What was the function of the quarter [-log]? A quarter [-log] of water for the metzora and a quarter [-log] of oil for the nazir. What was the function of the half-log? A half-log of water for a sotah and a half-log of oil for the todah-offering. They measured all minchah-offerings with the log. Even for a minchah-offering of sixty issaron, one supplies for them sixty log. R’ Eliezer ben Yaakov says: Even a minchah-offering of sixty issaron contains only its one log; as it is stated (Lev. 14:21): for a minchah-offering, and a log of oil. Six for the bull, four for the ram, three for the lamb, and three and a half for the menorah; [on the basis of] half a log for each lamp.
