WIERZCHOWNIA (Adam de), Polish gentleman, who, after the last division of Poland, found refuge in Sweden, where he sought consolation in the study of chemistry, a study for which he had always felt a strong liking. Poverty compelled him to give up his study, and he joined the French army. In 1809, while on the way to Douai, he was quartered for one night with M. Balthazar Claes. During a conversation with his host, he explained to him his ideas on the subject of "identity of matter" and the absolute, thus bringing misfortune on a whole family, for from that moment Balthazar Claes devoted time and money to this quest of the absolute. Adam de Wierzchownia, while dying at Dresden, in 1812, of a wound received during the last wars, wrote a final letter to Balthazar Claes, informing him of the different thoughts relative to the search in question, which had been in his mind since their first meeting. By this writing, he increased the misfortunes of the Claes family. Adam de Wierzchownia had an angular wasted countenance, large head which was bald, eyes like tongues of fire, a large mustache. His calmness of manner frightened Madame Balthazar Claes.[*] [The Quest of the Absolute.]
