A comprehensive survey of the esoteric mysteries of the field if cryogenics was arranged by Dick Strobridge. Enormously valuable papers were presented by Hurlich of General Dynamics and Mowers of Rocketdyne on the properties of materials at low temperatures; these papers will save many of us from making costly and dangerous mistakes. Papers on refrigeration and cryostat design provided a fine survey of the state of the art and of the directions in which further progress can be expected.
