REPORT OF THE SECRETARY GENER/ily lOI 



ArTICIvE 3. 

 The Second Pan American Scientific Congress recommends that the 

 American Republics undertake as soon as practicable — 



(a) Accurate geodetic measurements which may serve to determine 



limits, national and international, and to contribute to the 

 discovery of the true shape of our planet ; 



(b) Magnetic measurements of their respective areas, and the estab- 



lishment of several permanent magnetic observatories in 

 which it may be possible to carry on during long periods of 

 time observations concerning the secular variation of the 

 magnetic elements of the earth; 



(c) To extend their gravimetric measures, obtained by means of 



the pendulum, to those regions where such measurements 

 have not been undertaken, in order to obtain more informa- 

 tion to determine the true shape of the surface and the dis- 

 tribution of the terrestrial mass. 



Article 4. 

 The Second Pan American Scientific Congress recommends that — 



The Nations of the American Continent establish, by means of their 

 offices of geodesy or by committees appointed for that pur- 

 pose, an international triangulation; 

 The Governments of the American Nations reach an agreement for 

 the purpose of creating an office or congress of cartography 

 and geography. 



Article 5. 



The Second Pan American Scientific Congress recommends that — 



Proper steps and measures be taken to bring about in the American 

 Republics a general use of the metric system of weights and 

 measures, in the press, magazines, newspapers, and periodicals, 

 in educational and scientific work, in the industries, in com- 

 merce, in transportation, and in all the activities of the differ- 

 ent Governments. 



Article 6. 



The Second Pan American Scientific Congress — 



Confirms the resolution recommended to the American Republics by 

 the First Pan American Scientific Congress regarding the 

 installation of meteorological organizations to serve as a basis 

 for the establishment of a Pan American meteorological serv- 

 ice, and expresses the desire that the Republics not yet pos- 

 sessing organized meteorological services establish such as 

 soon as may be practicable.
