Abstract

What can be learned from the viscosity data that have been presented? Certainly if students of protoplasmic viscosity were content merely to discover whether this or that condition or this or that agent caused an increase or a decrease in the viscosity, not very much would be gained from the enterprise. Surely the main point in making viscosity measurements is to find out as much as possible about the protoplasmic colloid, what it is like in the resting cell, how it changes during activity, what factors are involved in its deterioration with age, and how it is affected by various chemical and physical agents. At the present time there is no better way of studying the protoplasmic colloid than to measure its viscosity. And indeed there is no more sensitive indicator of the physical changes that are occurring in the living cell. Fortunately, proper viscosity measurements can be made on living protoplasm; and generally speaking, the protoplasm does not suffer at all as a result of the measurement.
