Abstract
FOLLOWING Schaefer's cloud-chamber experiments1 on the formation of ice crystals in supercooled water-droplet clouds by localized cooling, Langmuir has noted the possibilities of producing ice-crystal clouds on a large scale, and has observed the sudden formation of a veil of ice-crystals 600 ft. below a seeded cloud, caused by the passage of ‘dry ice’ pellets2.
