This work has been compiled in the belief that there is a need for a concise and simply worded text-book which will serve as an introduction to the standard authorities. Whilst care has been taken to give in a condensed form the essential principles of Roman Law, as they are to be found in the texts of Justinian and Gaius, other information has been added which it is hoped will prove of assistance to the student, and English parallels have been given in certain instances.
