1. The Relations Between Antigen and Antibody in the Living Organism Richard Weil: (President's address, see this volume, page 399.)
2. The Treatment of Dermatitis Venenata by Vaccines Albert Strickler: This study was undertaken with the object of throwing some light on a number of factors relative to dermatitis venenata: (1) the elaboration of an endermic skin test; (2) to determine whether the intramuscular injection of the homologous vegetable toxins would influence the course of dermatitis venenata; (3) whether it is possible to desensitize individuals by the injection of the homologous vegetable toxins and (4) whether complement-fixing bodies could be found in the sera of patients that have had an attack of dermatitis venenata and have been treated by the injection of the homologous vegetable toxins.
The vegetable toxins of ivy, sumac and nettle were isolated and these were employed in our experiments.
