The Respiratory Passages 

 are all lined by the mucous membrane. 

 Catarrh, 



or cold, inflammation of the upper air passages, should never 

 be long neglected. A few mashes or a little medicine will 

 usually remove it. If it is neglecetd, and, occasionally, in 

 defiance of all treatment, it will degenerate into other dis- 

 eases. The larynx may become the principal seat of inflam- 

 mation. 



Laryngitis 



will be shown by extreme difficulty of breathing, accom- 

 panied by a strange roaring noise, and an evident enlargement 

 and great tenderness of the larynx when felt externally. The 

 windpipe must be opened in such case, and the best advice 

 will be necessary. Sometimes the subdivisions of the trachea, 

 before or when it first enters the lungs, will be the part 

 affected, and we have bronchitis. This is characterized by a 

 quick and hard breathing, and a peculiar wheezing sound, 

 with the coughing up of mucus. Here, too, decisive meas- 

 ures must be adopted, and a skillful practitioner employed. 

 His assistance is equally necessary in 



Distemper, Influenza and Epidemic Catarrh, 



names indicating varieties of the same disease, and the pro- 

 duct of atmospheric influence; differing to a certain degree 

 in every season, but in all characterized by intense inflam- 

 mation of the mucous surfaces, and rapid and utter prostra- 

 tion of strength, and in all demanding the abatement of that 

 inflammation, and yet little expenditure of vital power. 

 Cough may degenerate into 



Inflammation of the Lungs ; 



or this fearful malady may be developed without a single 

 premonitory symptom, and prove fatal in twenty-four or even 

 in twelve hours. It is mostly characterized by deathly cold- 

 ness of the extremities, expansion of the nostril, redness of 

 its lining membrane, singularly anxious countenance, con- 

 stant gazing at the flank, and an unwillingness to move. A 

 successful treatment of such a case can be founded only on
