Restoration began during the latter part of the first day following the removal of 70% of the liver, and the preoperative ratio of the liver weight to the body weight was essentially restored from the tenth to the fourteenth day. The more rapid rate of restoration took place during the third and forth days. Since transient loss of body weight ensued on operation and was not essentially recovered until from twenty-five to twenty-eight days, hepatic restoration was determined as complete at this time.
