Thus a serum which will agglutinate its homologous strains in dilutions of one 1:1,000 will often fail to agglutinate other races of Bacillus coli in dilutions of 1:500 or 1 : 600. The normal serum of adult animals and man will often agglutinate this bacillus in dilutions as high as 1 : 10 or 1 : 20—a phenomenon pos- sibly referable to its habitual presence within the body.

HATHAWAY Species specificity of respiratory activators Although the agglutination of spermatozoa by egg water is highly specific (Lillie, 1919; Metz, 1945; Tyler, 1948), there has been no clear demonstration of specificity among activators of sperm motility and respiration. A specific activator was thought to occur in starfish egg water (Loeb, 1915), but it was later demon- strated that starfish spermatozoa are virtually immotile in both sea water and egg water (Metz, 1945).

On the other hand, the combining sites of the soluble antigens in frozen-thawed extracts evidently are blocked by fertilizin. This is again seen in Figure 3, curve c.

The first report of inhibition of this type was that of Watkins and Morgan (1952) who, in this case using anti-H agglutinin of eel serum, discovered that agglutination was inhibited by L-fucose. In addition to certain simple sugars, the sugar derivation N-acetyl- galactosamme inhibits anti-A, and anti-B agglutinins from a number of sources (Makela, 1957). This observation a
