One of the less practical elements of the Talmud, in lining up opinions that have already been authorized... Specifically R. Meir, in this case. Also, a recommendation for Point by Point Daf (dafyomi.co.il) - for outlines. What's What: Pigul. Notar. Also, moldy food and its relation to the tumah status (which can't be applied to something that is so far gone it's not food). The role of the dog in determining what counts as food is reminiscent of how we determine what is food with regard to chametz too. Also: A barrel of wine that is consecrated as terumah, which is pure, in a wine press, above the unconsecrated impure wine. What is the upper spills into the lower and they mingle?! The discussion reminds us that there's no value judgement for the status of tumah - it's not better than tahor, it just is. Another quick What's What: The measurement, Log.
