There are emttlsions and einulsions, '

 which masquerades as cream. Try as j

 so disguise their cod liver oil as to make 

 it palatable to sensitive stomaetis. Scott's ,

A New Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? There is a new departure in 

 the treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists of Europe and America, and bringing them 

 within the reach of all. For instance, the treat- 

 ment pursued by special physicians who treat 

 indigestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 olher physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys, 

 female weakness, rheumatism and nervous de- 

 bility. 



This new method of " one remedy for one 

 disease" must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure every ill out of a single 

 bott'le, and the use of which, as statistics prove, 

 has ruined more stomachs than alcohol. A cir- 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro- 

 prietors.
