This communication is based on observations of 401 proved cases of bronchogenous staphylococcic pneumonia seen during a period of more than fifteen years. We have excluded from this study all cases of staphylococcic sepsis with metastatic pulmonary abscesses. We shall propose a concept of the pathogenesis, outline the pathology,
