1) If a woman finds on her vest, a bloodstain of more than a ki'Geris, plus a louse squashed on it, Rebbi Chanina holds that she is Temei'ah.
(a) Why is that?A woman who is dealing with a ki'Geris volume of the blood of a bird, finds more than a ki'Geris.
(c) Why might Rebbi Chanina agree that she is Tehorah, and why might Rebbi Yanai agree that she is Temei'ah?The Beraisa says that a woman who was dealing with red blood and discovers black blood-stains on her garment, or one who was working with a small quantity of blood, and finds a large quantity, cannot connect the stains to the blood she was working with, and she is Temeiah.
(d) Now if this does not come to issue a ruling in the case quoted in (c), then what *does* it come to teach us - and what will be the Chidush?2) Rava says that, if a woman finds a stain on her garment, she can later connect other stains to the one that she found.
(a) What does he mean?3) Our Mishnah quotes the story of Rebbi Akiva, who issued a lenient ruling to the woman who had a wound that was healing.
(a) How do we reconcile this with the Beraisa, which says that the Chachamim do not come to be lenient, only to be strict?Rebbi Eliezer b'Rebbi Tzadok rules that an elongated stain on the woman's Eid is Tamei, whereas a round one is Tahor. The Gemara asks whether the Rabbanan argue with him or not.
(b) What proof does the Gemara attempt to bring from the Beraisa, which says that an elongated stain will combine to make up a ki'Geris plus?
4) Our Mishnah differentiates between a woman who sees blood whilst urinating standing and urinating sitting.
(a) Why do we not suspect, even by a woman who urinated sitting, that maybe the urine flowed back and brought with it blood from the Mekor (like we do when she urinated standing)?If a man and a woman both urinated into one bowl, Rebbi Yossi will certainly be Metaher, because it is a double-Safek.
(d) What does Rebbi Shimon (who obviously follows the opinion of Rebbi Meir in the Reisha) hold in this case, and why?5) Resh Lakish maintains that, according to Rebbi Meir, who is strict as regards blood found in a bowl into which a woman had urinated (the Reisha of the Mishnah), the Din will be the same if a man had also urinated into the same bowl, and there is a double-Safek.
(a) How does he know that?Rebbi Yochanan disagrees with Resh Lakish.
(c) What, in his opinion, does Rebbi Meir hold in the Seifa?6) Rebbi Shimon in our Mishnah is strict even if a man, as well as a woman, urinated into the bowl.
(a) What does Rebbi Shimon hold in the Reisha of our Mishnah, when the woman alone urinated into the bowl whilst sitting?7)
(a) What will be the Din, if a woman lends her vest to a non-Jewish woman or to a Jewish woman who is a Nidah, and then, after she gets it back, she wears it and discovers a bloodstain?
