At the end of this article there is appended a series of our ward record charts of patients who developed pneumonia following the influenza. These charts are shown to indicate the results of giving immune convalescent citrated blood in pneumonia. The ones presented are from some of the group which recovered. We have, of course, the charts from the fatal cases, but as they do not bring out any special point, save that there was little or no change after treatment, we are omitting them. It is not our idea, however, to give the impression that we have had nothing but success with this method of treatment. It might be well to emphasize some of the salient points which are brought out. (1) The regularity of the drop in temperature after the injection is almost generally demonstrated. (2) The occasional chill following the injection seemed to have no untoward results. (3) The leucocytes show, as a rule, little or no variation after transfusion. Our work agrees with McGuire and Redden’s statement that the cases with a leucocyte count under 10,000 give the best results with immune serum. (4) The time of injection in many of the cases was by no means ideal, in that the disease was advanced; and again in many the injection should have been repeated sooner. This, however, is no fault of ours. (5) One injection of 50 cc. of citrated blood from a good donor, if given early enough, may be all that is necessary. Several charts bear out this statement. (6) The day of disease is dated from the onset of the influenza. The demonstrable signs of pneumonia correspond roughly to the initial rise in temperature following the influenza. The day of disease of the pneumonia is not indicated on the chart, as this information we have obtained from the daily notes. _Complications_ The epidemic was well spent before we observed many complications, save those referable to the lung. Later various forms of sequelæ have been appearing. One must guard, however, against the danger of attributing all of our ills to the past epidemic. We are not going to give in detail the treatment of these various conditions, nor even mention all of the many complications. The main points, however, we desire to emphasize.
