This conclusion was expressed in the preliminary paper (Loosanoff, Miller and Smith, 1951). Plotting of the dates of beginning of setting in the different cultures against the temperatures showed that the mean number of days for setting to begin for the various temperatures lies on an almost straight line (Fig. 1).
