Abstract
A VERY valuable summary of modern views on this difficult subject will be found in two little monographs by Prof. A. Guilliermond of the Sorbonne, dealing respectively with the ‘chondriome’ and ‘vacuome’. These two names are given by the author to two distinct types of morphological unit which can be found in varying form in the cytoplasm throughout the life of the cell. The cytoplasm itself is regarded as an optically empty colloidal solution of long colloidal thread molecules (proteins, etc.), which have imbibed so much water that their refractive index approximates to their aqueous medium. They thus give the properties of a viscous sol to the cytoplasm, but the thread molecules link up at any surface to form an elastic solid plasma membrane.
