astids issurrounded by a semipermeable membrane which retains ^ Czapek (1914) has suggested that the phisnia membrane is com-posed of soaps. Nathanson (1914) regards it as mosaic of lipoid andnon-lipoid particles. This would not provide an entrance for lipoid-soluble and lipoid-insoluble substances into the cell-sap unless each ele-ment of tlie mosaic extended continuously, without a break, from theouter surface to tlio vacuolo. For a general summary see Bayliss (I9ir>),ilober (1914), and AlcClendon (1917). CONDUCTIVITY AN J) PKKMEABJLITY 231 tlie pigment. This can easily be shown by killing the cell,wherenpon the semii)ermeable membranes are destroyedand the pigment at once begins to diffuse out. In thiscase, we have to do with variety of semipermeable mem-In-anes, such as the plasma membrane, the surfaces of theplastids, the vacuolar surface,^ and the nuclear surface.It is to be expected that these surfaces may differ some-what in permeability. Each of them is in contact with b c
