The Velocity of Reaction, etc. 



Conclusions. 



1. The establishment of equilibrium in the absorption of agglutinins by 

 their specific bacteria is not attained, as stated by Eisenberg and Volk, in 

 less than five minutes at 0° C, but takes a considerable time, since 

 equilibrium is not reached at room temperature even in four hours. 



2. The adsorption of agglutinin or trypsin by charcoal has not reached an 

 equilibrium within four hours at room temperature, and the adsorption 

 of sulphuric acid by charcoal not in 24 hours, or possibly even in 48 hours. 



3. There is no justification for judging as to the nature of the interaction 

 between an absorbing material and a substance absorbed, from the rapidity or 

 slowness with which equilibrium is attained, as has been done by Arrhenius.
