Students at Brandeis University quietly demonstrated against a $250 tuition increase yesterday afternoon. The Student Council called the gathering of about 150 students "mature and responsible" and said it was made not only to protest the tuition raise but also to demand a chance to talk with officials.

Dissatisfaction arose among the students Monday night when John R. Roche, dean of the faculty, and Joseph F. Kauffman reportedly walked out from a student-faculty question period.

Myra Saft, vice-president of the Student Council, last night issued the Council's statement, which said the group "supports the intent of the demonstration" and "protests and opposes" increasing tuition after the administration had promised to consult the student body before doing so.

President Abram L. Sachar said that he is still willing to talk to students, according to Miss Saft.
