The following list indicates all of the small-note ornaments I could locate in a fairly quick hunt.
Unless noted, these are present in c. 1736 autograph fair copy (D-B Mus. ms. Bach P 25). Other ornamental markings are not included in this tally.
I welcome any I have missed, which will be noted as errata on the original post.
NBA mvt. number / bar / part (comment, when necessary)
8 / b. 29 / Soprano (Flute tacet in this version)
30 / b. 65 / Vln. I
38c / b. 25 / Evangelist
39 / bb. 3-4, 11-14, 25, 27-29, 31-32, 34-35, 37-38, 41-43 / Vln. solo (see note * below)
39 / b. 37 / Vln. I (this is a Schleifer in the 1736 version)
39 / bb. 42, 44 / Alto (these are Schleifern in the 1736 version)
43 / b. 6 / Evangelist
49 / b. 33 / Flute
57 / b. 46 / Bass (this is a Schleifer in the 1736 version)
65 / b. 51 / Bass
68 / bb. 8, 20 / Flutes, Oboes, Violins (taken in da Capo as bb. 88, 100; but see also note ** below)
Other related notes:
26 / b. 31 / Jesus : two eighth notes rather than (as in 1736) small-note appoggiatura and quarter note
38a / b. 3 / Evangelist: the small-note C is absent, but there is an otherwise inexplicable natural sign (as if to cancel the # of the previous bar)
52 / bb. 16, 18 / Alto: two eighth notes rather than (as in 1736) small-note appoggiatura and quarter note
There are a few significant instances when the autograph fair copy lacks small-note ornaments that are nonetheless present in the corresponding set of parts (D-B Mus. ms. Bach St 110, Fas. 1):
6 / bb. 12, 36, and 68 / Flutes
* 39 / bb. 1, 15, 23, 33, 39 / Vln. solo (and a similar situation with Schleifern; see Dürr’s critical report, p. 184)
** 68 / bb. 6, 18, 32, and 44 / Flutes, Oboes, Violins (but only in Chor II parts; see critical report, p. 222)
