Stimulant expectorants encrease secretion and give tone to the 

 mucosa, and are especially valuable in cases in which the bron- 

 chitis is already well established, during convalescence, with 

 weak heart, and in the chronic cases. These include inhalations 

 of ammonia or alcohol, strychnine, squills, senega, all aromatic 

 volatile oils, oleoresins and balsams. 



Antiseptic expectorants are especially needed when the sputa is 

 delayed and decomposed in the tubes, causing a foul smelling 

 breath and discharge. They include carbolic acid, creosote, creo- 

 line. cresyl, terpene, terpinol, terebene, oil of turpentine, oil of tar, 

 menthol, eucalyptol, etc. They may be administered, diluted, as 

 intratracheal injections, by inhalation with steam, or in an atom- 

 ized condition. Like stimulating expectorants, these are of great 

 value in many chronic cases. 



For stimulating the respiratory centres directly strychnia and 

 ammonia are especially indicated, while to quiet their irritability, 

 opium, bromides, chloral, and chloroform may be used. Opium 

 is usually objectionable in the early stages as calculated to arrest 

 and prevent secretion, but in combination with an expectorant 

 like ipecacuanha it forms an ideal soothing expectorant. 



The mildest cases will recover of themselves, especially if care 

 is taken to protect the patients against cold, wet, draughts of 

 cold air, over-exertion, and other injurious causes, and to give a 

 part of the food warm and sloppy. In severe cases treatment 

 must be more active, but it will be borne in mind that severe 

 depletive measures are_ badly endured. Bleeding dangerously 

 increases the already existing weakness and prostration, without 

 affording any corresponding advantage. It is only admissible 

 when from the -severity of the symptoms in the early stages, suf- 

 focation is threatened, or, when the brain becomes involved in 

 disease. 



Causing the patient to inhale water vapor from scalded bran or 

 hay is to be assiduously carried on for half an hour to an hour 

 twice or thrice daily until expectoration has been freely established 

 and the cough and fever alike moderated. The density of the 

 vapor must of course be apportioned to the particular case so as 

 to avoid any approach to suffocation. The addition of the fumes 

 of burning sulphur will often by their astringent and antiphlogistic 

 action on the mucous membrane, render the vaporous application
