Basal metabolism tests and the physical character studies have been carried out in 32 young men at Hyderabad (Deccan). The ages varied from 19 - 31 years, the average being 22 years. No difference was found in the pulse and the respiration rates as compared with the western standards. These subjects were found to have somewhat (1.2 cm.) shorter stem height and correspondingly longer legs compared to the measurements obtained on the Westerners. A pelidisi of about 92 indicates the normal state of nutrition in young Indians, the average pelidisi for 30 out of the 32 subjects being 92 -4. The blood pressure was found to be considerably lower compared to the western standards. The average systolic blood pressure in 30 out of the 32 subjects was 100.4 ± 11 mm., the average diastolic pressure 71.8 ± 5mm., and the average pulse pressure 28.6 ± 7.2. The basal metabolism was found to be 6.8 per cent below the Harris- Benedict and 8.7 per cent below the Aub-DuBois standards. The factors which may tend to bring about this low level of metabolism are discussed. The possibility of the humid climate being a factor in lowering metabolism is suggested. Eight of the subjects who were vegetarians showed the basal metabolism on an average about two per cent lower than that obtained for the whole mixed group. For height and age, the weight in this group of subjects was less than the American standards.
