The nerve cord from post- clitellar segments 14-22 was pulled, in normal orientation, into these anterior segments by the use of silk thread and a long needle. The first four head segments, including the nervous organs, were discarded. At the end of two and one-half months the worm was fixed. A new head with brain, commissures, and oral opening is evident. Three segments and a prostomium are new. The brain lies in the third new segment. In Case 103, the removal of the anterior nerve cord from segments.
