In my book The Evolution of Law I sought to give a general theory of legal evolution based on detailed legal examples from which generalizations could be drawn, offering as few examples as were consistent with my case in order to present as clear a picture as possible. I was well aware as I was writing that some critics would regard the examples as mere isolated aberrations and for them and for other readers who, whether convinced of the thesis or not, would like further evidence, I want here to bring forward a few extra significant examples.
