erally increased temperature of the body (102" to 104° F.), accel- 

 erated and labored breathing with double lifting of the flank in ex- 

 piration, and other manifestations of fever, there are more specific 

 symptoms. The cough is dry, hard, painful, often paroxysmal, 

 and appears as if it came from the very depth of the chest. A 

 strong, harsh, blowing bronchial sound is heard over the lower end 

 of the trachea and the upper border of the middle third of the chest, 

 just behind the shoulder. Percussion detects no change from the 

 natural resonance of the chest, nor auscultation any crepitating 

 sound. Pressure in the intercostal spaces causes no suffering. 

 The expired air feels hot. The pulse though accelerated is moder- 

 ately soft and sometimes even weak, a condition which marks in- 

 flammations of mucous membranes as contrasted with those of the 

 serous. The mucous membrane of the nose has a dark red hue, 

 especially when the inflammation extends to the smaller ramifica- 

 tions of the bronchial tubes so as to impair the seration of the 

 blood. In the same state there is excessive dullness and prostra- 

 tion because of the supply of partially venous blood to the brain. 

 The head is held low, the nose often supported upon the manger, 

 and the eye-lids are semi-closed and injected. 



From the second to the fourth day a free exudation takes place 

 from the surface of the mucous membrane, and the symptoms are 

 materially changed. The cough becomes more frequent but 

 softer, looser, and attended with a rattle, heard in both inspira- 

 tion and expiration, from the air passing through the abundant 

 mucous secretion. The cooing or tubal sound heard at the lower 

 end of the windpipe and behind the shoulder has now given place 

 to a mucous r&le. A nasal discharge appears at first watery, thin, 

 of a whitish, glairy froth, but soon becoming more opaque, white, 

 milky and flocculent and having little tendency to stick to the nos- 

 trils. This is often expelled with sneezing and accompanied by 

 movement of the jaws. With the access of free secretion there is 

 a great mitigation of the fever and the other distressing symptoms, 

 and, if no relapse nor complication supervenes, recovery may be 

 complete in a fortnight or three weeks from the onset. 



From this time all the febrile symptoms decline and disappear, 

 appetite and liveliness return, the discharge rapidly diminishes 

 and finally disappears, when the patient may be said to have com- 

 pletely recovered.
