Kiddushin 54: The Holy Stones of Jerusalem

More on what can and cannot be used for betrothal, specifically among the sanctified property, specifically the garments of the kohanim - that have not worn out. And what about the worn out garments? When does me'ilah (misuse of consecrated property) kick in? Also, the question of whether the walls of Jerusalem are consecrated, and if so, does that mean stones loose from the wall are subject to me'ilah? With more dispute between R. Meir and R. Yehudah.
