I am very conscious of the large number of debts which I need to acknowledge here, and also conscious that too long a list might seem inappropriate to the work that follows; Parturiunt montes: nascetur ridiculus mus. So, I wish to state at once that I am extremely grateful for much assistance that I have no room to catalogue here. I must first thank those institutions whose financial assistance made possible the research for this book, the University of Dundee, and the French government, which, through the agency of the British Council, awarded me a C.N.R.S. fellowship during the years 1967-8. I must also thank the University court of St Andrews University for granting me a term's sabbatical leave to permit me to do research in France. I also wish to take this opportunity, on the occasion of the publication of my first full-length book on French history, to thank the French government for their generous financial assistance over a period of more than ten years, from the time when I began research into French history. I am very grateful for the facilities and assistance provided by the French government and its educational institutions, extended so freely to foreign students, and I wish to record here my appreciation of the assistance that I have received at various times from the Centre National de la Recherche Scientifique, from COPAR, and from the Ministry of Education. I also wish to thank all those who guided my first steps as a student of the Third Republic, and especially MM. F. Goguel, O. Wormser and J. Millerand. I hope that they will accept these belated thanks, although their assistance was not directly relevant to this study.
I am extremely grateful to the custodians of the Balfour papers, the Milner papers, the Chamberlain papers and the Lloyd George papers
