1. 1. The body temperature of seven tortoises, Geochelone pardalis, was measured in a thermal gradient chamber, by indwelling thermocouples, after injection of various pyrogens. 2. 2. The tortoises regulated their body temperature by moving in the chamber. 3. 3. The tortoises did not develop fever in response to any of the pyrogens we tested. 4. 4. The results support the contention that fever in reptiles is not ubiquitous.
