1) 'And the Tzenu'os prepared a third Eid'.
(a) What does this mean?2)
(a) When does a bloodstain on her Eid have the Din of Vaday Tum'ah?3)
(a) Why do we not contend with the possibility that the bloodstain on the Eid is the blood of a louse, and is therefore no more that Safek Tamei? (two answers)4) If a woman examines herself with a cloth that she knows to be clean, wipes the cloth on her thigh, and then finds blood on her thigh, some quote Rava as saying that she is Vaday Temei'ah, and others, that she is only Safek Temei'ah.
(a) Which of these is the correct version, and what is the reason for this ruling?If she examined herself with a cloth not previously inspected, and the following day she discovered a bloodstain on the cloth, for many years, Rebbi Chiya believed that she was Temei'ah, but later in life he changed his opinion.
(b) What did he eventually hold?
(a) Since Rebbi holds in the previous case, that they are Tamei because of Nidah (like Rebbi Chiya's original contention), and not become of Kesem, how come that he agrees with Rebbi Chiya that the Shiur of the bloodstain must be the size of a Geris(which is normally the Shiur of a Kesem), and not just a drop even the size of the mustard-seed, which is normally the Shiur for Nidus?6) The Gemara concludes that Rebbi follows the reasoning of Rebbi Meir, whereas Rebbi Yossi follows his own reasoning.
(a) What is their Machlokes (a woman who was relieving herself)?7)
(a) Why does our Tana not mention that, in the case of Achar Osyum, they are obligated to bring an Asham Taluy?Our Mishnah writes 'Eizehu *Achar Zeman* Kedei she'Teired min ha'Mitah..... *ve'Achar-Kach* Metamei Mei'es Le'es.....Rebbi Akiva Omer' etc.
(b) How do Rav Chisda and Rav Ashi respectively, learn the corollary between 'Achar Zeman' and 'Achar Kach'?
