Bekhorot 23: A Meta-Discussion on a Mishnah's Structure

Coming in the middle of a long discussion with a focus on a mix of sacred and regular ashes -- where impurity would be nullified via the mixture. Also, a new mishnah! If one purchases an animal from a non-Jew, and it is nursing, we don't worry that the nursing animal had a different mother. Which leads into a discussion about the opinions represented in the mishnah here, in terms of anonymity.
