Arundel 377, 13th century, well-written small quarto, fols. 88-103, “Philosophia magistri danielis de merlai ad iohannem Norwicensem episcopum ... / ... Explicit liber de naturis inferiorum et superiorum.” Until very recently this was supposed to be the only MS of Daniel’s sole extant work. No other treatise has as yet been identified as his, but several other MSS may be noted of the whole or parts of the aforesaid “Philosophia” or “Liber de naturis inferiorum et superiorum.” Corpus Christi 95, 13th century, where, according to K. Sudhoff in the publication noted below, the first two or three books ascribed to William of Conches are really the work of Daniel of Morley. Berlin Latin Quarto 387, 12th century, 51 fols. Attention was called to it by Birkenmajer in the publication noted below. It has many slips of copyists and is regarded by him as neither the original nor a direct copy thereof. For the MS to be written in the twelfth century this would require a very rapid multiplication and dissemination of Daniel’s treatise which was at the earliest not composed until after 1175. The remaining MSS have not hitherto been noted by writers on Daniel: CUL 1935 (Kk. I. 1), 13th century, small folio, fols. 98r-105r (and not to 115r, as stated in the MSS catalogue, which gives Daniel Morley as the author, but _De creatione mundi_ as the title). From rotographs of fols. 98r-v, 100r, and 105r, I judge that this copy is almost identical with Arundel 377 but somewhat less legible and accurate. Oriel 7, 14th century folio, fols. 194v-196v (191-193, according to Coxe), extracts from _De philosophia Danielis_, opening, “Nos qui mistice.”... They are immediately preceded by extracts from “Adelardi Bathoniensis ... de decisionibus naturalibus.” Corpus Christi 263, early 17thI’ll sp century, fols. 166v-67r, “Ex Daniele de Merlai” (or, “Merlac,” according to Coxe) “alias Morley in lib. de superioribus et inferioribus primo De creationis Mundi.” This MS is one of the notebooks of Brian Twyne, the Elizabethan antiquary, written in his own hand.
