Further, the serum of a patient affected with one of the types has a marked agglutinative power on the variety with which he is infected and not on the other.
Of these the most important are (a) bacteriolytic or lysogenic action, (b) agglutinative action, and (c) opsonic action.
Briefly considered there are six most striking proofs that the Sumerian was based on a primitive agglutinative language.
Sumerian has a system of vowel harmony strikingly like that seen in all modern agglutinative languages, and it has also vocalic dissimilation similar to that found in modern Finnish and Esthonian.
Sumerian has only postpositions instead of prepositions, which occur exclusively in Semitic. In this point also Sumerian is in accord with all other agglutinative idioms. Note Sumerian e-da, " in the house " (e, " house," +da, " in," by dissimilation), and compare Turkish ev, " house," de, " in," and evde, " in the house."
