The MS. from which the text of the Nile Service is taken, is numbered Or. 4951, and is a recent acquisition of the British Museum. It consists of 69 paper leaves, measuring about 6£ ins. by 5 ins., with mostly 15 lines to a page. The quires, 7 in number, are of 10 leaves each (the last leaf being blank). The Syriac letters by which the quires are numbered are written in the middle of the lower margin, both on the last and the first page of each quire. Thus, on fol. 10b, the letter denotes the end of the first quire, and the same letter also stands on fol. 11a; the letters etc., are similarly written on foil. 20 b and 21 a, foil. 30b and 31a, etc. The only exception is the absence of the letter on fol. 61a. The style of writing, though smaller, approaches yery nearly to that of pi. xx (representing fol. 34 of Add. 14,664) in vol. iii of Wright's “Catalogue of the Syriac MSS. in the British Museum,” which has been assigned to the twelfth or thirteenth century. The letter “rlsh” is, with very few exceptions, written (with two dots instead of one), and the “daleth” is, as a rule, not distinguished by a dot below. There are no diacritic points below the letters, and points over the text (see the first facsimile, representing fol. 38b of the MS. chosen to exemplify some of the characteristics mentioned here)are mainly employed in the following cases:
