This power of _Bacillinum_ to relieve oppression in pulmonary catarrh is in no way surprising from the point of view of the law of similars; for in the acute and infectious stage of tuberculosis the dyspnoea is a characteristic symptom, and is far more distressing than the cough. I have read with pleasure in the work of Dr. Mersch, of Brussels, on _Tuberculin_, of a fact which corroborates my statement as to the influence of _Bacillinum_ over catarrhal dyspnoea. After the sixth dose the patient, who was suffering from bronchial asthma, was seized with violent intercostal pains, with augmented cough; but the oppression entirely disappeared after the first day, and did not return even three months after the treatment had ceased. In _L' Art Médical_ of January, 1894, and in the _Hahnemannian Monthly_ of July, 1894, I published the case of an old man of eighty years of age, suffering from broncho-pneumonia, who, in the last stage of asphyxia, had been saved by _Bacillinum_. Two years ago I was called upon to treat another octogenarian who, as the result of a cold, developed an obstruction in the bronchial tubes, and at the basis of the lungs. He passed sleepless nights in a sitting posture, striving to draw deep inspirations. _Phosphorus_, _Arsenic_, and _Stibium_ produced no relief. I gave him _Bacillinum_ 30th, and he slept the whole night through. Doses of this remedy, administered _at longish intervals_, always produced a remarkable amelioration. Last year I was called to the house of an upholsterer. He preferred not going to bed at all to passing the night in bed without closing his eyes. He had humid asthma with incessant cough, which ended by causing him to eject thick yellow and puriform mucus. For eight days he took _Arsenic_ and _Blatta_, and for a whole week he passed the nights without sleeping. From the day he took _Bacillinum_ he was able to sleep. I saw him again this year in good health. Once or twice he was attacked with the same bronchorrhea, and had my prescription made up at the chemists, with the same success. This year, too, I have given _Bacillinum_ to several patients at the Hôpital St. Jacques for the same symptoms, and it has never yet failed me.
