Description :
A linear regression between lens weight and age was found in 24 dormice aged 1.5 to 6.0 months. The estimaded value of the lens weight was given by the following equation Y = 27, 448 X + 70, 801. The upper and lower limits of the confidence intervals were calculated. The age of 41 wild dormice was estimated by the inverse prediction method of Sokal and Rohlf (1969). The estimated age thus established was in agreement with estimates based on other morphological and behavioural criteria. Hibernation apparently slows down the increase in weight of the eye lens in field conditions.
