I was left, I say, as part of the lock, stock, and barrel, at Wimblehurst with my new master, a Mr. Mantell; who plays no part in the progress of this story except in so far as he effaced my uncle’s traces. So soon as the freshness of this new personality faded, I began to find Wimblehurst not only a dull but a lonely place, and to miss my aunt Susan immensely. The advertisements of the summer terms for Cough Linctus were removed; the bottles of coloured water—red, green, and yellow—restored to their places; the horse announcing veterinary medicine, which my uncle, sizzling all the while, had coloured in careful portraiture of a Goodwood favourite, rewhitened; and I turned myself even more resolutely than before to Latin (until the passing of my preliminary examination enabled me to drop that), and then to mathematics and science. There were classes in Electricity and Magnetism at the Grammar School. I took a little “elementary” prize in that in my first year and a medal in my third; and in Chemistry and Human Physiology and Sound, Light and Heat, I did well. There was also a lighter, more discursive subject called Physiography, in which one ranged among the sciences and encountered Geology as a process of evolution from Eozoon to Eastry House, and Astronomy as a record of celestial movements of the most austere and invariable integrity. I learnt out of badly-written, condensed little text-books, and with the minimum of experiment, but still I learnt. Only thirty years ago it was, and I remember I learnt of the electric light as an expensive, impracticable toy, the telephone as a curiosity, electric traction as a practical absurdity. There was no argon, no radium, no phagocytes—at least to my knowledge, and aluminium was a dear, infrequent metal. The fastest ships in the world went then at nineteen knots, and no one but a lunatic here and there ever thought it possible that men might fly.
