 Due to the BBCs policy of junking episodes in the 1970s, this  episode no longer exists in the archives. Several clips survive in  the form of an 8mm home movie reel shot off a television set. They  are: four seconds of Barbara in her cell talking to the Doctor about  regretting having taken Susan to see the physician; three seconds of  Barbara remarking on the Doctors Regional Officer of the Provinces  disguise; one second of Ian talking in the surgery; two different  one second shots of the Doctor talking; and one second of Ian and  Barbara in Jules house, surprised by Lemaitres entrance. These  clips are included on the "Doctor Who: Lost in Time" DVD box set  released in 2004.
