“That Polish gentleman,” resumed Balthazar, “was named Adam de Wierzchownia. When you left us alone that evening in the parlor, we happened by chance to speak of chemistry. Compelled by poverty to give up the study of that science, he had become a soldier. It was, I think, by means of a glass of sugared water that we recognized each other as adepts. When I ordered Mulquinier to bring the sugar in pieces, the captain gave a start of surprise. ‘Have you studied chemistry?’ he asked. ‘With Lavoisier,’ I answered. ‘You are happy in being rich and free,’ he cried; then from the depths of his bosom came the sigh of a man,--one of those sighs which reveal a hell of anguish hidden in the brain or in the heart, a something ardent, concentrated, not to be expressed in words. He ended his sentence with a look that startled me. After a pause, he told me that Poland being at her last gasp he had taken refuge in Sweden. There he had sought consolation for his country’s fate in the study of chemistry, for which he had always felt an irresistible vocation. ‘And I see you recognize as I do,’ he added, ‘that gum arabic, sugar, and starch, reduced to powder, each yield a substance absolutely similar, with, when analyzed, the same qualitative result.’ “He paused again; and then, after examining me with a searching eye, he said confidentially, in a low voice, certain grave words whose general meaning alone remains fixed on my memory; but he spoke with a force of tone, with fervid inflections, with an energy of gesture, which stirred my very vitals, and struck my imagination as the hammer strikes the anvil. I will tell you briefly the arguments he used, which were to me like the live coal laid by the Almighty upon Isaiah’s tongue; for my studies with Lavoisier enabled me to understand their full bearing.
