bad cases of bronchitis, but generally attend upon all cases 

 of pneumonia and pleurisy the chief distinguishing marks 

 are the following: 



1. BRONCHITIS. Cough incessant, not so painful, expectora- 

 tion frothy, and white or yellowish, wheezing, and bubbling 

 sounds heard by auscultation ; percussion gives considerable

3. PLEURISY. Cough slight, dry, short, and very painful ; no 

 expectoration, no wheezing or crackling sound, but a dry grating 

 sound heard in the early stage, and pain felt on tapping the side

 and bronchitis, but do harm in pleurisy. In pneumonia and
