This book contains selected cases, statutes, and a few other texts, relating to the history of English private law between 1194 and 1750. (Cases after 1750 are mostly available in the English Reports.) It may be used as a companion to the textbooks written by the compilers, but the purpose is different from that of a textbook. The original materials are here allowed to speak for themselves, without commentary. Most of them are reports of cases, which show how the common law evolved through argument. The losing arguments help to explain those which prevailed, and it is often instructive to know what was not argued. Most of the reports were written in law French, but they are here given in English translation, corrected or augmented from manuscripts, together with notes from the enrolled Latin records. Much of this material is not available in English translation elsewhere. The second impression (2019) contains corrections and additions.
