The non-quadratic behaviour of the specific-heat enhancement below 5 K 
as measured by Novoty, Meincke, and Watson for 22   lead particles
[ Phys. Rev.Lett. 28, 901 ( 1972 )] is explained by rigorously summing
the contributions of all the 183 vibrational modes of the respective free
sphere problem. In addition a maximum of the enhancement is predicted
near 8 K. The usual asymptotic surface term fails. The mean squared
frequency < omega^2 > is calculated.
