Mathematical representation of the general pattern of biological growth in unicellular or multicellular organisms is feasible. The weight of the organism is a practical variable for the description of this growth. The resultant differential equation contains a term representing the inhibitory effect of increase in size of the organism due to encroachment upon space and a term representing the, accumulation of toxic products. The solution for the weight rises from a low initial value to a maximum and then decays gradually, the ascending and descending curves being independent of each other. The solution appears to have value in integration and simplification of complex and variegated biological phenomena.
