(c) What did other Rabbanan used to do when going down to the river to Tovel, and when returning?
(a) Why is it forbidden to touch the Mekom ha'Milah?
(b) Why might it possibly be permitted to do so when going to Tovel in a river?
(c) The Gemara proves this from the Mishnah of 'Baleshes ha'Nichnas la'Ir'. What does the Mishnah say there, and what is the proof from there for our case?
(a) Which useful tips (concerning Tevilah) did Rebbi Zeira learn from Rav Yehudah before leaving Bavel for Eretz Yisrael?
(b) How did Rebbi Zeira interpret the Pasuk in Yirmiyah "Bavelah Yavo'u, ve'Sham Yih'yu"?
(a) About what does the Beraisa say ...
1. ... 'Achilaso Dam, ve'Zehu Techilas Choli Me'ayim?

(b) Which three things does the Tana advise someone who bathes in hot water to do?

1. ... 'Bei Kiri'? Why is its Din stricter than a Muliar?
2. ... 'Bei Dudi'? Why is its Din stricter than a Muliar?
(b) The Gemara corroborates the opinion of Rav Nachman bar Yitzchak from a Beraisa, which gives the reason for the prohibition to drink from it 'Mipnei she'Nechushtah Mechamemasah'. What does 'Nechushtah' mean?
(c) According to Rashi's Rebbes a Muliar is an urn with the coal section underneath. Then what generally makes an Antichi more stringent than a Muliar?

(a) The Mishnah writes 'ha'Meicham she'Pinehu, Lo Yiten le'Tocho Tzonan Bishvil she'Yechamu'. How does Rav Ada bar Masna explain this?
(a) What is 'Metzaref', and why is it Asur on Shabbos?
(b) Why, according to Rav Ada bar Masna, if someone pours a little cold water into a boiling hot pot on Shabbos, has one not transgressed the Melachah of Metzaref?
(a) What is Abaye's objection to Rav Ada bar Masna's explanation of the Mishnah - 'ha'Meicham she'Pinehu?
(b) So how does Abaye interpret the Mishnah?
(c) Who will now be the author of our Mishnah, which forbids one to pour cold water into a boiling pot that has been emptied?

(c) What does Shmuel say?
(d) What is now the basis of their Machlokes?
