acter of a Russian village, which touches the rest of the world 

 ooly when the few Jewish traders come to it to take provisions in 

 exchange for their wares. Each is the serf of all, and escape to 

 the city, for reasons which are explained in the paper, offers no 

 relief. At a time when the great empire is driving Jews from 

 their homes, it will be of general interest to learn something of its 

 own industrial and political unit ("Publication of the American 

 Academy of Political and Social Science, No. 34." Station B, 

 Philadelphia. 50 cents). 



— The American Academy of Political and Social Science, with 

 headquarters at Philadelphia, has issued in a little over a year 

 over thirty papers in its regular publications, each dealing with 

 some important topic in its field of investigation. Most of these 

 have been of an historical or theoretical character. The last one 

 which has appeared, however, is entirely practical in character, 

 and will be of value to all who have occasion to use the statistical 

 « publications of any department of the United States government. 



The federal census, statistics of commerce, statistics of production, 

 statistics of education, finance statistics, railroad statistics, and 

 statistics of labor are discussed briefly in turn, and the work of the 

 different bureaus which issue statistical publications of any de- 

 scription is in so far described. The author is William F. Wil- 

 loughby of the Department of Labor ("Publications of the Ameri- 

 can Academy of Political and Social Science, No. 35." Station B, 

 Philadelphia. 50 cents). 



— -According to the Japanese Gazette, ipiiuted in Yokohama, 

 " during the month of June there were 5,575 persons who took 

 books from the Tokyo Free Library, nearly all of them in the 

 Japanese and Chinese languages. Among the 36,687 volumes 

 drawn, 7,483 were books of history, biography, and geography, 

 6,753 of law and politics, 6,600 pf literature and language, 5,877 

 of natural philosophy and medicine, 4,174 of engineering, the arts, 

 and industries, 2,087 of philosophy and education, and the rest 

 were of a miscellaneous kind." 



Exhaustion 



The phosphates of the system 

 are consumed with every effort, 

 and exhaustion usually indicates 

 a lack of supply. The Acid 

 Phosphate supplies the phos- 

 phates, thereby relieving exhaus- 

 tion, and increasing the capacity 

 for labor. Pleasant to the taste. 



Dr. A. N. Kbout, Van Wert, 0., says: 



' ' Decidedly beneficial in nervous exhaus- 

 tion." 



Dr. S. T. Newman, St. Louis, Mo., says; 



' ' A remedy of great service in many 

 forms of exhaustion."
