The fact that dividing cells are usually only found in actively growing tissues does not necessarily prove that growth and cell-division are two closely correlated phenomena. Growth may be defined as an increase in the amount of organised material which is present in the cell and which is essentially part of the living machine. Cell-division, on the other hand, only implies the cleavage of the cell into two or more parts. The purpose of this work is to enquire into the relationship between the two phenomena when they are taking place together. The material used was the segmenting eggs of Echinus miliaris.
