The use of tartrates and citrates, as in “imperial drink” in a condition where we know some kidney impairment is present, is possibly flying in the face of danger—especially in view of the fact that these salts are so available in the production of experimental nephritis. But we have only to see their application in the human in mercury bichloride poisoning, where an intense nephrosis usually develops, to fully realize that these salts may be given without danger to the kidney. We do not suggest that the kidney lesions of influenza and mercury bichloride poisoning are the same. We are merely bringing out this point of analogy in support of their use in certain desirable cases. The respiratory symptoms gave us more concern than any other phase of the uncomplicated case. The irritating, distressing, non-productive cough suggested both a sedative and expectorant. Ammonium chloride (gr. iii-v, t. i. d.) was the usual expectorant. It seemed to increase in value with the more chronic type of case. It is our impression with those acute hacking coughs that the sedatives produced more gratifying results. Elixir terpin hydrate with heroin, codeine and occasionally morphine were preferred. When good results were noted sedatives were given liberally. Steam inhalations combined with tr. benzoin co., followed by spraying the throat with medicated liquid petroleum, gave some relief. The tendency to œdema, however, as we saw it in the cases complicated by pneumonia made us hesitate to use inhalations. Possibly the fear was groundless. Morphine (grs. ⅙) was given for sleeplessness, and it was repeated if necessary. Cardiac stimulants were rarely needed. The tincture of digitalis was the choice, but in the uncomplicated cases was very seldom used. At the beginning of the epidemic we prescribed whisky in almost every case. Our idea was that it would have a sedative action. At the present time we are very doubtful of its value. Toward the end of the epidemic we used it very moderately. The results obtained possibly depended for the most part upon the type of patient. Some of the soldiers asked to have it discontinued, not from any moral point of view, while others wished more frequent doses. The elderly patients seemed to appreciate this remedial agent to a fuller extent. _Pneumonia_ The pneumonia following the original infection was, from the standpoint of physical diagnosis, often difficult of diagnosis in its early stages. The infection commencing as an influenza would at times pass imperceptibly into pneumonia, and obviously the points brought out in the previous paragraphs on treatment were applied until the diagnosis of pneumonia had been established. Some new factors were peculiar to the pneumonia and demanded further changes in the handling of the cases.
