Tosefta על תרומות 2:6

A seah of terumah that fell into one hundred [of chullin] and afterwards [the entire mixture] fell into [a second batch of] chullin of any amount, behold, it is permitted. A seah of terumah [wheat] that fell into one hundred [of chullin wheat], we do not subtract the zunim (an inedible type of wheat that grows among regular wheat) that is in it (i.e., it may count toward the one hundred). A log of clear wine that fell into one hundred logs of cloudy (i.e., unfiltered) wine, we do not subtract the sediment that is in it (i.e., in the cloudy wine). A log of cloudy wine that fell into into one hundred logs of clear [wine], we do not subtract the sediment that is in it (but see Yerushalmi, holding that it is subtracted in this case).
