 recommended CROSBY'S VITALIZED PHOSPHITES, for the relief of Nervous Derange- 

 ments, Brain Weariness, Dyspepsia, and Debility.

ONE LANGUAGE FOR THE WHOLE WORLD 



" WORLD ENGLISH," just now ready, is, as its 

 name implies, a new form of tlie Englisfi language for inter- 

 national communication. 



It is the invention of Prof. Alexander IWelville Bell, the 

 renowned author of "Visible Speech," and is so simple, and at 

 the same time so practicable, that it cannot fail of soon being 

 generally accepted as the Universal Lang uage. 



Its great superiority over "Volapuk," or any other 

 artificial language, may readily be seen by a comparison of the 

 two systems. 



Ex-President Andrew D. White, of Cornell University, 

 says : "I believe that the highest interests of Christian civil- 

 ization and of humanity would be served by its adoption 

 China and Japan would be made English-speaking peoples 

 within fifty years, and so brought within the range of Chris- 

 tianizing and civilizing ideas, in the largest sense. All exist- 

 ing miss'onary work is trivial as compared wiih this. For 

 your sys' em would throw wide open those vast countries, as, 

 indeed, all the countrie'i of the world, to the whole current of 

 English and American thought."
