摘要：

1. Intra-abdominal temperature of 13 normal and 13 tau-mutant golden hamsters maintained in constant light at 22-degrees-C was recorded by telemetry. Data for 10 days of continuous recording were analysed for the four parameters of the circadian rhythm of body temperature (CRT): period, amplitude, mean level and shape. 2. The mean period of the CRT was significantly shorter in tau mutant hamsters (20.2 h) as compared to normal hamsters (24.0 h). No significant difference between the two groups was found in the other three parameters. 3. It is concluded that the tau mutation has a specific effect on the period of the CRT without affecting the other parameters of the rhythm.
