INFLAMMATION OF THE LUNGS.

and each of these is the seat of a peculiar inflammation {pleurisy, 

 pneumonia, and bronchitis), attended by different symptoms and 

 requiring a variation in the treatment. There is also, as in all 

 other inflammations, an acute and a chronic kind, so that here we 

 have six different inflammatory disorders of the contents of the 

 chest, besides heart disease and phthisis or consumption, which 

 last requires a separate notice. All the acute forms are attended 

 with severe sympathetic fever, and with a quick pulse ; but the 

 character of the latter varies a good deal. The chronic forms 

 have also some slight febrile symptoms ; but generally in propor- 

 tion to the acuteness is the amount of this attendant or sym- 

 pathetic fever. As these three forms are liable to be easily 

 mistaken for each other, I shall place the symptoms of each in 

 juxtaposition in the following Table : —
