[If] a seah of terumah fell into less than one hundred, creating a meduma mixture, and [then a portion] fell from the meduma mixture to another place, R' Eliezer says: It makes the [new] mixture meduma just as definite teru- mah would. But the Sages say: A meduma mix-ture does not make another mixture meduma except in proportion [to its terumah content]; and [a batch of dough] that was leavened [with terumah] does not render [another dough] leavened [with terumah] except in proportion [to its terumah content]; and drawn water does not disqualify a ritual bath except according to proportion.

[If] a seah of terumah fell into one hundred, [and] he lifted it out and another fell [in], [and] he lifted it [out] and another fell [in], it is permitted, until the terumah exceeds the chullin.

[If] a seah of terumah fell into one hundred [seahs of chullin], and he did not manage to lift it out until another fell [in], it is forbidden. But R' Shimon permits.

[If] a seah of terumah fell into one hundred [seahs of chullin], and he then milled them and they diminished, just as the chullin diminished, so did the terumah diminish, and it is permitted.  [If] a seah of terumah fell into less than one hundred [seahs of chullin], and he milled them [together], and they increased, just as the chullin increased so did the terumah increase, and it is forbidden. [But] if it is known that the chullin wheat is of a higher grade than that of the terumah, it is permitted. [If] a seah of terumah fell into less than one hundred [seahs of chullin], and afterwards [more] chullin fell there, if it was inadvertent, it is permitted; but if it was intentional, it is forbidden.
