Jules Verne,
Journey into the Interior of the Earth…
(1877)
“ 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. ”
