They also show that salts or elec-trolytes were probably no longer present in the cells and thatoxidative processes had ceased, because the simple addition ofsalts to the medium resulted in the restoration of vital they indicate that the nucleus of the cell is probably theseat of manufacture of the oxidative ferments or
