WORKS OF REFERENCE. —The Post Office London Directory for 1920

(Kelly's Directories, 3 vols., 64s. net), the hundred and twenty-first annual issue, is a wonderful compilation. We always feel that the editors who produce year by year this exhaustive and infallible guide to the myriads of Londoners could prepare a directory of the human race if they cared to try. The division of the book into three parts, which was adopted some years ago, is a groat convenience.—Debretee Peerage, Baronetage, Knightage, and Companionage for 1920, edited by Arthur G. M. Hesilrigo (Dean, 73s. 6d. net), is larger than ever because it includes the innumerable recipients of new Orders. In the opening pages is the final Roll of Honour, containing the names of 3,150 sailors and soldiers killed in the war who were formerly included in Debreti. This melan- shay. total represents nearly a tenth of the death-roll of British officers.—The Live Stock Journal Annual for 1920 (irmton, 2s. net) contains a number of readable articles on horses, cattle, and other livestock, and some interesting photographs.
