A new mishnah! If you buy the "fruits" of a dovecoat, or of a beehive, or even honeycomb, then the "first fruits" of each of them need to be left for the seller to bring in offering. The mishnah specifies what measure of each is necessary. Also, if you buy the honeycombs of a beehive, you need to leave 2 of them behind for the bees. Plus, a discourse on the unique properties of honey as food -- that comes from a non-kosher animal, no less -- as well as a discussion of the nature of the beehive as a kind of property.

Two new mishnayot! First - When it comes to selling a donkey, what gear, if any, is included as a default? The answer may depend on whether donkeys were primarily used for riding or as pack animals. Second - second other animals... Plus, the question of selling a donkey with its foal (vs. a cow with its calf).

Indebtedness, and how transfer happens. Plus, when and how one can rescind with regard to the given transaction. Also, how movable property is acquired together with land. Plus, how a sale can be effected even via the transfer of a document, depending on the connection with land. Plus, defining "antiki" and why it's not part of a default sale if not stipulated. And... a new mishhnah! When one makes an offer for an item, what things are NOT included with that attempt to purchase? Sometimes, the sum that is offered reveals the thinking of the purchaser, but the sages say that may not matter.

How do you acquire a boat? It's a debate between Rav and Shmuel, even after they try to draw the parallel to the acquisition of a large animal and the "pulling" that is effective in that case. In this context, Rabbi Natan raises the discussion of letters - and the Gemara fills in the details about documentation in the transfer of ship ownership. Also, what are the details that are essential for transfer of ownership to take place? Is a document enough? Is a transfer of a document enough? A dispute between Rabbi Yehudah HaNasi and the sages.

More on the Leviathan. Among other details, the Leviathan can boil the water of the ocean. Also, it's very smelly. Also, -- all of which details have prooftexts, especially from the Book of Job, to back them up. Plus, a discussion of glory of the Leviathan and its benefits for the righteous. [Where's Where: Tzipori] Plus, a description of Jerusalem as part of the World to Come. Also, back to halakhah... Buying a ship, which is a "movable" item - which requires a formal proprietary act of acquisition. How far would one need to move it for that movement to count as your taking possession of the ship?

More of the dramatic, fantastical, fascinating passages. Rabbi Eliezer and Rabbi Yehoshua traveled by ship - and they see a great light in the sea, which opens up a discussion about the Leviathan. Likewise, another trip, this time with apparent magic happening to the meat from which they had cut out the sciatic nerve, and the apparent magic that happens on that spot even a year later. Also, a deep focus on the Leviathan, male and female, as well as its placement in this chapter of Bava Batra.

Chapter 5! A new mishnah -- with a shift to a discussion of movable property, and what is included in their sales. For example, what is included in the sale of a ship (when the formality does not stipulate: "and everything that is within it"). Also, the voyages of Rabbah bar bar Chana -- which go beyond a traveler's account to mystical teachings/ experiences.
