Ever since 1894 he held that both the " Western " text of Acts (which he styles the (3 text) and its rival, the text of the great uncials (which he styles the a text), are due to the author's own hand.
Notes were often written in uncials; the use of majuscules or capitals for headings and for the initial letters of lines is well known.
There are at present two main systems: (1) Since the time of Wetstein it has been customary to employ capital letters, at first of the Latin and latterly also of the Greek and Hebrew alphabets, to designate the uncials, and Arabic figures to designate the minuscules.
There are not enough letters to cover the uncials, the same letter has to serve for various fragments which are quite unconnected except by the accident of simultaneous discovery, and no information is given about the MS. referred to.
Its relations to EFG are best discussed in Westcott and Hort's Introduction, §§ 335-337.] There are no other uncials equal in importance to the above.
