Abstract
In the rabbits sensitized in whole bodies with the normal duckserum by the intra-(sub-) cutaneous or intraveneous injection, the dermatoreaction appears monomophically when the anti-rabbit-kidney-duck-serum is injected intra- (sub-), cutaneously to the other place from the sensitized place. I conclude that the normal anaphylactic reaction caused by the duck-serum in the anti-rabbit-kidney-duck-seum appears promptly in the injected place after the injection of the anti-rabbit-kidney-duck-serum, duplicated with the contradictory anaphylactic reaction caused by the nephrotoxin in the anti-rabbit-kidney-duck-serum.
