He cites an experiment with an infant Of 9 kg, who was in the chamber for one hour and ten minutes, and gives protocols for another experiment, one hour in length, presumably with the same infant. In summing up his averages he refers to numerous experiments on infants weighing from 6 to 9 kg, and includes Observations made with environmental temperatures rang ing from 18 C. To 25 C. He concludes that the infant produces on the average 4 calories per kilogram of body - weight per hour. Richet dis cusses especially the relationship between the body - surface and the heat-production. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
