The preeipitability by antisera of carbohydrate fractions prepared from several of the yeast-like fungi as described in a previous report from this laboratory (1), and the ability of these fractions to induce anaphylacfie death in sensitized animals as reported in the preceding paper (2), are to be looked upon as examples of immune reactions with non-antigenic haptens. As already briefly reported (3), another reaction of the same type consists in eliciting an inflammatory response in a previously locally sensitized eye by subsequent intravenous administration of the carbohydrate fraction derived from the sensitizing organism.In various studies of sympathetic ophthalmia, attempts have been made to produce an inflammatory reaction in a previously locally sensitized eye, as well as the opposite eye, bysystemic administration of the homologous antigen. Kfimreel (4) injected serum or uveal emulsion into the vitreous humor of one eye and subsequently reactivated the eye by subcutaneous or intravenous injection of the same antigen. Fuchs and Meller (5) reported the production of an iritis by intravenous injection of human serum into an animal sensitized intraocularly 35 days previously. The reaction took place, however, in only one animal of the series used. Schoenberg (6) injected human serum into the anterior chamber of rabbits, followed in 2 weeks by intravenous injection of the same antigen. This, as well as a similar experiment using tuberculin, was negative. Von Szily (7), working with Arisawa, injected foreign serum between the layers of the rabbit's cornea. Later, with all inflammation absent, intravenous injection of the same antigen caused an "anaphylactic keratitis" in the sensitized eye. Subsequently however, yon Szily (8) injected relatively pure pigment from the uveal tract of cattle into the vitreous humor of rabbits. Intravenous injection of large amounts of the same pigment 3 weeks later was without effect. A similar experiment by 815
