I, the undersigned Ian Donald of the above address and formerly  Regius Professor of Midwifery at Glasgow University from 1954 until 1976 and thereafter Honorary Obstetrician at the Western General Hospital Edinburgh until 1981 and Honorary Research Consultant at the National Maternity Hospital Dublin, having had experience in the development and exploitation of Diagnostic Ultrasound, particularly in Obstetrics from 1955 onwards until 1981, the last four years of which were much taken up with filming fetal activity at various stages of pregnancy, particularly the first half thereof, have now studied Dr. Nathanson’s video-tape film entitled “The Silent Scream” not less than four times and affirm that I am of the opinion that the fetal activities depicted by ultrasonic real-time scanning in this film are not faked nor the result of artifact intentional or otherwise.
