1)[line 1]היא גופא תיחוץHI GUFA TEICHUTZ- it itself (the barrel) should intervene
2)[line 1]כלי חרשׂ אינו מטמא מגבוKELI CHERES EINO MITAMEI MI'GABO - earthenware utensils do not receive Tum'ah from their outside (TUM'AS KELEI CHERES)
(a)Klei Cheres are (baked) clay and earthenware utensils. They do not receive Tum'ah when an object of Tum'ah touches their outside. They only become Tamei when Tum'ah enters them (even if it does not touch the inside surface). Therefore, when they are covered with a Tzamid Pesil (a tight seal) they cannot become Tamei even if they are in the Ohel of a Mes, as is stated in Bamidbar 19:15. If they do become Tamei, they make any food or drink that enters them Tamei, even if it did not touch their inside surface.
(b)If clay and earthenware utensils become Tamei, they remain so until they are broken beyond use. Immersing them in a Mikvah does not change their status.
(c)If the mouth of the utensil is so small that a person cannot insert his finger into it, it has no possibility of becoming Tamei through a Zav (see Background to Bava Metzia 105:30). However, these utensils can become Tamei in the Ohel of a Mes, as long as they do not have a Tzamid Pasil to entirely seal them. Similarly, they can become Tamei if they come into contact with a k'Adashah of a Sheretz (see Background to Bava Kama 25:18).
(c)For a further discussion of the principles of Tum'os and Taharos, see Background to Nazir 54:13.
3)[line 2]דפומא לגאוD'FUMA L'GAV- its mouth is pointing inward
4)[line 5]ומטלוניותMATLONIYOS- strips of cloth; patches
5)[line 6]שלש על שלשSHALOSH AL SHALOSH (TUM'AS MES)
(a)A cloth must be at least three Etzba'os square in order to become Tamei Mes (see Background to Bava Kama 105:13) or Tamei Sheretz (see Background to Bava Metzia 58:26), since this size is still fit for use by the poor. One Etzba = approximately 1.9, 2.0 or 2.4 cm, depending upon the differing Halachic opinions. A cloth that is smaller than this is Tahor due to its insignificance.
(b)With regard to Tum'as Midras (see below, entry #17), a cloth must be a minimum of three Tefachim square in order to become Tamei Midras. A cloth is the only material that has this distinction; the minimum sizes for all other materials are measured in Tefachim, whether for Tum'as Mes, Midras, etc. (The word "Etzba'os" is feminine; therefore the Gemara uses Shalosh for Etzba'os. "Tefachim" is masculine, therefore the Gemara uses Sheloshah for Tefachim.)
6)[line 7]המדולדליןHA'MEDULDALIN- that are hanging (i.e. the limb or the flesh have not yet been entirely severed)
7)[line 7]ששכןSHE'SHACHAN- that nested
8)[line 8]ובן שְׁמֹנָהBEN SHEMONAH
(a)According to Chazal, a woman can give birth to a viable child only from a seven-month or a nine-month term of pregnancy. The child that is born from an eight-month term will not be viable. Even if he appears normal upon birth, it is assumed that he will not survive and will die from a birth defect shortly.
(b)The Amora'im argue as to whether the child born at the beginning, but before the end, of the ninth month ("l'Mekuta'in") can be viable. According to all opinions, however, a woman who gives birth before the end of the seventh month of pregnancy can bear a viable child. (For example, Shmuel ha'Navi was born after six months and two days, as mentioned in Yevamos 42a, based on the verse in Shmuel I 1:20).
(c)If the features of a baby born in the eighth month (especially the hair and nails) are fully developed, he is deemed by Rebbi to have developed in seven months, but to have lingered in the womb until the eighth month (Yevamos 80a). Therefore, he is considered a viable child. However, some rule that his viability is in question until he lives thirty days (or twenty years, according to Rashi - see Insights to Yevamos 80:1).

17)[line 19]ארבעה על ארבעהARBA'AH AL ARBA'AH (TUM'AS MIDRAS)
(a)A Zav (see Background to Bava Kama 24:5), Zavah (see Background to Bava Kama 24:2), Nidah (see Background to Kidushin 80:2b), or Yoledes (see Background to Kidushin 13:16), can cause objects (other than Klei Cheres - earthenware objects) that are under them to become Avos ha'Tum'ah, whether they touch them directly or not. The objects become Tamei Midras (lit. an object that is treaded upon), otherwise known as Mishkav or Moshav ha'Zav, ha'Zavah, etc. (or the Tachton, of a Zav, etc.). An object that is under these people becomes a Midras only if it was made for lying, sitting, or leaning upon.
(b)The Mishnah (Keilim 27:2) states that an item of clothing can receive Tum'as Midras if it is the size of Sheloshah Al Sheloshah (three Tefachim by three Tefachim). If it is smaller than that, it is not suitable for a Zav to sit upon and does not become Tamei through Midras. The minimum size for pieces of sack material (such as the Riska of our Gemara) is four square Tefachim. Leather (Or) and mats woven of reeds (Mapatz) have bigger minimum sizes (five and six square Tefachim, respectively). As mentioned above (entry #5:b), the sizes for sack material, leather and mats apply for all Tum'os.
(c)A person who touches (Maga) or carries (Masa) either a Midras or a Zav or Zavah themselves gets the status of Rishon l'Tum'ah, and so do the clothes he is wearing and other utensils (except for earthenware utensils) that he is touching at the time.
(d)Utensils or clothes that lie above the Zav or Zavah also get the status of a Rishon l'Tum'ah, whether he touches them or not. These are called the Elyon of a Zav or Zavah.

42)[line 28]באמתB'EMES- (lit. in truth) it is an accepted Halachah. (According to the Yerushalmi (Shabbos 1:3), "b'Emes Amru" translates as "it is a Halachah l'Moshe mi'Sinai." From the Rambam's introduction to Perush ha'Mishnayos, though, it may be inferred that this is true only when "b'Emes Amru" is stated in a Mishnah (as in our Mishnah), but not when it is mentioned in a Beraisa. Rashi to Sukah 38a DH b'Emes Amru applies the Yerushalmi's translation even to a "b'Emes Amru" that is mentioned in a Beraisa. Accordingly, it could mean "it is as clear as a Halachah l'Moshe mi'Sinai" - see MAHARATZ CHAYOS to Beitzah 17a.) See Background to Bava Metzia 60:11.
