saving us two and a half hours' running of engine and dynamo 

 each day, half a ton of coal each week, and our gas bill is re- 

 duced proportionate to the number of lights we are wired for. 

 We have never had the slightest trouble with it, and we have 



only when running ; now the dynamo runs only seven and a half 

 hours each day, furnishing light the whole twenty-four hours 

 where required. 



Among the claims made for these cells are their high eflS- 

 ciency, yielding ninety to ninety-two per cent of the current put 

 into them; their freedom from buckling or breaking, owing to

taken from it its rated capacity every night for the past thirty- 

 three nights, and on Sundays from thirty-three and a third to 

 fifty per cent in excess. ' ' Fonnerly, before the battery was put 

 in, the dynamo ran ten hours daily, furnishing light, of course, 



their peculiar construction; economy in use, as they can be 

 charged in a comparatively short time; their capacity, giving 

 about five hours and a half ampere hours per pound weight ; 

 simplicity of service, not requiring an expert electrician to 

 superintend them; and, lastly, their long life. These batteries 

 are now in use in many parts of the country.

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 ofEurope 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 

 other 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 

 bottle, and the use of which, as statistics prove, 

 has I uined 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.
