Microscopic examination of the viscera showed acute congestion and some degree of cloudy swelling in the liver and kidneys. The sections of the lung through the consolidated area showed the pleura replaced by a thick layer composed of large and small mononuclear cells, some red blood cells, a rare polymorphonuclear cell, and great numbers of fibroblasts and budding capillaries. Some of the alveoli contained many red blood cells, a few polymorphonuclear and mononuclear cells, some fibrin, and in many areas fibroblasts were organizing this exudate (Fig. XLV). Organization was also present around the bronchi and these contained mucus, pus, and desquamated epithelium. Frequently strands of fibroblasts were seen sweeping through the bronchiolar exudates, and in a few instances they had completely filled the lumina. II. INFLUENCE OF THE RESPIRATORY COMPLICATION OF INFLUENZA UPON TUBERCULOSIS OF THE LUNG Thirteen of the ninety-five cases included in this report occurred at the United States General Hospital No. 16, one of the large tuberculosis camps. In five instances the patients had active pulmonary tuberculosis. The remaining eight were members of the detachment and may be added to the eighty-two from the New Haven Hospital, making a total of ninety cases in which there was no clinical evidence of active pulmonary tuberculosis at the onset of the acute respiratory disease. When these ninety cases are analyzed, it is found that only two of them show definite activation of an old tuberculous focus (82). One has already been referred to (Autopsy No. 209); the other, presenting a much more acute exudative and ulcerative tuberculosis, deserves special consideration. _Autopsy No. 194._ A white female, aged 27 years, was admitted to the New Haven Hospital on November 8, 1918, complaining of “cold on the chest, fever, cough, and prostration.”
