368 FEVERS AND THEIR TREATMENT.

 are more persistent, the name influenza is given. After the 

 first few days, the running at the eyes and nose increases, and 

 a cough is almost always present, which symi^toms often persist 

 for two or three weeks, leaving great prostration of strength at 

 the end of that time, and often a chronic cough, which requires 

 careful treatment. 



The cause is to be looked for in some peculiar state of the 

 air, of the nature of which nothing is known at preseni. 



Treatment. — In the early stage, the remedies should be the 

 same as for ordinary or simple " cold." Towards the second 

 week, a cough-bolus (46) or draught (47) will generally be re- 

 quired. When the strength is much reduced after the second 

 week, and the cough is nearly gone, give a tonic pill (62) or 

 mixture (63). Great care should be taken not to bring on a 

 relapse by improper food, or by too early an allowance of ex- 

 ercise. Fresh air is of the utmost importance, but it must be 

 taken at a slow pace, as a gallop will often undo all that has 

 been effected in the way of a cure.
