form. The following symptoms have been most frequently 

 observed : Slight shivering, which, however, may pass un- 

 observed, followed by increased heat, a more hurried respira- 

 tion and quicker pulse. The lining membrane of the nostrils 

 assumes a brighter red, becomes congested and generally more 

 dry than natural, a condition, however, which is followed at 

 irregular intervals of from twenty-four to forty-eight hours by 

 a thin watery discharge, that soon takes on a thicker yellow 

 flaky purulent character. The inflammation, following the 

 course of the lining membrane proceeding upward, attacks the 

 frontal sinuses and neighboring parts, as evinced by the 

 drooping head, the swollen eyelids, the slpepy expression ; or 

 proceeding downward, the upper portions of the throat are 

 involved, producing soreness of these parts, recognized at 

 once by the more or less inability to swallow, and accompa- 

 nied by a swelling of the neighboring glands about the jaws. 

 Continuing onwards in some cases, the larynx or upper por- 

 tion of the wind-pipe is attacked, by which a hard dry cough 

 is produced, the inflammation being arrested here ; while in 

 otliers, it attacks the deeper seated portions of the air-pas- 

 sages' and even the tissues of the lungs, producing pneumonia. 

 As the period of debility sets in, which is during the early 

 stages of the disease, generally upon the third or fourth day, 

 the pulse is slower and the appetite is more or less aflfected, 

 according to the severity of the attack. This peculiar debility 

 is a vev}' decided feature of the disease, and has been present 

 to a greater or less extent in every case. The healthy action 

 of the bowels and kidneys is more or less interrupted, and 

 there is an unnatural coldness about the lower extremities^ 

 If the disease tends towards recovery, there is a slow improve- 

 ment in all the symjDtoms. The appetite gradually comes 

 back, the countenance becomes brighter, the temperature of 

 the body more equable, and the cough and soreness of throat 

 much less, although the discharge from the nostrils may not 

 diminish but even increase. On the contrary, if through the se- 

 verity of the attack, or through ill-treatment and bad manage- 

 ment, the disease progresses, the symptoms just mentioned 

 grow worse, the respiration is increased, ther&is great coldness 

 of the extremities, excessive prostration, feeble pulse and death 

 by extension of the inflammation to the lungs ; or where the
