On October 3, 1881, William Henry Rawle, the distinguished Philadelphia lawyer and scholar, addressed students at the University of Pennsylvania Law School hoping to illustrate, ‘in a very general and elementary way,’ the differences between the growth of English and early Pennsylvania jurisprudence. ‘It would have been more interesting and more broadly useful,’ Rawle apologized to his audience, ‘if the attempt could have been extended to embrace the other colonies which afterwards became the United States, for there would have been not only the contrast between the mother country and her colonies, but the contrast between the colonies themselves.’ Rawle was confident that such an examination would have revealed how ‘in some cases, one colony followed or imitated another in its alteration of the law which each had brought over, and how, in others, the law was changed in one colony to suit its needs, all unconscious of similar changes in another.’ ‘Unhappily,’ Rawle explained, ‘this must be the History of the Future for the materials have as yet been sparingly given to the world.’
