Eduyos 2:4

Rabbi Yishmael said three things in front the Sages in Kerem b’Yavneh: (1) a beaten egg on a trumah vegetable is considered connected unless it has an empty air space like a hat; (2) if the top of a stalk of unharvested grain reaches the standing grain, then if it can be harvested with the standing grain, it belongs to the owner, otherwise it goes to the needy; (3) regarding a small garden that is surrounded by vines on trellises, if there is enough room for a grape-picker with a basket on each side, then one may plant there, otherwise not.

Eduyos 2:5

Three things were stated in front of Rabbi Yishmael, which he didn’t rule prohibited or permitted. Rabbi Yehoshua ben Masya explained them: (1) opening an abscess on Shabbos renders one liable if his intention was to make an opening but one is exempt if his intention was to remove the pus; (2) a person who catches a snake on Shabbos is exempt if his reason was to keep it from biting him, but he is liable if he wanted the snake for use in a medication; (3) "Ironian" cooking pots (i.e., sealed spheres that have not yet been opened) are ritually clean when under the same roof as a corpse but they are rendered unclean when carried by a zav. Rabbi Eleazar ben Tzadok says they remain ritually clean even when they are carried by a zav because their construction has not yet been completed.
