Thomas K. Arnold's Practical Introduction to Latin Prose Composition was first published in 1839, and was later edited and revised by George Granville Bradley (1821-1903) of University College, Oxford. This graduated and systematic approach to elements of Latin grammar and syntax has been the reference of choice for both teachers and students ever since, and has been revised, updated and redesigned several times. The book reissued here is a companion volume, first published by Bradley in 1881, which contains answers to all the exercises in Arnold's classic textbook. Long out of print, the Key provides model Latin solutions to all the exercises, as well as pedagogical footnotes and cross-references. A valuable resource for all instructors who use Bradley's Arnold, it will also be helpful to students wishing to write more accurately in Latin.
