SCIENCE. 



335 



dissertations in political science." The opening number of the 

 series is a paper on "The Divorce Problem," by Walter F. Will- 

 cox, and is in the main a compilation of statistical matter taken 

 from the report on divorce made by Carroll D. Wright of the La- 

 bor Bureau. Various remarks by the author are interspersed, 

 and at the close he considers briefly the causes that have made 

 divorce so common in this country, and offers a few suggestions 

 as to the remedy. Most of his remarks are sensible, but there is 

 nothing new in them, and those who know what has been writ- 

 ten on the subject by others will get no particular help from Mr. 

 Willcox. The style of the pamphlet is similar to that of most 

 other college publications, and indicates that the study of litera- 

 ture in the colleges is not what it should be. 



"The Evolution of Wool Spinning and Weaving" will be de- 

 scribed by S. N. D. North in the July Popular Science Monthly. 

 This is the sixth paper in that periodical's illustrated series on the 

 development of American industries since Columbus, and covers 



a notably interesting group of inventive labors. Under the title 

 of " Man and the Glacial Period," Professor G. Frederick Wright 

 will contribute to the same number a record of the important facts 

 that have come to light in the last two years bearing upon the 

 connection of man with the ice age in North America. The pa- 

 per will be illustrated. " Sanitary Improvement in New York 

 during the Last Quarter of a Century," by Gen. Emmons Clark, 

 who has been secretary of the New York Board of Health during 

 the whole twenty-five years that it has been in existence; " Pol- 

 len: its Development and Use," by Professor Joseph F. James; 

 "Colors of Letters," by David Starr Jordan, the newly appointed 

 president of Stanford University; and an account of "Our Agri- 

 cultural Experiment Stations," by Professor Charles L. Parsons, 

 will add to the completeness of the number. 



— The Home Journal, in its issue of June 10, publishes a double 

 number, consisting of sixteen large pages. The paper includes, 

 besides its usual literary features, a " Summer Resort Guide." 



Exha^fion 



floi'sforJ's Acid Plospliate, 



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. Kkout, 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."
