ters what he calls " natural monopolies," or, in other words, that 

 it increases the cost of food and the^rent of land. His arguments 

 in support of this position are strangely inconclusive, and the 

 whole theory is upset by the example of the English corn-laws. 

 It was not free trade, but protection, that made food dear in Eng- 

 land; and it would have become still dearer if the corn laws had 

 not been repealed. Professor Patten advocates protectionism, not 

 as a temporary expedient, but as "part of a fixed national policy" 

 (p. 8). He maintains that "our economic conditions are so dif- 

 ferent from those of any foreign nation that an American indus- 

 trial policy must be of a distinct tyi^e from that of other nations" 

 (p. 14); and he thinks it best for us to "isolate ourselves" as 

 much as possible from the nations of Europe. Such are some of 

 the salient points of the woi-k; but we doubt if they will have 

 much influence on jiublic opinion.

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 

 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 IVledlcines which 

 are guaranteed to cure every ill out of a single 

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

 /las rtcined 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.
