The National Geographic Society has announced the organization of a scientific expedition to study high altitude cosmic‐ray effects over twenty‐three degrees of latitude in the mountains of India. Martin A. Pomerantz, research physicist at the Franklin Institute's Bartol Research Foundation, will head the party. Dr. Pomerantz is expected to arrive in Bombay this month after having spent several weeks consulting with colleagues in London, Paris, and Amsterdam. He will be joined in Aligarh by a group of Indian scientists, including P. S. Gill, director of the department of physics at Muslim University, who will participate in the study.
