Bela Varga, vice-premier of Hungary until 1947, will speak at the Law School Forum on "The Satellite Revolts: Their Meaning" at 8 p.m. this evening in Sanders Theater.

Leon Volkov, a former colonel in the Soviet air force, Marek St. Korowicz, former Polish delegate to the United Nations, Leslie Tater, Hungarian television writer, and Stoyan Gavritovitch, former Yugoslav undersecretary of state, will also be on the program.

A discussion of the satellite problem on a larger scale will take place at 8 p.m. on Sunday at a rally in Mechanics Hall, sponsored by the New England Committee of the International Rescue Committee, protesting the Russian slaughter of Hungarians. Among the speakers at this meeting will be Anna Kethly, the only member of the Imre Nagy government to leave Hungary.

Dr. Albert Szent-Gyorgi, Hungarian-born Nobel Prize winner, will also be present at the rally. Szent-Gyorgi relayed an appeal on Sunday to American university students from his former colleagues at the University of Szeged, who asked for aid for Hungarian students. The Student Council unanimously lent support to the Hungarian students on Monday night in response to Szent-Gyorgi's plea.

Others at this protest gathering include Leo Cherne, chairman of the International Rescue Committee, who arrived last Saturday from Budapest, and former Ambassador Angier Biddle Duke, committee president, who flew from Austria Wednesday. Admiral Richard E. Byrd, honorary chairman, and General William Donovan, chairman of the national committee, will also speak.
