OATAKKU. 



Catarrhal Deafness— Hay 



; TREATMENT. 



Sufferers are not generally aware that these 

 diseases are contagious, or that they are due to 

 the presence of living parasites in the lining 

 membrane of the nose and eustachian tubes. 

 Microscopic research, however, has proved this 

 to be a fact, and the result of this discovery is 

 that a simple remedy has been formulated where- 

 by catarrh, catarrhal deafness and hay fever are 

 permanently cured in from one to three simple 

 applications made at home by the patient once 

 in two weeks. 



N.B. — This treatment is not a snuff or an 

 ointment ; both have been discarded by repu- 

 table physicians as injurious. A pamphlet ex- 

 plaining this new treatment is sent free on 

 receipt of stamp to pay postage, by A. H. Dix- 

 on & Son, 337 and 339 West King Street. 

 Toronto, Canada. — Christian Advocate. 



Sufferers from Catarrhal troubles should care- 

 fully read the above.
