the demisemiquaver passing notes are omitted; as is also the semiquaver passing note, bar 28.
IV. Is missing.
V. Is missing.
VI. Prelude:—at bar 10, two bars are erased and eight bars are substituted at the foot of the page, the eight bars accord with text; bar 18, and the seven bars that follow, accord with marginal reading; at bar 22, the under stave is in the alto clef till bar 26; after bar 37 two bars are inserted at the foot, the two bars accord with text. Fugue:—throughout like text.
VII. Prelude:—bar 30, like text; bar 49, the C in the upper stave is an octave lower; bar 66, no flat to D in bass. Fugue:—throughout like text.
VIII. Prelude:—nine sharps in the signature, on the same principle as signature of No. 3. Fugue:—signature like Prelude; bar 14, the second B is omitted; bar 18, like marginal reading.
IX. Prelude:—bar 9, second quaver in bass B not A; bar 21, no turn on A♯; bar 50, bass like neither text nor margin, but (e), this is substituted in the place of an erasure, apparently like text;
bar 54, no chord in the upper stave, simply E. Fugue:—bar 15, trill on tenor D; bar 18, no natural to second E in alto.
X. Prelude:—throughout like text. Fugue:—in bar 18 and similar ones, the quaver of the compound time is written exactly under (or over, as the case may be) the semiquaver of the simple time. This throws a light on like instances in Bach's works, notably so on, the way the Prelude in D (No. 5 of the Second Part) should be played; bars 70, 71, (f), so the Fugue ends.
XI. Prelude:—throughout like text. Fugue:—bar 12 and the seven bars that follow, in G clef; from bar 89 to the end is written at the bottom of the Prelude, with 'Final zur folgend Fuga.'
XII. Is missing.
XIII. Prelude:—nine sharps in the signature of both Prelude and Fugue, on the same principle as Nos. 3 and 8.
XIV. Prelude:—end of bar 18 (g);

Fugue:—signature like Prelude; from bar 6 the under stave is in the alto clef for two bars and three quarters; the latter half of bar 14 is as at (i); bar 32, the upper part enters at the commencement with a B minim.
XVIII. Prelude:—bars 12, 14, 15, 40, like margin. Fugue:—throughout like text.
