creased additions of albumen have no effect. Albumen 

 and serum have in this repect the same effect upon sodium 

 hydrate and ammonia, i.e. the action upon the higher 

 concentrations of the ruemolysing body is propor- 

 tionately much greater than upon the lower concentra- 

 tions. It would therefore seem as if the albumens added 

 diminish the strength of the chemical combination, 

 which the haemolysing bodies, to begin with, form 

 with the red blood corpuscles. We will return to this 

 phenomenon later on. 



The normal serum has, as above mentioned, a very 

 great effect upon the tetanolysin. In the table below, 

 the figures indicate the amount of serum added to the 

 toxic fluid, multiplied by 100000.
