POPULAR MISCELLANY. 



Meeting of the Aniericaa Association. 



The forty- third meeting of the American 

 Association for the Advancement of Science 

 will be held in Brooklyn, N. Y., August 15th 

 to 24th. The names of the officers were 

 given in The Popular Science Monthly for 

 October, 1893. The rooms of the Polytech- 

 nic Institute, the Packer Institute, the Art 

 Association, the Long Island Historical So- 

 ciety, and the Academy of Music have been 

 offered for the use of the association. The 

 meetings will be held mainly in the build- 

 ings of the Polytechnic and Packer Insti- 

 tutes. The headquarters of the association 

 will be at the St. George Hotel, Clark Street. 

 The Ladies' Reception will be given August 

 16th. An unusually varied and attractive 

 list of excursions is offered, including free 

 excursions to Long Branch ; Cold Spring 

 Harbor, Long Island, where are the Biologi- 

 cal Laboratory of the Brooklyn Institute and 

 the station of the New York Fish Commis- 

 sion ; up the Hudson to West Point and re- 

 turn ; and around the harbor ; geological 

 excursions to sis points of interest ; miner- 

 alogical excursions to six points ; botanical

 General Association will be held before and

Classes in Economics. Instruction in the 

 Department of Economics in the School of 

 Applied Ethics, Plymouth, Mass., during the 

 session July 12 to August 15, 1894, will be de- 

 voted to a discussion of the relation between 

 economics and social progress. The idea 

 which underlies it is, that all phases of social 

 activity and living are necessarily bound to- 

 gether, and consequently that no problem in 

 which human relations are a prominent fac- 

 tor, whether theoretical or practical, can be 

 properly understood, except it be studied in 

 the light of some comprehensive theory of 

 social development. The same general pur- 

 pose will be recognized in the adjustment of 

 courses in the other departments of the 

 school, which include those of History of 

 Religious and Applied Ethics. The scheme 

 of lectures includes courses by Prof. H. C. 

 Adams, director, on the Historical Basis of 

 Modern Industries, Relation of Economic 

 Theory to Social Progress, and The Trans- 

 portation Problem ; by Prof. J. B. Clark, on 

 The Ethics and the Economics of Distribu- 

 tion ; by Prof. R. Mayo-Smith, on Ethnical 

 Basis for Social Progress in the United 

 States ; by President E. B. Andrews, on 

 Civilization and Money ; their Relation il- 

 lustrated by the History of Money ; by Prof. 

 F. H. Giddings, on The Social Functions of 

 Wealth ; by Prof. J. W. Jeuks, on the Re- 

 lation of Political and Industrial Reform; 

 and by Dr. E. R. L. Gould on Practical 

 Problems in Municipal Economy. 



Tlie Benefits of Sanitation, A paper on 

 The Achievements of Sanitation measured by 

 Vital Statistics, by George E. Willetts, of 

 Lansing, Mich., contains some suggestive 

 data bearing on the usefulness of modern 

 sanitation. Having sought for some com- 

 pilation of death-rates from a number of the 

 principal diseases reaching back for so long 

 a period as to tell a connected story concern- 

 ing such diseases, without being able to find 

 it, Mr. Willetts carefully worked out the 

 subject himself from selected data relating 

 to mortality from fevers, cholera, consump- 

 tion, smallpox, and all causes as recorded
