116 DISEASES OF THE RESPIRATORY ORGANS. 



Friedberger and Frohner advise that in all cases where there 

 are symptoms of rabies that the frontal sinuses be examined, as 

 there is often a case where the pentastomum is present and it may 

 produce cerebral symptoms and even death without any marked 

 alteration in the mucous membranes of the nasal passages. At 

 the same time, it is possible to accidentally find a pentastomum in 

 a dog that has died from true rabies. The author may also men- 

 tion that he has found cerebral symptoms in an animal that has 

 been suffering from purulent (non-parasitic) nasal catarrh. 



Therapeutics. Nasal catarrh will generally disappear with- 

 out any special treatment. To protect the neighboring tissue from 

 the excoriation of the tissues caused by the discharge, it is well to 

 keep it clean with tepid water and a little borax, or to coat the 

 part with vaseline or oxide of zinc ointment. In all mucous, 

 purulent, or chronic catarrhs spray the nose with a 2 per cent, 

 solution of creolin, or coat around the nostril with vaseline or oil. 

 In acute catarrh it is best to spray the nostril with an atomizer, 

 using either of the following solutions: creolin, 2 per cent.; car- 

 bolic acid, 2 per cent.; boric acid, 3 per cent. ; the inhalation can 

 be given in the form of warm solutions, allowing the animal to 

 inhale the steam from them by the method described in the treat- 

 ment of Chronic Catarrh of the Larynx, on page 119, or with an 

 atomizer; infusions of chamomile, carbolated water, tar water, and 

 oil of turpentine have been used with gaod results. 



Violent bleeding at the nose can be controlled by injections of 

 cold water or a 3 per cent, solution of chloride of iron into the 

 nostril. It is impossible to place a tampon in the dog's nose that 

 will be efficient on account of the anatomical peculiarities 



When the pentastomum is present the only efficient way to get 

 at it is to trephine the frontal bones so that agents can be injected 

 directly into the location of the parasite. For this operation we 

 would refer you to the text books on surgery. 



DISEASES OP THE LARYNX. 



Acute Laryngeal Catarrh. 

 {Acute Laryngitis.) 



Etiology. The most common cause of catarrh of the larynx 

 is cold; laryngitis rarely originates from direct irritation of agents
