As the Downing Professor of the Laws of England, F. W. Maitland lectured on equity at Cambridge for 18 years, ending in 1906. The lectures were first published in 1909 under the editorship of A. H. Chaytor and W. J. Whittaker. They were reprinted seven times before being published in 1936 in a second edition edited by J. Brunyate, who added some notes to Maitland's lectures. This edition is replicated here. Equity is an important aspect of English law. Its rules grew up to supplement Common Law and largely concern such matters as wills and trusts.
