Abstract
In the study of the metabolic rate of Amphibia, a careful investigation has been completed for the Californian newt, Triturus torosus. Groups and single individuals have been measured at numerous intervals. The data cover the range of life history from time of early cleavage stages until time of sexual maturity. The metabolic rate is expressed in cubic millimeters of oxygen consumed per milligram of total nitrogen content of the animal per hour. The total nitrogen content of the animal was found to be a better basis of reference rather than surface area or dry weight. The oxygen consumption was measured by use of Barcroft-Warburg manometers. Total nitrogen content was determined by the improved micro-Kjeldahl method of Cavett with minor modifications.
