But M. Mommsen's industry is beyond praise, and his practice of using the labours of English Editors, without insulting them, is worthy of all imitation[16]. Among the works to which reference will be found in our edition are the following: Coleridge's _Literary Remains_: Dr Guest's _History of English Rhythms_: _the Versification of Shakespeare_, by W. Sidney Walker, (1854), and _Criticisms_, by the same, 3 vols., post 8vo, (1860), edited by Mr Lettsom, who has also contributed in his notes some suggestions for the improvement of the text. It is to be regretted that these volumes have not been accompanied by an Index. Dr. Charles Badham's article in the _Cambridge Essays_, 1856, contains many ingenious suggestions. We have borrowed from several literary journals, the _Athenæum_, _Notes and Queries_, and the _Parthenon_, and from Magazines, the conjectures of their correspondents. When the real name of the correspondent, or what might be such, was signed, we have given it in our notes, as 'Hickson,' 'S. Verges' (from _Notes and Queries_). When the name was obviously fictitious, or when the article was not signed at all, we have noted it thus: 'Anon. (N. and Q.) conj.,' 'Anon. (Fras. Mag.) conj.,' &c., referring to _Notes and Queries_, _Fraser's Magazine_, &c. 'Spedding,' 'Bullock,' 'Lloyd,' 'Williams,' 'Wright,' indicate respectively our correspondents, Mr James Spedding, Mr John Bullock, of Aberdeen, the Rev. Julius Lloyd, Mr W. W. Williams, of Oxford, and Mr W. Aldis Wright, to each and all of whom we beg to return our best thanks. We have also to thank Mr Archibald Smith, Mr C. W. Goodwin, Mr Bolton Corney, Mr N. E. S. A. Hamilton, Mr J. Nichols, Mr Jourdain, Dr Brinsley Nicholson, Mr Halliwell, Dr Barlow, Mr Grant White, Mr B. H. Bright, Mr Henry A. Bright, and Mr Bohn, for friendly suggestions and kind offers of assistance. The proposed emendations, marked 'Anon. conj.' are those which we have not been able to trace, or those in which the authors have not sufficient confidence to acknowledge them. Those proposed with some confidence by the present editors are marked 'Edd. conj.' In conclusion, we commend this volume, the first product of long labour, to the indulgent judgement of critics. In saying this we are not merely repeating a stereotyped phrase. We have found errors in the work of the most accurate of our predecessors. We cannot hope to have attained perfect accuracy ourselves, especially when we consider the wide range which our collation has embraced, and the minute points which we have endeavoured to record, but at all events we have spared no pains to render our work as exact as we could. Those who have ever undertaken a similar task will best understand the difficulty, and will be most ready to make allowance for shortcomings. 'Expertus disces quam gravis iste labor.' W. G. C. J. G.
