I ought next to have gone to the hospital La Pitié, where I passed much of my time during those two years. But the people there would not know me, and my old master's name, Louis, is but a dim legend in the wards where he used to teach his faithful band of almost worshipping students. Besides, I have not been among hospital beds for many a year, and my sensibilities are almost as impressible as they were before daily habit had rendered them comparatively callous.
How strange it is to look down on one's venerated teachers, after climbing with the world's progress half a century above the level where we left them! The stethoscope was almost a novelty in those days. The microscope was never mentioned by any clinical instructor I listened to while a medical student. Nous avons changé tout cela is true of every generation in medicine,--changed oftentimes by improvement, sometimes by fashion or the pendulum-swing from one extreme to another.
On my way back from the hospital I used to stop at the beautiful little church St. Etienne du Mont, and that was one of the first places to which I drove after looking at my student-quarters. All was just as of old. The tapers were burning about the tomb of St. Genevieve. Samson, with the jawbone of the ass, still crouched and sweated, or looked as if he did, under the weight of the pulpit. One might question how well the preacher in the pulpit liked the suggestion of the figure beneath it. The sculptured screen and gallery, the exquisite spiral stairways, the carved figures about the organ, the tablets on the walls,--one in particular relating the fall of two young girls from the gallery, and their miraculous protection from injury,--all these images found their counterpart in my memory. I did not remember how very beautiful is the stained glass in the charniers, which must not be overlooked by visitors.
It is not far from St. Etienne du Mont to the Pantheon. I cannot say that there is any odor of sanctity about this great temple, which has been consecrated, if I remember correctly, and, I will not say desecrated, but secularized from time to time, according to the party which happened to be uppermost. I confess that I did not think of it chiefly as a sacred edifice, or as the resting-place, more or less secure, of the "grands hommes" to whom it is dedicated. I was thinking much more of Foucault's grand experiment, one of the most sublime visible demonstrations of a great physical fact in the records of science. The reader may not happen to remember it, and will like, perhaps, to be reminded of it. Foucault took advantage of the height of the dome, nearly three hundred feet, and had a heavy weight suspended by a wire from its loftiest point, forming an immense pendulum,--the longest, I suppose, ever constructed. Now a moving body tends to keep its original plane of movement, and so the great pendulum, being set swinging north and south, tended to keep on in the same direction. But the earth was moving under it, and as it rolled from west to east the plane running through the north and south poles was every instant changing. Thus the pendulum appeared to change its direction, and its deviation was shown on a graduated arc, or by the marks it left in a little heap of sand which it touched as it swung. This experiment on the great scale has since been repeated on the small scale by the aid of other contrivances.
My thoughts wandered back, naturally enough, to Galileo in the Cathedral at Pisa. It was the swinging of the suspended lamp in that edifice which set his mind working on the laws which govern the action of the pendulum. While he was meditating on this physical problem, the priest may have been holding forth on the dangers of meddling with matters settled by Holy Church, who stood ready to enforce her edicts by the logic of the rack and the fagot. An inference from the above remarks is that what one brings from a church depends very much on what he carries into it.
The next place to visit could be no other than the Café Procope. This famous resort is the most ancient and the most celebrated of all the Parisian cafés. Voltaire, the poet J. B. Rousseau, Marmontel, Sainte Foix, Saurin, were among its frequenters in the eighteenth century. It stands in the Rue des Fossés-Saint Germain, now Rue de l'Ancienne Comédie. Several American students, Bostonians and Philadelphians, myself among the number, used to breakfast at this café every morning. I have no doubt that I met various celebrities there, but I recall only one name which is likely to be known to most or many of my readers. A delicate-looking man, seated at one of the tables, was pointed out to me as Jouffroy. If I had known as much about him as I learned afterwards, I should have looked at him with more interest. He had one of those imaginative natures, tinged by constitutional melancholy and saddened by ill health, which belong to a certain class of poets and sentimental writers, of which Pascal is a good example, and Cowper another. The world must have seemed very cruel to him. I remember that when he was a candidate for the Assembly, one of the popular cries, as reported by the newspapers of the time, was A bas le poitrinaire! His malady soon laid him low enough, for he died in 1842, at the age of forty-six. I must have been very much taken up with my medical studies to have neglected my opportunity of seeing the great statesmen, authors, artists, orators, and men of science outside of the medical profession. Poisson, Arago, and Jouffroy are all I can distinctly recall, among the Frenchmen of eminence whom I had all around me.
The Café Procope has been much altered and improved, and bears an inscription telling the date of its establishment, which was in the year 1689. I entered the cafe, which was nearly or quite empty, the usual breakfast hour being past.
Garçon! Une tasse de café.
If there is a river of mneme as a counterpart of the river lethe, my cup of coffee must have got its water from that stream of memory. If I could borrow that eloquence of Jouffroy which made his hearers turn pale, I might bring up before my readers a long array of pallid ghosts, whom these walls knew well in their earthly habiliments. Only a single one of those I met here still survives. The rest are mostly well-nigh forgotten by all but a few friends, or remembered chiefly in their children and grandchildren.
"How much?" I said to the garçon in his native tongue, or what I supposed to be that language. "Cinq sous," was his answer. By the laws of sentiment, I ought to have made the ignoble sum five francs, at least. But if I had done so, the waiter would undoubtedly have thought that I had just come from Charenton. Besides, why should I violate the simple habits and traditions of the place, where generation after generation of poor students and threadbare Bohemians had taken their morning coffee and pocketed their two lumps of sugar? It was with a feeling of virile sanity and Roman self-conquest that I paid my five sous, with the small additional fraction which I supposed the waiter to expect, and no more.
