Excerpt from The Cambridge History of British Foreign Policy, 1783-1919, Vol. 2 Besides those charged with the responsibilities or engaged in the work of the Cambridge University Press - which has recently suffered a very' heavy loss in the death of Mr A. R. Waller, for eleven years Secretary of the Syndicate - we have to thank more friends than can be enumerated here for their aid in the production of the present volume. Use has again been made of the generous loan of the Wallace Papers, already acknowledged in the Preface to our first volume. We have also to thank the relations of the late Sir Andrew Buchanan, G.C.B., and more especially Mr Henry Mellish of Hadsock Priory, Worksop, for allowing us to peruse two volumes of Sir Andrew's private correspondence in the years 1863-4, when he was our Ambassador at Berlin - one of them consisting of letters from his predecessor Lord Bloomfield, then at Vienna, and the other of miscellaneous correspondence. The former, in particular, is full of interest. They have, also, favoured us with the loan of Sir Andrew's letters concerning the Russian repudiation in 1870 of the Black Sea obligations of the Treaty of March 30th, 1856, privately printed for the use of the Foreign Office. Through Mr G. M. Trevelyan's kind intervention, access has been granted us by the present Earl Grey to the Howick Papers, throwing light on the period 1830-4, dealt with in Mr Trevelyan's Lord Grey of the Reform Bill. Among leading authorities on the subject of this work who have continued to interest themselves in its progress, we desire again to express our obligations to the Right Hon. Lord Sanderson, G.C.B., to the Right Hon. Sir Ernest Satow, G.C.M.G., whose most valuable Diplomatic Practice has, we are glad to say, already reached a second edition, to Professor Sir C. H. Firth, F.B.A., and other friends. No continued aid or encouragement would have been more valued by us than that of the late Sir George Prothero, in whom the study of History' in this country' has lost one of its chief guides and controllers. We have, as before, to thank Miss A. D. Greenwood for undertaking the complicated task of compiling the Index to this Volume, and Miss M. Pate for her unwearying assistance in preparing it for publication. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
