In our series Pneumococcus type VII (Cooper) was responsible for 6.5 per cent of the cases of pneumococcic pneumonia in adults and for 2.4 per cent of the cases of pneumococcic pneumonia in children.

During the seven years from 1928 to 1935 there were observed in the wards of the Harlem Hospital 218 patients with pneumonia due to Pneumococcus type VII. Of these, 200 were adults and 18 were children. The number of cases and the relative incidence of this type of pneumonia varied from year to year. In the series for adults in the years 1929-1930 and 1930-1931 the cases of pneumonia due to Pneumococcus type VII were relatively most numerous, 37 cases (9 per cent). In the year 1934-1935 this type occurred in 24 cases, only 4.6 per cent of the total number of cases of pneumonia for that year.1
