Confirmation is presented Lillie's finding sperm cannot be re-agglutinated after reversal initial agglutination. also reversed are incapable fertilization.3. Appropriate heat treatment converts fertilizin into substance does not cause agglutination but still combines with by inability subsequently agglutinated ordinary and loss fertilizing power. accordance assumption multivalency lattice theory agglutination, modified assumed univalent. found non-dialyzable.4. starfish Urechis egg water contain specific sperm-combining (univalent fertilizin) causing iso-agg...
