There (in Bavel), they say that one who wants to refrain from relations, he eats half [of Tzipores Keramim] and leaves half. The left half is forbidden (it is dangerous), and the right half is permitted.

If [he ate the right half], and any amount [of the left half] was lost, or any amount is missing, he has no solution (he will forget his learning).

Question: What should he do [so none will get lost]?

Answer (R. Yosi bei R. Bun): He puts it in a plate of honey. (This preserves it. We find that Hurdus preserved a dead girl for seven years in honey (Bava Basra 3b) - B'SHULEI GILYONI.)

Note: Some permit Isur that fell into honey, for it dissolves and becomes honey (brought in YD 84:12). To resolve this with the case of Hurdus, Rashba (Teshuvah 1:80) says that this is for what is cut, but honey preserves whole things. Perhaps Tzipores Keramim is different, and even half of it is preserved in honey.

(Mishnah - R. Yehudah): Even one who is Motzi a live Tamei grasshopper of any size.

Inference: If it is Tahor, whether it is live or dead, the Shi'ur is k'Grogeres. (We do not say that he is liable for a live grasshopper of any size, for a child plays with it!)

Explanation: R. Yehudah teaches like he taught elsewhere. R. Yehudah taught that one does not play with Tahor food.

Question: It says [about Livyasan] "ha'Tischak Bo ka'Tzipor''! (Surely it is Tahor, for in the future Tzadikim will eat from it!)

Answer: Is it not [forbidden], just the Isur will be permitted?!

Question: It says "ka'Tzipor''! (This shows that one may play with a bird. Tzipor connotes a Tahor bird.)

Answer (R. Matanyah): Since it is lacking (forbidden until) Shechitah, it is like a Tamei [species].
