If the reaction to tuberculin is regarded as an allergic response due to the interaction of antigen and antibody3 and if the thesis is accepted that absorption into the system of an adequate amount of specific protein produces an active sensitization to that protein,4 it would be reasonable to expect the development of a specific sensitivity of the tissues after repeated intradermal or subcutaneous injections of sufficiently large amounts of tuberculin.
