“A new method of studying metabolism”

Abstract

The author described experiments then in progress upon metaolism in unicellular animal organisms. These forms, reproducing by simple division, offer the same protoplasm for study generation after generation, and with each division the daughter organisms, by reason of the functions of regulation and regeneration, perfect themselves in the race-type, while digestion, assimilation, waste, repair and growth are handed down unchanged from cell to cell.
