Fig. 3. Effect of electrolytes in restoring the activity of enfeebled trout 

 sperm. Graphical interpretation is the mean of several observations. The 

 activity number is an arbitrary scale varying from full motility (10) through 

 oscillation of all cells (6) to one cell seen oscillating in every field at high 

 power (1) to no movement whatsoever (0).
