One who set down an issar and ate against half [of it], then went to another place where it can be spent as a pundeyon, may eat another issar against it. One who set down a pundeyon and ate against half of it, then went to another place where it can [only] be spent as an issar, may eat another half against it.  One who set down an issar of maaser sheni may eat eleven per issar against it, and one from a hundred per issar. Beis Shammai say: It all is ten. But Beis Hillel say: In definite [maaser sheni], eleven; but in demai, ten.
