PER CURIAM:
The order granting a rehearing en banc, 608 F.2d 238, is vacated as having been improvidently granted on the record before us, and the panel opinion, 598 F.2d 994, is reinstated.
[2] GEE, Circuit Judge, with whom BROWN, CHARLES CLARK, TJOFLAT, FAY, REAVLEY, POLITZ, ANDERSON, RANDALL, TATE, SAM D. JOHNSON, and THOMAS A. CLARK, Circuit Judges, join, specially concurring.
I concur in the court's order because no proffer was made of evidence tending to show advances in the state of polygraph art since the seminal opinion in Frye v. United States, 293 F. 1013 (D.C. Cir. 1923), upon which our authorities are based, or the competence of polygraphic operators. Had one been made, in my view these authorities would properly be subject to reconsideration.
