R' Chanina, administrator of the Kohanim, said: In all my days, I never saw a hide being taken out to the place of burning. R' Akiva said: From [R' Chanina's] words we learn that if one skins a bechor and it is [then] found to be a te-reifah, then the Koha-nim may benefit from its hide. But the Sages say: “We have not seen” is not a proof. Rather, it goes out to the place of burning.

He also testified about a small village that was adjacent to Jerusalem, and there was in [this village] a certain sage who and he would lend [money] to all the villagers, and he would write in his own hand and others signed.  When the incident came before the Sages, they permitted it. [And from this testimony] you may learn incidentally that a woman may write her own get, and a man may write his own receipt, be-cause the validation of a document is [effected] only by its signers.  And [R' Chanina testified] concerning a needle that was discovered in the flesh, that the knife and the hands are tahor but the flesh is tamei. And if [the needle] was discovered in the excrement, everything is tahor.
