Hanatziv's (?) Eulogy in Memory of the Rada"l

Manuscript. Halachic and Aggadic homiletics with appreciation words and facts about the Rada"l's life, by the Natzi"v(?).
Autographic writing with many additions and deletions. Written about a month after the Rada"l passed away on 5th of Kislev, by the person who delivered the speech in public on 10th of Tevet.
It is not absolutely clear to us who the writer was. The writer mentions having received halachic responsa from the Radal and notes the "disagreement in our city" as well as quotes his "Father in law".
It is possible to assume by the contents of the letter that the handwriting is of Rosh Yeshivat Volozhin, Hanatziv, who was supported and encouraged by the Radal during the days of disagreement in the Yeshivah.
Rabbi David Lurie – Radal (1798-1855, Otzar Ha-Rabanim 4890), an outstanding genius in his generation. Was born on the year that The Vilna Gaon died, and was considered his foremost disciple of disciples. Due to his genius he was awarded the responsibility for printing The Vilna Gaon's writings. Radal composed many essays, halachic responsum. Glosses and commentaries on the Babylonian and Jerusalemite Talmud, Midrashim and the Zohar.
