A tiny page of Gemara on amud left, with a massive amount of commentary by the Baalei HaTosafot - on the red heifer, and a parallel discussion from the tractate Hullin. Specifically, on whether the meat of kodshim and dough can join together to form a minimum measure (spoiler: they do not). Also, more on the slaughtering that takes place with the animal that has been stolen.... and how an animal that has been improperly slaughtered can be accounted for.
