ing countries was made in the first instance 

 for five years only, in case the publication of 

 the catalogue should fail financially or in 

 other ways. It was also decided to spend 

 £100 in making the catalogue known, and to 

 take steps to invite the cooperation of other 

 counti'ies not yet represented on the council, 

 e. g., Spain, the Balkan States, South Ameri- 

 can Republics, etc. 



The proposal to publish additional volumes 

 upon, a, medicine and surgery; &, agriculture, 

 horticulture and forestry; c, technology (vari- 

 ous branches) was discussed, and it was de- 

 cided that the executive coramittee should 

 take the suggestion into fuller consideration 

 and bring it under the notice of the inter- 

 national convention in July, 1905. It was 

 also resolved that all alterations in the 

 schedules should be collected and edited by the 

 central bureau prior to submission to the 

 regional bureaus for their opinions, and that 

 the schemes should be edited by a special com- 

 mittee before being submitted to the inter- 

 national convention.

INAUGURATION OF THE MAGNETIC SUR- 

 VEY OF THE NORTH PACIFIC OCEAN. 



As announced in a previous issue of Sci- 

 ence, the brig Galilee of San Francisco, a 

 wooden sailing vessel, built in 1891^ of length 

 132.5 feet, breadth 33.5 feet, depth 13.7 feet, 

 displacement about 600 tons, has been char- 

 tered by the department of terrestrial mag- 

 netism of the Carnegie Institution of Wash- 

 ington for the purpose of making a magnetic 

 survey of the North Pacific Ocean. After the 

 various necessary alterations, e. g., substitu- 

 tion of the steel rigging by hemp rigging, etc., 

 were made, the vessel entered upon her duties 

 early in August. Magnetic observations were 

 made at various places on the shores around 

 San Francisco Bay and the most suitable 

 place for ' swinging ship ' by their aid de- 

 termined. The ship was ' swung ' with the 

 aid of a tug on August 2, 3 and 4 in San 

 Francisco Bay between Goat Island and 

 Berkeley, California, and the various devia- 

 tion coefficients were determined. 



On August 5, the Galilee sailed from San 



Francisco, secured magnetic observations 

 daily to a greater or less extent according to 

 conditions of the weather and sea, ' swung ' 

 twice vmder sail, and arrived at San Diego, 

 August 12. This first short cruise was an 

 experimental one, various instruments and 

 methods having been subjected to trials under 

 the direction of the writer, who accompanied 

 the expedition as far as San Diego. The de- 

 flection apparatus devised by the writer for 

 deterraining horizontal intensity has proved 

 successful. In a . future paper the methods, 

 instruments and results will be more fully 

 described. 



After further alterations had been made at 

 San Diego, and the deviation coefficients hav- 

 ing been redetermined, the Galilee again set 

 sail, on September 1, this time for the Hawai- 

 ian and Midway Islands and is expected to 

 return to San Francisco about December 1. 

 After these two experimental voyages, she is 

 to sail from San Francisco early in 1906 on a 

 more lengthy cruise — one embracing the en- 

 tire circuit of the North Pacific Ocean. 



The scientific personnel at present consists 

 of Mr. J. F. Pratt, commander; Dr. J. Hobart 

 Egbert, surgeon and magnetic observer ; Mr. J, 

 P. Ault, magnetic observer, and Mr. P. C. 

 Whitney, magnetic observer and watch officer. 

 The sailing master is Captain J. T. Hayes, 

 who has made some record sailing trips in the 

 Galilee — one a voyage of 3,000 miles from the 

 South Pacific Islands to San Francisco in 

 fifteen days and having made as much as 308 

 miles in one day.

EXPERIMENTAL STUDIES IN YELLOW 

 FEVER AND MALARIA AT VERA CRUZ. 



The U. S. Public Health and Marine Hos- 

 pital Service has published a bulletin on the 

 experimental work done by assistant surgeons 

 M. J. Eosenau, Herman B. Parker, Edward 

 Francis and George E. Beyer, the conclusions 

 of which are as follows : The cause of yellow 

 fever is not known. The Myxococcidium
