In a previous publication (1) the author described experiments in which the “overshoot phenomenon” reported by Silsbee, Scott and Brickwedde (2) might have been expected but was not observed. The specimens used were straight wires mounted so as to be completely surrounded by the liquid helium bath. Silsbee and his co-workers used wires coiled on paper or glass cylinders. It was concluded that the “overshoot phenomenon” was due to this method of mounting the specimen and was therefore a secondary effect.
