Mishnah Negaim 14:10:He then takes from the Log [specific unit of volume] of oil and pours some on the palm of his friend [the other priest]. If he poured it into his own palm it is valid. He dips [his finger in the oil] and sprinkles seven times towards the Holy of Holies and before every sprinkling there was a dipping. He then came to the leper and wherever he placed the blood, there he places the oil, as it says (Leviticus 14) "On the place of the blood of the guilt-offering. What remains from the oil in the palm of the priest he should place on the head of the person being purified to atone." If he placed it he atones, if not he does not atone, says Rabbi Akiva. Rabbi Yochanan ben Nuri says, they are the leftover of a commandment and regardless of whether he places it or he does not place it he atones but we consider him as if he did not atone. If part of the Log was deficient before he poured it, he must refill it, once he pours it out he must bring another as in the beginning, says Rabbi Akiva. Rabbi Shimon says, if the Log was deficient before he placed it he must refill it, once he placed it he must bring another as in the beginning.

Mishnah Negaim 14:11: A leper who brought his sacrifices while poor and then became rich, or while rich and then became poor, everything goes after the sin-offering, says Rabbi Shimon. Rabbi Yehuda says it goes after the guilt-offering.
