II. Meteoeological Ob-seeyations. 



The several self-recording instruments for the continuous registra- 

 tion respectively of, atmospheric pressure, temperature, and humidity, 

 of wind (direction and velocity), sunshine, and rain have been main- 

 tained in regular operation throughout the year. 



The standard eye observations made five times daily, for the con- 

 trol of the automatic records, have been duly registered through the 

 year, together with the additional daily observation at h. 8 m. p.m. 

 in connexion with the Washington synchronous system. The 

 6 h. 45 m, p.m. observation, for the second synchronous system 

 organized by M. Mascart, Directeur du Bureau Central Meteorologique, 

 Paris, was discontinued on December 31st. 



The tabulation of the meteorological traces has been regularly 

 carried on, and copies of these, as well as of the eye observations, 

 with notes of weather, cloud, and sunshine have been transmitted 

 weekly to the Meteorological Office. 



The following is a summary of the number of meteorological obser- 



vations made during the past year : — 



Readings of standard barometer 1929 



,, dry and wet thermometers 7508 



,, maximum and minimum thermo- 

 meters 2190 



5 , radiation thermometers 750 



,, rain gauges 730 



Cloud and weather observations 2294 



Measurements of barograph curves 9125 



,, dry bulb thermograph curves . . 9125 



,, wet bulb thermograph curves. . 8986 



,, wind (direction and velocity). . 17320 



,, rainfall curves 717 



,, sunshine traces 2149 



In compliance with a request made by the Meteorological Council 

 to the Kew Committee, the Observatories at Aberdeen, Armagh, 

 Falmouth, Glasgow, Oxford (Radcliffe), Stony hurst, and Valencia, 

 have been visited as on former occasions, and their instruments 

 inspected by Mr. Whipple during his vacation. 



With the concurrence of the Meteorological Council, weekly abstracts 

 of the meteorological results have been regularly forwarded to, and 

 published by " The Times," " The Illustrated London News," and 

 " The Torquay Directory," and meteorological data have been supplied 

 to the editor of " Symons's Monthly Meteorological Magazine," the 

 Secretary of the Institute of Mining Engineers, Messrs. Buchan, 

 Eaton, Greaves, Gwilliam, McDonald, Rowland, and others.
