of this organism.
Through these discoveries he laid the foundation for his brilliant analysis in chemical terms of the antigenic constitution of the whole pneumococcus.  He thus established a perfect pattern for the antigenic analysis of other micro-organisms both by himself and by others who have followed in his footsteps.
Among Dr. Avery's many brilliant contributions to scientific knowledge none has been more outstanding than his studies on the antigenic constitution of bacteria.  Through them he is one of the founders of the science of immunochemistry.  Because of them our comprehension of the complex problems of infectious disease has been immeasurably enriched.
