Yevamot

they must all be burned;  so R. Meir. The Sages, however, stated: They are neutralized in [a mixture of] two hundred and one.  R. Meir, [in his ruling,] is of the opinion that whatever  might be counted causes forfeiture,  while the Sages are of the opinion that only six things cause forfeiture.  R. Akiba said: Seven. They are the following: Crack-nuts,  the pomegranates of Badan,  sealed jugs [of wine], young shoots of beet,  cabbage roots and the Grecian gourd. R. Akiba adds also home made  bread.  Those which are subject to the law of 'orlah  [impart the prohibition of] 'orlah  [and those which are subject] to the law of kil'ayim of the vineyard  [impart  that of the] kil'ayim of the vineyard.  R. Johanan holds the view that the reading  was, 'That which one is wont to count'  while Resh Lakish holds the view that the reading was 'Whatsoever one is wont to count'. What [is the Baraitha about the] piece?  — It was taught: A piece of a levitically unclean sin-offering that was mixed up with a hundred pieces of clean sin-offerings and, similarly, a piece of levitically unclean shewbread  that was mixed up with a hundred pieces of clean shewbread is neutralized.  R. Judah said: It is not neutralized.  If, however, a piece of a levitically clean sin offering was mixed up with a hundred pieces of clean and unconsecrated meat, and similarly if a piece of levitically clean shewbread was mixed up with a hundred pieces of clean unconsecrated bread, all agree that neutralization cannot take place.  Now in the first clause, at any rate, it was stated that it 'is neutralized'!  — R. Hiyya son of R. Huna replied: In [the case where it was] crushed.  If so,  what is R. Judah's reason?
