The terms used in these documents for different sorts of tithes, for the various produce of the soil, etc., etc., will be sought for in vain in any ordinary Latin Dictionary; for their explanation it will be necessary to consult a Glossary of mediæval or monastic terms. The most handy and accurate is the abridged edition of the Glossaries of Du Cange, Du Fresne, etc., in six vols. 8vo., published at Halle, between 1722-1784. Some such work will also be found indispensable in consulting the monastic Chartularies and many of the Records and Rolls. The majority of the terms will be found in the last two editions of Cowel’s “Interpreter,” 1708, and 1737, which can much more readily be met with than the larger glossaries; but there is great need for a one volume compendious glossary, and it is hoped that such a work may shortly be published. LISTS OF INCUMBENTS. Lists of rectors and vicars, giving the date of their institution, and the names of their respective patrons, are indispensable to a complete parochial history. They are, for the most part, to be obtained from the diocesan registers. This work, in several dioceses, will be found to involve no small labour, for Bishop’s registrars were not always particular to separate institutions from other Episcopal acts, and occasionally placed them in precise chronological order for the whole diocese, without any regard to archdeaconries and other minor divisions. But the trouble will be amply repaid by the numerous quaint and interesting little details that the searcher will be almost sure to discover. Many of our episcopal registers, or act books, are of supreme interest, and yet they are perhaps less known than any class of original documents. The dates at which these registers begin average about the year 1300. We give, for the first time in any manual, their respective initial years:--Canterbury, 1279; London, 1306; Winchester, 1282; Ely 1336; Lincoln, 1217; Lichfield, 1296; Wells, 1309; Salisbury, 1296; Exeter, 1257; Norwich, 1299; Worcester, 1268; Hereford, 1275; Chichester, 1397; Rochester, 1319; York, 1214; and Carlisle, 1292. The old registers of Durham are mostly lost, that of Bishop Kellaw, 1311-18, being the oldest. None of the Welsh Cathedrals have any registers older than the 16th century. Gaps are not unusual in the episcopal registers for some time subsequent to the Reformation, when the books were often kept in a slovenly fashion. These deficiencies can be generally supplied from the lists of institutions in the Augmentation Books at the P. R. O. It is scarcely necessary to say that no list of incumbents should be considered complete, until it has been carefully collated with the parish registers.
