Indeed, we were able to ascertain the year of birth of three dead babies found in a deep-freezer to within 1-2 years (1986, 1988 and 2004, respectively), using the method. In spite of this evident success of the method there was one aspect of the **data** that represents a puzzle. The 14 C levels of the lenses were consistently smaller than those of the nails, corresponding to apparent later formation of the lenses (Figure 15). In fact the idea of combining (averaging) the 14 C **data** of nails and lenses is not supported by the data, i.e. the hypotheses that the nails and lenses are formed at the same time is less than 5% probable. Evidently, for a newborn baby the physical formation times cannot possibly differ by more than 9 months, during which the mother could however have changed her dietary preferences in terms of terrestrial/marine/petrochemical proportions leading to 14  content.
