Experiments have been performed on the bonding of polished and microtomed ice surfaces at -5C. These surfaces showed an appreciable curvature and unevenness. The force of separation after bonding for 60 min under different weights increased with weight. The surfaces placed together immediately after preparation showed an appreciably higher force of separation than those placed together after a time interval. The force of separation for surfaces placed together at zero humidity showed a higher force of separation than those placed together in an atmosphere of 100% relative humidity. A preliminary simplified theory of bonding of irregular surfaces has been developed. Previously announced as PB159278.
