Shabbat 108 - June 22, 30 Sivan

Some things are forbidden because it is considered removing it from its place of growth, including a fetus of an animal from the womb. Is a fetus considered a live being or not? What is the melacha that one is obligated for? Is the skin of a bird or fish considered skin? Can one write tefillin on parchment made from its skin? A story is told of the welcome that Rav received (not the most positive) when he arrived in Babylonia and was greeted first by Karna and quizzed and then by Shmuel. One can write tefillin on a kosher animal even if it was a treifa (sick) or died on its own. This was a subject of debate between a Baitusi and Rabbi Yehoshua the Garsi regarding the rabbinic traditions. Brine cannot be made on Shabbat as it is a tolada of ibud, processing. But can one prepare salt water for dipping one's bread? Taking medicine is problematic on Shabbat (in certain circumstances) lest one grind one's own medicines. However if one uses a medication that could also be used not as a medication and therefore it is not clear whether one is using it for medicinal purposes or not, it is allowed. In the context of salt water, the gemara asks regarding one who washes in the Dead Sea for medicinal purposes for one's eye. In what case would it be allowed? Other issues related to eye salves on Shabbat are discussed.
