Of these the most important are (a) bacteriolytic or lysogenic action, (b) agglutinative action, and (c) opsonic action.

Agglutinative action is evidence of the presence in a serum of a somewhat similar set of substances, known as “agglutinins.”

In the agglutinative languages, or at any rate in some of them, some of the post-fixed elements have still an independent value.

The main differences shown by these varieties are agglutinative differences.
