Reply To: Why is Lavud Part of the HL"M of M'chitzin?

A big question dealt with by the Acharonim on this Amud is why the list of Mechitzin agreed to by all Shitos is missing Shelishis Afilu Tefach, which Rashi DH Hilchesa clearly writes is part of it as well. I suggest that it is because the list is comprised only of those Halachos l’Moshe mi’Sinai related to Mechitzin that we have dealt with thus far in the Masechta. If this is so, then the original question is answered as well.
