DISEASES OF THE RESPIRATORY ORGANS 



j(>ctions of vinegar and water, equal parts, 3 to 5 per cent, solution of 

 alum, tannin, chloride of iron or antipyrin. Tampons are rather difficult 

 to apply, but if the bleeding is persistent they can be used. Use small 

 pledgets of cotton steeped in chloride of iron, taking care the plug is not 

 pushed in entirely, so that it can be removed later by means of forceps. 

 The best means of applying the tampon is to use the rapid tampon. The 

 so-called internal styptics are useless. The injection of gelatine solution, 

 once so much in vogue, is not now used, as it is dangerous. Anaemia from 

 exposure and persistent epistaxis is considered in the chapter on that 

 subject.

Tumors of the Nasal Cavities. 



These may be indicated by a swelling or alteration of the nostril or 

 the adjacent structures; frequently osteo-sarcomas involve the nasal 

 septum, palate or superior maxilla, the new growth absorbing or dis- 

 turbing the normal anatomy of these structures and carcinomas convert- 

 ing the bones into soft cellular structures. Polyps are sometimes pres- 

 ent and are removed either by tortion or by removing the nasal bone 

 and getting into the nasal cavity. 



Catarrh and Pus in the Frontal Sinuses. 



This may result from traumatisms or from pentastomes (see later) 

 or new formations in the frontal sinuses, as a result of nasal catarrh, 

 indicated by swelling and dulness on percussion of the frontal sinuses 

 (see Fig. 60). Acute catarrh of the frontal sinus may result as a sequel 

 of influenza; as a rule, however, it is spontaneously absorbed. If it is
