bute certain information received from James Angleton, CIA, under
the symbol "Bureau Informant 100." This information, for the most

the Israeli Intelligence Service and from other sources under the
control of Angleton. Much of the information developed by Angleton

passed on to the Bureau. Allen Dulles gave him authorization to
handle dissemination in this matter. We continue to receive informa-

offices have had rare occasion to receive Bureau Informant 100 infor-
