5. Besides these books of actual Services there was another, absolutely necessary for the right understanding and definite use of those already mentioned. This was the _Ordinale_, or book containing the general rules relating to the _Ordo divini servitii_. It is the _Ordinarius_ or _Breviarius_ of many Continental churches. Its method was to go through the year and show what was to be done; what days were to take precedence of others; and how, under such circumstances, the details of the conflicting Services were to be dealt with. The basis of such a book would be either the well-known Sarum _Consuetudinarium_, called after St. Osmund, but really drawn up in the first quarter of the thirteenth century, the Lincoln _Consuetudinarium_ belonging to the middle of the same century, or other such book. By the end of the fifteenth century Clement Maydeston's _Directorium Sacerdotum_, or Priests' Guide, had superseded all such books, and came itself to be called the Sarum _Ordinale_, until, about 1508, the shorter Ordinal, under the name of _Pica Sarum_, "the rules called the Pie," having been cut up and re-distributed according to the seasons, came to be incorporated in the text of all the editions of the Sarum Breviary. H. B. CAMBRIDGE, _March 17, 1881_. Mr Micklethwaite has kindly pointed out to me the following passage from the Cistercian _Consuetudines_ (Guignard, _Documents inédits_, Dijon, 1878, p. 174), cap. LXXII, "Nullus ingrediatur coquinam excepto cantore et scriptoribus ad planandam tabulam, ad liquefaciendum incaustum, ad exsiccandum pergamenum...." That is, the kitchen fire might be used for melting the wax on the tablets, so that a fresh list of names could be written (see above, p. 8), for liquefying frozen ink, and for drying the vellum skins ready for writing on.
