_Chronic Bronchitis_, when arising as a primary disease, presents some or all of the previous symptoms, but in a considerably modified form; the fulness in the windpipe, oppressed and laborious breathing, hoarseness and cough, are, however, the most general symptoms of chronic bronchitis; the expectoration, though after a time becoming more free, is far from being copious, and consists of a discoloured mucus; sometimes of a purulent appearance, at others stained with blood, or streaked with a brick-coloured fibrinous matter. The symptoms are generally exaggerated towards night, when they are attended with increased fever and night sweats. _Treatment of Acute Bronchitis._—In full-bodied constitutions, if the disease be taken in its first stage, bleeding to the extent of eight or ten ounces may be very safely and beneficially employed; but as the debility that attends bronchitis is both great and sudden, unless adopted in the _earliest_ stage, the practice would be highly culpable, as all the physical stamina is required to throw off the collected mucus from the bronchial passages so bleeding; therefore, unless employed early, it can never properly be practised. When necessary, an emetic must be immediately given, consisting of antimonial and ipecacuanha wines, of each half an ounce, or the following powder:—Ipecacuanha 15 grains, tartar emetic 1 grain, mix; to be dissolved in a little warm water and drunk directly, following it up by frequent draughts of warm water. If the first emetic does not operate freely, repeat the same dose within the hour, assisting the action, if necessary, by tickling the throat with a feather. As soon as the vomiting has subsided, apply a blister three inches wide by six inches long, down the centre of the chest, and give a table-spoonful of the mixture below every two hours. Take of Distilled Water 6 ounces. Tartar Emetic 6 grains. Powdered Nitre 1 scruple. Dissolve, and add tincture of colomba, 2 drachms—mix. At the same time, between the doses, let the patient inhale the steam of hot vinegar and water, and wear a veil over the face, so as always to breathe through a medium. When the blister has risen and the plaster has been removed, apply a hot bread poultice, which repeat every hour, for two or three times; and finally, dress with violet powder. When the expectoration changes its character and becomes thick, greenish and ropy, it will be necessary to give stimulating expectorants, to facilitate the discharge; for that purpose, the annexed mixture, in doses of a table-spoonful every three or four hours, is to be employed. _Expectorant Mixture._ Gum Ammoniacum 2 drachms. Carbonate of Ammonia 1 drachm. Rub into a powder, then add a tea-spoonful of water; triturate till the whole is rubbed into a smooth creamy paste, when add, by degrees, six ounces of water.
