FOOTNOTES:
==========
(1) This is true according to all of the Tana'im except for Rebbi Yehudah. According to Rebbi Yehudah, if the mixture is Min b'Mino, it is not Batel. (According to TOSFOS here (81b and 82a, DH Rebbi Yehudah), Min b'Mino is not Batel according to Rebbi Yehudah only in the case of a liquid, because the taste of the Isur penetrates throughout the entire mixture. RASHI (81b, DH Rebbi Yehudah) and RABEINU TAM (in Tosfos to Zevachim 73a, DH Rebbi Yehudah) dispute this ruling.)
(2) An example of "Hefsed Mu'at," a minor loss, is a piece of Tahor meat from a Korban Chatas which becomes mixed with pieces of meat of Chulin. (This follows the interpretation of RASHI 81b, DH Divrei ha'Kol and 82a, DH ul'Reish Lakish. See Insights to 82a where we cite TOSFOS who disagrees and maintains that even when there is a Hefsed Mu'at, the Isur is Batel. According to Tosfos, only if the piece of Isur was "Re'uyah l'Hiskabed" is it not Batel.)
(3) According to the second version in Rashi (82a, DH Lishna Acharina), only an Isur *Kares* or *Misah b'Yedei Shamayim* (such as the Isur that prohibits a Zar from eating Terumah) is not Batel when it is "Kol she'Darko Limanos." (Nevertheless, when it is "Es she'Darko Limanos," even an Isur Lav such as Kil'ei ha'Kerem, or an Isur d'Rabanan such as Terumas Peros bi'Zeman ha'Zeh, is not Batel.)
(4) In the case of an Isur d'Oraisa that falls into a mixture of Min b'Mino, Rav Shisha brei d'Rav Idi rules that -- according to the way Reish Lakish understands the Tana of "Chatichah b'Chatichos" -- the Isur is not Batel. According to Rabah, only if an Isur *Kares* is in a mixture of Min b'Mino does the Isur not become Batel. (This follows Rashi's *first* interpretation of Rabah's statement.)
(5) The term "Isur d'Rabanan" according to Reish Lakish refers to an Isur similar to the Isur of Terumah today (when there is no Beis ha'Mikdash). Terumah of Peros in the time of the Beis ha'Mikdash, however, is treated like an Isur d'Oraisa, just like Terumah of grain, according to Reish Lakish (81a). (In contrast, according to Rebbi Yochanan, Terumas Peros is treated like an Isur d'Rabanan even in the times of the Beis ha'Mikdash; see Insights to 82a.)
(6) It is clear that this is the view of Reish Lakish, as is evidenced from the fact that the Beraisa specifically teaches Bitul in the case of an "Igul," an item which is "Kol she'Darko." This implies that an Isur d'Rabanan which is "*Es* she'Darko" would *not* be Batel. (This seems to be the intention of TOSFOS 81a, DH v'ha'Lo and DH Mai.)
