[28a - 39 lines; 28b - 46 lines]
We recommend using the textual changes suggested by the Bach and the marginal notes of the Vilna Shas. This section is devoted to any other important corrections that Acharonim have pointed out in the Gemara, Rashi and Tosfos.
 Gemara 28a [line 7]:
The words "Kapa d'Chata Nagara b'Gavah" כפא דחטא נגרא בגווה
should be "Kapa d'Chat Nagara b'Gavah" כפא דחט נגרא בגווה (Rashi in all early printings, Rabeinu Chananel, Aruch)
or "Kapa d'Chak Nagara b'Gavah" כפא דחק נגרא בגווה (the Oxford manuscript)
 Gemara 28a [line 9]:
The words "Gira b'Girei Maktil" גירא בגירי מקטיל
should be "Gira'ah b'Gireih (with a Heh at the end) Maktil" גיראה בגירֵהּ (early printings)
1)[line 3]אשם תלויASHAM TALUY
(a)An Asham Taluy is a Korban offered by one who is in doubt as to whether he committed a transgression for which he must bring a Korban Chatas (Vayikra 5:17-19). The Korban consists of a ram worth two Sela'im. If the Makriv later discovers that he did indeed sin, he must offer a Korban Chatas. The Asham Taluy provides only temporary atonement during the period of doubt.
(b)If the Makriv discovers after offering his Korban that he did not sin, or if some other Pesul (such as Nosar) occurs, the ram must be disposed of. How it is to be disposed of is the subject of a disagreement between Tana'im. According to the Chachamim, it must be burned. Rebbi Yehudah is of the opinion that it must be buried.
2)[line 3]וחטאת העוף הבא על הספקCHATAS HA'OF HA'BA AL HA'SAFEK
(a)One may not offer an animal as a sacrifice when it is unclear whether or not he is obligated to do so. This is because of the possibility that doing so would be transgressing the prohibition of slaughtering, offering and eating Chulin ba'Azarah.
(b)Unlike other Korbanos, a Chatas ha'Of is not slaughtered, nor is it offered upon the Mizbe'ach. Rather, Melikah (see Background to Pesachim 34:14) is performed, and then its blood is sprinkled on the Mizbe'ach. One may therefore offer a Chatas ha'Of even when he is not certain that he is obligated to do so; however, it may not be eaten. For example, if a woman is uncertain as to whether or not she miscarried a fully formed child, she may bring a Chatas ha'Of so that she may eat Kodshim. The bird, however, is not eaten.
(c)What one must do with the carcass of this Chatas is the subject of a Machlokes. The Rabanan rule that a Chatas ha'Of ha'Ba Al ha'Safek must be burned, while Rebbi Yehudah rules that Yatilenah la'Amah — it should be thrown into the Amah-wide channel of water which passed through the Azarah of the Beis ha'Mikdash and emptied into the valley of Kidron.

10)[line 32]הא בחיטיHA B'CHITI- Kernels of wheat which have become Chametz must be scattered across the water, and not gathered together in a bag or sack and thrown in together. This is because they do not dissolve, and someone may come to find them.

18)[line 34]שפיר קאמר ליה רבי שמעוןSHAPIR KA'AMAR LEI REBBI SHIMON- that is, why does Rebbi Yehudah not understand, as Rebbi Shimon does, that Chametz is forbidden for only seven days just as Matzah is?
