258 PROCEEDINGS OF SECTION A. 



XXIV. That the following subjects for experiment be referred to 

 each member of the C'onference, for future consideration 

 and report : — 



1. Shade temperature. 



2. Swinging thermometer and thermometer sheds in 



use. 



3. Standards to be swung with 2ft. 6in. string during 



sunshine and after sunset. 



4. Observations to determine the difference in 



hvimidity, by self-registering maximum and 

 minimum thermometers, and by other methods. 



5. The best method of measuring the velocity and 



pressure of wind. 



6. Whether any better method than black bulb ther- 



mometers can be devised for measuring the 

 direct effect of the sun. 



7. As to the best method of determining spontaneous 



evaporation. 

 XXV. That, as investigation of the Newcastle tide-gauges has 

 shown that such instruments give valuable indications 

 of distant earthquakes, gales, and sea disturbances, it is 

 desirable, in the opinion of the Conference, that self- 

 registering tide-gauges be established in as many con- 

 venient jilaces as possible on the coast, in connection 

 with the meteorological departments of tlie different 

 colonies. 

 XXVI. That the foregoing minutes be adopted as the report of 

 this Conference on the various matters referred to it, 

 and that the chairman be requested to report to the 

 Government of New South Wales. 

 A second conference was held at Melbourne in April, 1881, the 

 same gentlemen being present. Among other resolutions, it was 

 agreed — 



That daily isobar maps, on the system adopted in Europe and 

 America, should be issued by the head office in each colony. 

 That, with a view to the instrumental readings being referred to 

 one uniform standard, a complete set of standard instru- 

 ments, viz., barometer, thermometer, solar thermometer, 

 and anemometer, be purchased for circulation between the 

 then four chief stations, viz., Melbourne, Sydney, Welling- 

 ton, and Adelaide. 

 That the New South Wales Government should move the 

 Queensland Government to co-operate by transmitting daily 

 reports from Brisbane, Rockhampton, Cooktown, Norman- 

 ton, and Cloncurry. 

 The Governments of New Caledonia and Fiji were also to be 

 moved to have regular observations taken and published, on 

 the Australian system.
