 middle of the room, he kept order by means of a whip suspended at his side. A bigger boy, Bartels by name, used to cut quill pens, and assist the smaller boys in their lessons. He became a friend of Gauss, and would procure mathematical books, which they read together. Bartels subsequently rose to be a professor in the University of Dorpat, where he died. At the parish school the boys of fourteen to fifteen years were being examined in arithmetic one day, when Gauss stepped forward and, to the astonishment of Büttner, requested to be examined at the same time. Büttner, thinking to punish him for his audacity, put a 'poser' to him, and awaited the result. Gauss solved the problem on his slate, and laid it face downward on the table, crying 'Here it is,' according to the custom. At the end of an hour, during which the master paced up and down with an air of dignity, the slates were turned over, and the answer of Gauss was found to be correct while many of the rest were erroneous. Büttner praised him, and ordered a special book on arithmetic for him all the way from Hamburg.

From the parish school Gauss went to the Catherine Gymnasium, although his father doubted whether he could afford the money. Bartels had gone there before him, and they read the higher mathematics. Gauss also devoted much of his time to acquiring the ancient and modern languages. From there he passed to the Carolinean College in the spring of 1792. Shortly before this the Duke Charles William Ferdinand of Braunschweig among others had noticed his talents, and promised to further his career.

In 1793 he published his first papers; and in the autumn of 1795 he entered the University of Gottingen. At this time he was hesitating between the pursuit of philology or mathematics; but his studies became more and more of the latter order. He discovered the division of the circle, a problem published in his Disquisitiones Arithmetic, and henceforth elected for mathematics. The method of least squares, was also discovered during his first term. On arriving home the duke received him in the friendliest manner, and he was promoted to Helmstedt, where with the assistance of his patron he published his Disquisitiones.

On January 1, 1801, Piazzi, the astronomer of Palermo, discovered a small planet, which he named Ceres Ferdinandia, and communicated the news by post to Bode of Berlin, and Oriani of Milan. The letter was seventy-two days in going,
