The observations wore written down at the screens on a piece of paper, printed for the purpose, secured 

 to a board, and on the arrival of the observer on board were copied into the rough book. 



The time of observations was every two hours, local mean time, and every cure was taken that the 

 observer should leave the ship punctually. He was mstrm -ted to take the barometer first, then to read

the dry- and wet-bulb and minimum thermometers, resetting the latter; next to ascertain the direction 

 and force of the wind by Beaufort scale, reading the Eobinson anemometer and the " small Dines," and, 

 lastly, to observe the clouds and to make any general remarks that might lie called for. 



As the work of Meteorological Observations cannot depend wholly on one person, my thanks are due to 

 one and all for their very great assistance. 



BAROMETER. 



Throughout the voyage from England until we got into Winter Quarters in Latitude 77 r 50' S. the 

 barometers were hung in the entrance to the Ward-room lobby; the cistern being about 9 feet above the 

 sea-level. 



Before our arrival at Cape Town, barometer No. 592 was broken and was replaced by No. 2244, kindly 

 given us by the Cape Town Observatory, and always used at sea. When we reached Winter Quarters 

 the three barometers No. 915, No. 2244, No. 612 were hung in the Magnetic House, which was situated on 

 the upper deck, below the bridge and above the mess-deck. 



Two-hourly observations were taken with No. 915 and attached thermometer and at noon, and 

 throughout the first year at other times. Comparison observations were made with the other two 

 Ijarometers, but owing to the attached thermometers on these instruments not registering below zero, 

 many observations were taken without the attached thermometer. 



It will be noticed that there are large fluctuations of the attached thermometer on No. 915. This 

 variation was due to the door having been at times left open between the observations, and when it was at
