P.127 left column bottom paragraph: "The material collected was fixed at different places in the world. Therefore the shrinkage of the single specimen
is not reliably determined. According to [investigators’] experience, [they] must expect that the sizes estimated in a
specimen may deviate from the actual size of the species investigated. The differences, however, are surely small,
as shown by the estimation of the variance in man. The variability in man is about 15-20% above and below the
mean values (primary sources). The differences between the animals of various families
are in the magnitude of a power of four. Therefore, [they] feel that a comparison is allowable. This point will be
discussed after the report of the results." |
