[An example of gaining a growth function by its increase values (author's transl)]

In continuation of recent investigations of the author into mathematical presentations of organic growth an analytical expression for an increase function is postulated. Based on observations of growth processes by many authors as accumulated by HOEPPE (1959) a 2 term product of higher degree parabolas has a chance as being representative of a more frequent increase behaviour allowing direct integration to the growth function proper. An example is added for means of comparison with formerly developed growth functions.
