3. The filtration and diffusion of mixtures show that free lysin is present in 
neutral mixtures and in mixtures containing excess of antilysin. 
4. Free antilysin exists in neutral mixtures, and in mixtures containing 
excess of lysin. | 
5. The reaction is at least partially reversible when excess of antilysin is 
present. 3 
6. False equilibria are produced with greater facility when the lysin is in 
€XCess. 
1. The neutralisation equation of Arrhenius and Madsen does not hold for 
multiple mixtures. 
8. The removal of lysin from a solution by antilysin is not capable of inter- 
pretation as a purely chemical change, but is more analogous to certain 
adsorption phenomena.
