Raba said: It is only necessary [to mention the corpse itself] for the case where there is the greater part  of the frame [of a corpse]  or the majority [of its bones],  which do not amount altogether to a quarter [kab] of bones. FOR AN OLIVE'S BULK OF [THE FLESH OF] A CORPSE, OR AN OLIVE'S BULK OF NEZEL: And what is NEZEL? The flesh of a corpse that has coagulated, and liquid secretion [from a corpse] that has been heated [and has congealed]. What are the circumstances? If it be not known to belong to [the corpse], what does it matter if it has coagulated?  Whilst if we know that it pertains to [the corpse], then even though it has not coagulated [it should defile]! — R. Jeremiah replied: [Secretion] of uncertain origin is referred to. If it coagulates, it is [cadaverous] secretion,  otherwise it may be phlegm or mucus. Abaye inquired of Rabbah: Is there [defilement through] corpse-dregs in the case of [defilement caused by] animals[' corpses], or not?  Was the tradition only that corpse-dregs coming from man [defile], but not corpse-dregs coming from animals, or is there no difference?  According to the opinion that the uncleanness is of the heavier type  only until [the animal is unfit to be eaten by]a stranger,  and is then of the lighter type  until [it is unfit to be eaten by] a dog,  there is no difficulty,  but according to the opinion that the uncleanness remains of the heavier type until [it is unfit to be eaten by] a dog, what answer can be given?  — Come and hear: If he melted [unclean fat] with fire, it remains unclean, but if in the sun,  it becomes clean. Now if you assume [that the animal remains unclean] until [it is unfit to be eaten by] a dog, then even if [the fat has been melted] in the sun, it should also [remain unclean]!  — It only melts after it has decomposed in the sun, and since it has decomposed it is [nothing but] dust. We have learnt elsewhere: Any jet of liquid [poured from a clean to an unclean vessel] is clean  save only [a jet of] thick honey  and heavy batter.
