154 Wisconsin Academy of Sciences, Arts, and Letters water under examination. The presence of the other factor or factors reduces its actual effect by reducing the quantity of radiation on which it can operate. The set of factor curves for any water may be computed as additive absorption curves, as is done for Nagawicka Lake, Fig. 38, pp. 128-129. 8. Factor curves for color and for suspensoids may be computed in certain cases where the regular methods cannot be applied. Three such cases are shown in Figs. 50, 51, 52 and accompanying text. 9. Mean factor curves for absorption by color are given in Fig. 53 for the spectral region 4000-7000 A and for colors 0-180. Corresponding transmission curves are given in Fig. 54.
