was counted as a single REGENERATION IN AN EARTHWORM 433 and a terminal in which fragments do not regenerate at all. For that portion of the axis in front of 30/31 we are still dependent upon the data of Morgan's experiments discussed in the notes to Table III.

Regeneration of earthworm populations has contributed partially to the improvement in soil chemical and physical properties and an increase in litter decomposition rate.
