ULCERATIONS IN THE NASAL CAVITIES. 59 
CHAPTER IV. 
INFLUENZA. 
INFLUENZA, as it generally manifests itself, is a combination of coryza and 
bronchitis, attended by more severe constitutional disturbance than usually 
exists when these diseases occur together. For instance, there is much depres- 
sion, which often in time becomes great prostration, soreness throughout the 
body and limbs sufficient to suggest rheumatism, complete loss of appetite, and 
high fever. In fact, this disease is a veritable acute catarrh of considerable 
extent and great intensity; and it might, without impropriety, be called a “hard 
cold all over.” 
It runs the course of the nasal and bronchial affections named, and their 
various changes characterize it; but while in some instances recovery takes 
place as speedily in this disease as in them, as a rule it is slower, and may be 
delayed for several weeks, or possibly months. 
Although the etiology is still uncertain, considering that it appears as an 
epidemic and is not dependent on bad weather or exposure, beyond doubt its 
direct cause is a germ. ; 
It only rarely attacks dogs. When one falls a victim to it, others in the neigh- 
borhood are sure to be attacked ; consequently its real character soon becomes 
known, and there is but slight danger of its being mistaken for pneumonia, to 
which, from its high fever and great prostration, it bears some resemblance. 
But seldom does recovery fail to occur; and in fatal cases there is almost 
always some serious complication, and generally pneumonia. 
The best medicinal remedy, efficacy and safety combined, is the sulphate of 
quinine; and this should be administered in the same doses, repeated as often, 
and after the same intervals, as in pneumonia. Reliance should afterward be 
on good nursing, stimulants being given if there is very great prostration, but 
not otherwise. To feed generously from the first, employing force if necessary, 
should also be the rule in very severe cases. 
ULCERATIONS IN THE NASAL CAVITIES. 
When ulcers form in the nasal cavities the affection is often mistaken for 
ozena, to which, however, it is not related, notwithstanding in some of its most
