C. We should like, especially, to express our appreciation to Frederick Silkworth for the chemical separation of chlorine from many kilograms of rock during the course of the work we have described. Nathaniel Arbiter generously allowed us to use the crushing and grinding equipment in his laboratory at Columbia University. We should like to acknowledge also the helpful discussions concerning cosmic ray neutrons with Henry Kraybill and William Ortel of Yale University, New Haven, Conn. We are indebted to R. S. Preston and N. R. Whetten of the Yale Cosmic Ray Group for collecting the sample of phonolite from Cripple Creek, Colo. The electronics department of this laboratory was most helpful in construction of the anticoincidence counters and associated circuits.
