my researches. Finally, it seems to me that in a quiet retired place like Neuchatel, whatever may be growing up within me will have a more independent and individual development than in this restless Paris, where obstacles or difficulties may not perhaps divert me from a given purpose, but may disturb or delay its accomplishment. I will therefore so shape my answer to Levrault as to undertake only single portions of the work, the choice of these, on account of my interest in the fossil and the fresh-water fishes, being allowed me, with the understanding, also, that I should be permitted to have these collections in Switzerland and work them up there. From Paris, also, it would not be so easy to transfer myself to Germany, whereas I could consider Neuchatel as a provisional position from which I might be called to a German university. . .

In the mean time, while waiting hopefully the result of his negotiations with Neuchatel, Aga.s.siz had organized with his friends, the two Brauns, a bachelor life very like the one he and Alexander had led with their cla.s.smates in Munich. The little hotel where they lodged had filled up with young German doctors, who had come to visit the hospitals in Paris and study the cholera. Some of these young men had been their fellow-students at the university, and at their request Aga.s.siz and Braun resumed the practice of giving private lectures on zoology and botany, the whole being conducted in the most informal manner, admitting absolute freedom of discussion, as among intimate companions of the same age. Such an interchange naturally led to very genial relations between the amateur professors and their cla.s.s, and on the eve of Aga.s.siz's birthday (28th of May) his usual audience prepared for him a very pleasant surprise. Returning from a walk after dusk he found Braun in his room. Continuing his stroll within four walls, he and his friend paced the floor together in earnest talk, when, at a signal, Braun suddenly drew him to the window, threw it open, and on the pavement below stood their companions, singing a part song, composed in honor of Aga.s.siz. Deeply moved, he withdrew from the window in time to receive them as they trooped up the stairway to offer their good wishes. They presently led the way to another room which they had dressed with flowers, Aga.s.siz's name, among other decorations, being braided in roses beneath two federal flags crossed on the wall. Here supper was laid, and the rest of the evening pa.s.sed gayly with songs and toasts, not only for the hero of the feast and for friends far and near, but for the progress of science, the liberty of the people, and the independence of nations. There could be no meeting of ardent young Germans and Swiss in those days without some mingling of patriotic aspirations with the sentiment of the hour.
