This is probably the last in the series. A lot of good stuff from Rav Tzuriel shlita. As noted by Meir, the correspondence between the disappearance of shedim and the extinction of bas kol is suggested in the Emes l'Yaakov.

People Of The Book: Classic Works Of The Jewish Tradition
By Dr. Henry Abramson
Two hundred years ago, Sefer HaBrit was a fixture in the library of every educated Jewish home. First published anonymously in 1797, this hugely popular 800-page tome appeared in 40 editions, including translations into Ladino and Yiddish. It was widely read by Ashkenazim and Sephardim, western and eastern European Jews, chassidim, mitnagdim, and maskilim with equal enthusiasm.
