A new mishnah - from the bottom of daf 78: What happens to the thanksgiving offering when there's an issue with the grain-offering part of it -- as compared to the animal part of it? Plus, the connection to the inauguration of Aaron and his sons as kohanim. With a focus on a dispute revolving around a blemished animal vs. the incorrect location for slaughtering, as issues that interfere. But is that even the right comparison? Plus, cataracts as the blemishes. Also, another mishnah: animal offerings together with libations - and the question of these accompaniments being problematic for whichever reason, and how they are left overnight to disqualify them. Note that replacement animals are sacrificed as well, just not as a thanksgiving sacrifice - once they've been designated to replace a korban todah.
