On examining the sputa it was found glairy and tenacious, and not such as we find in inflammatory conditions of mucous membrane of the air passages. I had given him a mixture which included compound tinct. benzoin and codeine without effect, but now being convinced the affection was of neurotic origin, it occurred to me to make a trial of tincture nux vomica in my one-drop-five-minutes-dosage. I timed my call the next evening so as to be present when the paroxysm of cough commenced. My patient had just finished his evening meal, and we had been conversing hardly ten minutes when the cough set in and rapidly increased in violence, and then came my opportunity for the crucial trial of nux vomica in this case. When I had given the seventh one drop dose the paroxysm began to yield, and by the time we had given the tenth dose it was almost over, the patient having an occasional cough. My patient was very happy over the sudden and unexpected relief afforded by the medicine I had just given him in such small doses, and of course was curious to know what it was. He then told me, these hard paroxysms sometimes lasted up to midnight, and on one occasion it had lasted almost until morning. I left him drops to take in the night in case he should have another paroxysm. When I reached home that evening I do not think my patient was any happier than I was over my success with the nux vomica in a purely experimental case. The next morning Mr. M. informed me that he had slept through nearly the entire night, which, owing to the cough, he had not been able to do in a week. The patient from that night had no return of severe paroxysm of coughing. I furnished him with fresh drops every day, and he became so well posted in their dosage and use that in a few days the cure of the cough was complete. And I may here add that I have had several similar cases of cough since that, and the nux vomica has succeeded in all. If physicians would more closely diagnose their cases of cough, I will venture to say, there might be discovered more than one case of neurotic origin and laryngeal.
