As in Fig. 10, LiCl-treated proteins precipitate at lower ammonium sulfate concentrations, KSCN-treated proteins precipitate at higher ammonium sulfate concentrations. (From Ranzi, 1955.) /' actom.

On the abscissa is plotted the final molar concentration of the added salts (LiCl or KSCN). Ionic strength is I = in all samples. LiCl induces an increase in viscosity, KSCN induces a decrease in viscosity. The sketches of the embryos (normal, vegetalized, and animalized) are located according to the active concentration in modifying the development. (From Ranzi, 1955.).
