268 SEROUS SYSTEM. 



Q. How does chronic pleurisy differ from phthisis? 



#. The cough is drier, there are no night sweats; the 

 pain is fixed, and in pleurisy there is local dropsy with its 

 indications ; whereas, in phthisis there is cellular dropsy. 



Q. What effects have diseased lungs on the pleura? 



Ji. They induce chronic pleurisy. 



Q. Are there any certain indications of effusion in the 

 pericardium? 



.#. If any one will distinguish it from surrounding dis- 

 ease, it is pressure on the epigastric region, which throw- 

 ing up the fluid, occasions suffocation. 



Q. What are the terminations of pericarditis? 



t#. In adhesion, suppuration, in effusion of serum, and 

 in a greatly increased thickness. 



Q. Is the peritonitis as local as the pain in that dis- 

 ease? 



ft. Although the pain may be locally very acute, yet 

 the inflammation is diffused. It is the same case with 

 pleurisy, in which the pain is pointed, although the in- 

 flammation is extensive. 



Q. Whence does the vomiting in peritonitis arise ? 



#. It is sympathetic, not from irritating gastric con- 

 tents. 



Q. Mention a very remarkable distinction between pe- 

 ritonitis and dysentery. 



#. In peritonitis the bowels are costive or natural, in 

 dysentery the stools are characteristic of mucous irrita- 

 tion. 



Q. How does peritonitis terminate? 



#. In adhesions of the intestines to each other, in 

 serous effusion, in the formation of pus, and in gangrene 



Q. Where are these adhesions most conspicuous?
