"Ehrlich's diagrams illustrating the mechanism of immunity and cytolysis. The figures in black indicate substances with toxic action. a and b illustrate the excessive production of receptors in response to the action of toxins, and their escape from the cells." -Whitney, 1911

"Ehrlich's diagrams illustrating the mechanism of immunity and cytolysis. The figures in black indicate substances with toxic action. a and b illustrate the excessive production of receptors in response to the action of toxins, and their escape from the cells; in b they are seen to combine with toxin outside the cell, preventing its union with the cell." -Whitney, 1911

Cytolysis, Stage 2

"Ehrlich's diagrams illustrating the mechanism of immunity and cytolysis. The figures in black indicate substances with toxic action. c shows the structure of the complement and intermediary body of bacteriolytic and cytolytic sera." -Whitney, 1911
