2 small mishnayot: 1. On vessels of wood and metal, how they each have that which is stringent and that which is lenient, as compared to the other. 2. On bitter almonds and sweet almonds, how they each have that which is obligated in the one and exempt in the other, and vice versa. Note the two different kinds of almond trees. And note that roasting almonds counteracts the cyanide at its core. Also, on "Temed" - an fermented ersatz grape juice that is not initially eligible for purchase with ma'aser sheni money -- and it would invalidate a mikveh -- until it's truly fermented. Plus, orphan brothers who are exempt from tithing their animals, but need to separate them nonetheless.
