The Theory of Law Differentials

I have prepared this paper not with the idea that the information it contains is original, or the result of individual research on my part, but rather with the thought that some record should be made in the transactions of this Society of the interesting developments in the theory of law differentials which have grown out of the recent revision of the Workmen's Compensation Manual. In addition, it is hoped that this presentation may gain for the subject a wider range of discussion than is possible in committee work.
