Abstract
IN the course of our investigation on the respiratory regulation in man at high altitudes in the Himalayas1 it was observed that the respiratory response of the Indian subject to carbon dioxide was lower than the European2. The unit of carbon dioxide response (pulmonary ventilation, 1/min/mm mercury) is such that it should ultimately be related to the metabolic rate or the body weight. The body weight of the Indian subject was smaller (56 kg), and it was thought that his apparently low response to carbon dioxide may have been caused by his lower body weight.
