Heighten electromotor 

 power. 



Cause swelling and cessa- 

 tion. 



Excites motion in sperma- 

 tozoids. 

 Stimulates. 



By coagulating albumen 

 they mechanically cause tur- 

 bidity, swelling and death. 



Stimulates. 



No special toxic effect. 

 Instantly destroys. 



Stimulates at first, then 



10 I gradually destroys. 



If very dilute, stimulates. 

 If concentrated, destroys the 

 movement mechanically by 

 coagulating albumen of cell, 

 and dissolves cilia. 



Weaken electromoter 

 power. 



If very dilute, stimulates. 

 If concentrated, destroys 

 movement and produces tur- 

 bidity. Chloroform leaves 

 the least injurious effects. 



Destroys gradually, but 

 may be revived after pres- 

 sure of eight atmospheres. 



Pure. 



ANIIDOTE. 



Uninjurious 

 gases, air or neu- 

 tralization if not 

 too advanced. 



Neutrahzation in 

 early stages. 



None.
