He lived in his own little house in Königstrasse, a structure half brick and half wood, with a gable cut into steps; it looked upon one of those winding canals which intersect each other in the middle of the ancient quarter of Hamburg, and which the great fire of 1842 had fortunately spared. [1] Sixty-three. (Tr.) [2] As Sir Humphry Davy died in 1829, the translator must be pardoned for pointing out here an anachronism, unless we are to assume that the learned Professor's celebrity dawned in his earliest years. (Tr.) It is true that the old house stood slightly off the perpendicular, and bulged out a little towards the street; its roof sloped a little to one side, like the cap over the left ear of a Tugendbund student; its lines wanted accuracy; but after all, it stood firm, thanks to an old elm which buttressed it in front, and which often in spring sent its young sprays through the window panes. My uncle was tolerably well off for a German professor. The house was his own, and everything in it. The living contents were his god-daughter Gräuben, a young Virlandaise of seventeen, Martha, and myself. As his nephew and an orphan, I became his laboratory assistant. I freely confess that I was exceedingly fond of geology and all its kindred sciences; the blood of a mineralogist was in my veins, and in the midst of my specimens I was always happy. In a word, a man might live happily enough in the little old house in the Königstrasse, in spite of the restless impatience of its master, for although he was a little too excitable--he was very fond of me. But the man had no notion how to wait; nature herself was too slow for him. In April, after he had planted in the terra-cotta pots outside his window seedling plants of mignonette and convolvulus, he would go and give them a little pull by their leaves to make them grow faster. In dealing with such a strange individual there was nothing for it but prompt obedience. I therefore rushed after him. CHAPTER II. A MYSTERY TO BE SOLVED AT ANY PRICE That study of his was a museum, and nothing else. Specimens of everything known in mineralogy lay there in their places in perfect order, and correctly named, divided into inflammable, metallic, and lithoid minerals. How well I knew all these bits of science! Many a time, instead of enjoying the company of lads of my own age, I had preferred dusting these graphites, anthracites, coals, lignites, and peats! And there were bitumens, resins, organic salts, to be protected from the least grain of dust; and metals, from iron to gold, metals whose current value altogether disappeared in the presence of the republican equality of scientific specimens; and stones too, enough to rebuild entirely the house in Königstrasse, even with a handsome additional room, which would have suited me admirably.
