national sanitary commission to be composed of 

 not more than five members of each government, 

 this commission to hold annual or periodical

 meetings it would discuss and make recom-

 of improving them. 



The Bibliogi'aphical Society of Chicago, an 

 organization founded ' to encourage and pro- 

 mote bibliographical study and research,' has 

 requested the Committee on Education of the 

 St. Louis Exposition to appoint a Commissioner 

 of Bibliography for the Louisiana Purchase 

 , Exposition whose •duties shall be : (1) To have 

 supervivsion and final control of all bibliograph- 

 ical publications that may be issued in connec-

 the Institute has been divided into four sections 

 by which the following topics will be investi- 

 gated : 



SECTION A. — HI9T0KY AND STATISTICS. 



Topic 1. The early history of the disease. 



Topic 3. History of recent epidemics (since 1850). 



Topic 4. Relation to modern sanitation, especially 

 paving, drainage, etc., in cities. 



Topic 5. Why did not New Orleans have it in 

 early times vphile Boston did ? 



Topic 6. Mortality statistics. 



Topic 7. Maps showing yelloT^ fever zones. 



Topic 8. Maps showing the infectible territory in 

 the United States. 



SECTION B. — ETIOLOGY. 



Topic 1. The cause of the disease. 



SECTION C— TRANSMISSION. 



Topic 1. The transmission of the disease by the 

 mosquito. 



Topic 2. Can any other mosquito than the Ste- 

 gomya fasciata carry the infection? 



Topic 3. Is the progeny of the mosquito also in- 

 fected ? 



Topic 4. How many generations ? 



Topic 5. Can the mosquito become infected by any 

 other means than by sucking the blood of a patient 

 sick with the disease ? 



Topic 6. Can the mosquito become infected by 

 contact with the dried blood discharges or other in- 

 fected materials upon fomites ? 



Topic 7. Can the disease be transmitted by any 

 other means than through the mosquito? 



Topic 8. Can the disease be conveyed by fomites, 

 or through the air, soil or water ? 



Topic 9. The geographical distribution of Stego- 

 mya fasciata in relation to the disease. 



Topic 10. Is the immunity enjoyed by certain 

 localities due to the absence of this variety of mos- 

 quito ? 



Topic 11. A study of the life and habits of the 

 Stego-.nya and allied species, especially with a view 

 to their extermination. 



SECTION D.— QUARANTINE AND TREATMENT. 



Topic 1. Is disinfection of baggage necessary to 

 prevent the spread of the disease ?
