II, the mortality of the digitalis treated cases is higher than that of their controls. The only exception to this is that the higher mortality in the digitalis treated cases is found in the younger age group with type II pneumococcus infection. No explanation has been found for this exception. Possibly the factor of virulence in producing septic complications may determine it. The last table shows that the incidence of auricular fibrillation and auricular flutter is the same in the control The mortality is, however, distinctly higher in the and the digitalis treated group. digitalis treated group. In conclusion, the Committee prefers to continue this investigation on the results of digitalis therapy in pneumonia and to observe a larger number of cases over a series of years. It was the unanimous opinion of the Committee and its advisers that the results obtained thus far do not justify continuing the routine administration of digitalis to patients suffering with lobar pneumonia.

The hearts of one hundred cases without hypertensiou or heart disease coming to autopsy showed that the weight of the heart in this series is on the whole lower than that in the nontuberculous. Nearly one-third of this group had a cardiothoracic index below 40 per cent as compared with one-fifth in the normal. The electrocardiograms of this group of patients following collapse therapy revealed that a high percentage (60 per cent) showed low voltage in one or more leads, the amplitude of the ventricular complex measuring not more than 5 mm. Roentgen ray studies indicated that the heart shadow was displaced by tuberculous processes in a considerable number of cases. Study of electrocardiograms in these cases with displacement of the heart shadow yields insignificant results. The incidence of low voltage is practically the same iu the right-sided heart and in the normally placed heart. The infrequent occurrence of low voltage in Lead I in the presence of left heart displacement is the only point worthy of note in these figures.

Collapse on
Electrocardiograms have been studied in sixty-six patients who have undergone seventy-three pulmonary collapse procedures, analyzing findings before and after collapse. These procedures are almost invariably followed by changes in amplitude of the electrocardiographic waves, R-wave modification occurring in 96 per cent of the cases, but the type and the degree of variation are not constant or predictable, according to either the side involved or the procedure carried on. Evidence suggests that the changes are due to changes in heart position, influenced largely by pleural and mediastinal ndhesions, more than by myocardial factors.
