Fig. 5&.— Curves showing the average relative sizes in volumes of yeast cells 

 in various concentrations of KC1 and MgCL. The ordinates represent the 

 volume of the yeast cells and the abscissae, the concentrations of the salts used. 

 The ordinate at represents the volume in blank cultures. 



Pig. 5c. — Appearance of yeast cells in extreme concentrations of salts. 



Normal yeasl cells in 1, 2 and 3, diseased yeast cells from extreme concen- 

 trations of KC1 ami MgCL in 4 and 5; (white) and diseased yeast cells from 

 extreme concentrations of CaCL and NaCl in 6, 7 and S (black or shadowy) 

 (X5000).
