Further, Sir Henry S. Maine has opened fresh ground, and perhaps (if he will permit me to say so) even to some extent narrowed the area within which the theory of archaic free village communities can be applied, by widening the range of investigation in yet another direction. In his lectures on the 'Early History of Institutions' he has turned his telescope upon the _tribal_ communities, and especially the 'tribal system' of the Brehon laws, and tried to dissolve parts of its mysterious nebulæ into stars--a work in which he has been followed by Mr. W. F. Skene with results which give a peculiar interest to the third volume of that learned writer's valuable work on 'Celtic Scotland.' Lastly, under the close examination of Dr. Landau and Professors Hanssen and Meitzen, the open-field system itself has been found in Germany to take several distinct forms, corresponding, in part at least, with differences in economic conditions, if not directly with various stages in economic development, from the early tribal to the later manorial system. It is very much to be desired that the open-field system of the various districts of France should be carefully studied in the same way. An examination of its widely extended modern remains could hardly fail to throw important light upon the contents of the cartularies which have been published in the 'Collection de Documents Inédits sur l'histoire de France,' amongst which the '_Polyptique d'Irminon_,' with M. Guérard's invaluable preface, is pre-eminently useful. In the meantime, whilst students had perhaps been too exclusively absorbed in working in the rich mine of early German institutions, Mr. Coote has done service in recalling attention in his 'Neglected Fact in English History' and his 'Romans of Britain' to the evidences which remain of the survival of Roman influences in English institutions, even though it may be true that some of his conclusions may require reconsideration. The details of the later Roman provincial government, and of the economic conditions of the German and British provinces, remain so obscure even after the labours of Mommsen, Marquardt, and Madvig, that he who attempts to build a bridge across the gulf of the Teutonic conquests between Roman and English institutions still builds it somewhat at a venture. It is interesting to find that problems connected with early English and German Economic History are engaging the careful and independent research also of American students. The contributions of Mr. Denman Ross, of Cambridge, Massachusetts, and Professor Allen, of the University of Wisconsin, will be welcomed by fellow-students of these questions in the old country.
