Here he came to a pause, standing, still in the gray light of the growing day, with eyes whose joyous lustre forestalled the sun’s, and lips which seemed to laugh even in repose.
But presently those eyes, as quick as they were bright, glanced over the walls, the floor, the shelves, the phials, the mechanical inventions, and then rested full on my cylinder fixed to the table. He approached, examined it curiously, asked what it was. I explained. To gratify him I sat down and renewed my experiment, with equally ill success. The needle, which should have moved from west to south, describing an angle of from thirty degrees to forty or even fifty degrees, only made a few troubled, undecided oscillations.
“Tut,” cried the young man, “I see what it is; you have a wound in your right hand.”
That was true; I had burned my band a few days before in a chemical experiment, and the sore had not healed.
“Well,” said I, “and what does that matter?”
“Everything; the least scratch in the skin of the hand produces chemical actions on the electric current, independently of your will. Let me try.”
He took my place, and in a moment the needle in the galvanometer responded to his grasp on the cylinder, exactly as the inventive philosopher had stated to be the due result of the experiment.
I was startled.
“But how came you, Mr. Margrave, to be so well acquainted with a scientific process little known, and but recently discovered?”
“I well acquainted! not so. But I am fond of all experiments that relate to animal life. Electricity, especially, is full of interest.”
On that I drew him out (as I thought), and he talked volubly. I was amazed to find this young man, in whose brain I had conceived thought kept one careless holiday, was evidently familiar with the physical sciences, and especially with chemistry, which was my own study by predilection. But never had I met with a student in whom a knowledge so extensive was mixed up with notions so obsolete or so crotchety. In one sentence he showed that he had mastered some late discovery by Faraday or Liebig; in the next sentence he was talking the wild fallacies of Cardan or Van Helmont. I burst out laughing at some paradox about sympathetic powders, which he enounced as if it were a recognized truth.
“Pray tell me,” said I, “who was your master in physics; for a cleverer pupil never had a more crack-brained teacher.”
“No,” he answered, with his merry laugh, “it is not the teacher’s fault. I am a mere parrot; just cry out a few scraps of learning picked up here and there. But, however, I am fond of all researches into Nature; all guesses at her riddles. To tell you the truth, one reason why I have taken to you so heartily is not only that your published work caught my fancy in the dip which I took into its contents (pardon me if I say dip, I never do more than dip into any book), but also because young —— tells me that which all whom I have met in this town confirm; namely, that you are one of those few practical chemists who are at once exceedingly cautious and exceedingly bold,—willing to try every new experiment, but submitting experiment to rigid tests. Well, I have an experiment running wild in this giddy head of mine, and I want you, some day when at leisure, to catch it, fix it as you have fixed that cylinder, make something of it. I am sure you can.”
“What is it?”
“Something akin to the theories in your work. You would replenish or preserve to each special constitution the special substance that may fail to the equilibrium of its health. But you own that in a large proportion of cases the best cure of disease is less to deal with the disease itself than to support and stimulate the whole system, so as to enable Nature to cure the disease and restore the impaired equilibrium by her own agencies. Thus, if you find that in certain cases of nervous debility a substance like nitric acid is efficacious, it is because the nitric acid has a virtue in locking up, as it were, the nervous energy,—that is, preventing all undue waste. Again, in some cases of what is commonly called feverish cold, stimulants like ammonia assist Nature itself to get rid of the disorder that oppresses its normal action; and, on the same principle, I apprehend, it is contended that a large average of human lives is saved in those hospitals which have adopted the supporting system of ample nourishment and alcoholic stimulants.”
“Your medical learning surprises me,” said I, smiling; “and without pausing to notice where it deals somewhat superficially with disputable points in general, and my own theory in particular, I ask you for the deduction you draw from your premises.”
“It is simply this: that to all animate bodies, however various, there must be one principle in common,—the vital principle itself. What if there be one certain means of recruiting that principle; and what if that secret can be discovered?”
“Pshaw! The old illusion of the mediaeval empirics.”
“Not so. But the mediaeval empirics were great discoverers. You sneer at Van Helmont, who sought, in water, the principle of all things; but Van Helmont discovered in his search those invisible bodies called gases. Now the principle of life must be certainly ascribed to a gas.11 And what ever is a gas chemistry should not despair of producing! But I can argue no longer now,—never can argue long at a stretch; we are wasting the morning; and, joy! the sun is up! See! Out! come out! out! and greet the great Lifegiver face to face.”
I could not resist the young man’s invitation. In a few minutes we were in the quiet lane under the glinting chestnut-trees. Margrave was chanting, low, a wild tune,—words in a strange language.
“What words are those,—no European language, I think; for I know a little of most of the languages which are spoken in our quarter of the globe, at least by its more civilized races.”
“Civilized race! What is civilization? Those words were uttered by men who founded empires when Europe itself was not civilized! Hush, is it not a grand old air?” and lifting his eyes towards the sun, he gave vent to a voice clear and deep as a mighty bell! The air was grand; the words had a sonorous swell that suited it, and they seemed to me jubilant and yet solemn. He stopped abruptly as a path from the lane had led us into the fields, already half-bathed in sunlight, dews glittering on the hedgerows.
“Your song,” said I, “would go well with the clash of cymbals or the peal of the organ. I am no judge of melody, but this strikes me as that of a religious hymn.”
“I compliment you on the guess. It is a Persian fire-worshipper’s hymn to the sun. The dialect is very different from modern Persian. Cyrus the Great might have chanted it on his march upon Babylon.”
“And where did you learn it?”
“In Persia itself.”
“You have travelled much, learned much,—and are so young and so fresh. Is it an impertinent question if I ask whether your parents are yet living, or are you wholly lord of yourself?”
“Thank you for the question,—pray make my answer known in the town. Parents I have not,—never had.”
“Never had parents!”
“Well, I ought
