Rabbi Yitzchak Isaac inquires in this letter as to whether Rabbi Menachem Manish has received his books. He writes that he has received responses from his brother Rabbi Alexander Sender and from the rabbi of Tarnopol. He also apologizes for not answering the letter from his son, Rabbi Ephraim Zalman Margaliot, because he received a responsum from the author of Ketzot HaChoshen [this responsum was printed in his book]. The letter is signed: Yavi”tz S”T, as he signed several times in his responsum which was printed in the responsa by Rabbi Meshulam Eiger [more material is enclosed with this lot].
