Fig. 29.—Diagram illustrating the Neisser-Wechsberg phenomenon of "de- viation of ; In A^ the three black units (c) represent the quantity of complement necessary for the dissolution of a bacterium, and the three white units (i) the intermediate bodies or amboceptors through which they may act. A' shows these properly proportioned units properly combined and anchored to the bacterial cell which will be destroyed. If an excess of amboceptor units be present, as is suggested in B^, the resulting combinations and the consequent results may vary according to the difEering combining afiSnities. Thus, B^ shows an unchanged affinity, , only those amboceptors unite with bacterial cells that are charged with complement. C shows equal affinity of the amboceptors for complement and for the bacterial cell, so that charged or uncharged units attach themselves to the cell, diminishing the complementary action. D' shows the possible result when the affinity of the amboceptor for the bacterial cell is diminished after charging with complement, so that though the complement and amboceptor combine, there can be no destruction of the bacterium. Thus, excess of the amboceptor units may "deviate the complement" and prevent its action. the amboceptors is diluted until their number becomes approximately equal to the number of complements introduced, any deviation resulting from inequality of the combining affinities becomes im- probable. Bordet and Gay,* however, have performed experiments tending to show that these elements do not really unite, thus seem- * "Ann. de I'lnst.
