Zevahim 77: Mixed-up Limbs

Two new mishnayot for today's episode (and one for tomorrow's): 1. What happens if the limbs of already slaughtered animals for different offerings are mixed up? With several possible solutions to the mix-up to ensure that nothing is violating the honor and sanctity of the altar. 2. What if the limbs of a valid offering are mixed with the limbs of a blemished offering? And again, with assessment in the Gemara as to how to handle them.
