First printing of Brill's paper which was of seminal importance in the development of the discriminant of an algebraic number field.The definition of the discriminant of a general algebraic number field, K, was given by Dedekind in 1871. Hermite's theorem predates the general definition of the discriminant with Charles Hermite publishing a proof of it in 1857. In 1877, Alexander von Brill determined the sign of the discriminant.The present volume contain several other papers by influential contemporary mathematicians.
