The TRACES of the following self-recording instruments : 



Barograph. From December 2, 1901, till March 28, 1904, complete, generally in duplicate. 

 Thermograph. From December 2, 1901, till February 29, 1904, complete, generally in duplicate. 

 Hygrogmph. Nearly complete, sometimes in duplicate, but traces often unsatisfactory. 

 Sunshine Recorder. Some days missing. 

 Dines' Anemograph. Incomplete and of doubtful value. 



II. Auxiliary Daily Observations at Noon G.M.T, 



(a) LAND OBSERVATIONS. Transcripts, daily charts, and traces of self-recording instruments from the 



Argentine Republic, Cape of Good Hope (Cape Town), Mauritius, Australia (Perth and 

 Sydney), New Zealand (Wellington), Falkland Isles (Cape Pembroke), collected in response to 

 a circular of the International Antarctic Committee and of the Royal Society. 



(b) MARINE OBSERVATIONS. 30,200 days' readings between 1st October, 1901, and 31st March, 1904, 



in special or ordinary ship's logs. Collected by the Meteorological Office. 



For the explanation of local circumstances and conditions we were dependent upon Lieutenant Rovns' 

 'Notes' and the Narrative of the Expedition, published by Smith, Elder, and Co. for 

 Captain SCOTT. An occasional visit from one or other of the members of the Expedition 

 supplemented to some extent the information from other sources. 



The Meteorological Council, whose staff was already overloaded with material collected in the ordinary 

 course of office business, were not prepared to accept responsibilty for this additional volume of data. 

 Undoubtedly, had circumstances permitted, it would have been advisable to detail a special staff for 

 the work under the control of a competent meteorologist, who would have been responsible for the issue of 

 a complete report upon the observations. There were two objections to this obviously desirable course. 

 First, competent meteorologists in this country were all too fully occupied to be able to devote the 

 necessary time to the supervision ; and, secondly, a meteorological staff requires some training and 

 experience for which, in this case, no provision was available. 



It was eventually decided that the work should be done in the Meteorological Office under my general 

 supervision, the office staff being increased for the time being by a few additional clerks in order to 

 set free experienced tabulators and computers for the work of critical examination. The expense was 

 charged against a guarantee of the Royal Geographical Society, but ultimately placed upon the funds of 

 the Expedition. 



Scientific control was provided for by a Committee appointed by the Royal Society, consisting of 

 Mr. J. Y. BUCHANAN, Dr. C. CHREE, Mr. W. H. DINES, Admiral FIELD, Dr. GLAZEBROOK, Sir J. MURRAY, 

 Dr. W. N. SHAW, Captain TIZARD, Mr. C. T. R. WILSON, Mr. H. N. DICKSON, Mr. FERRAR, Mr. A. J. 

 HERBERTSON, Dr. H. R. MILL, and Lieutenant ROYDS. 



PRESENTATION OF THE RESULTS. 



The data of the observations at Winter Quarters and on the sledge journeys have been carefully 

 examined and are printed in extenso, pp. 17 to 364, with maps prepared by Lieutenant MuLOCK for the 

 Royal Geographical Society to illustrate the geographical positions. 



The two-hourly values have also been reproduced, arranged in the form adopted by international 

 agreement for the publication of results from stations of the first order, pp. 365 to 406 ; and a summary of 

 monthly results in the form usual for stations of the second order is given on p. 408. Readers who wish 

 to obtain a conspectus of the salient meteorological features of the Winter Quarters of the " Discovery " 

 will find it in this table. Tables of results for other expeditions are given for the purpose of comparison. 



The introduction, which gives an account of the exposure of the instruments, is by Lieutenant C. W. R. 

 ROYDS, R.N., who was in charge of the meteorological work of the Expedition. Various members of the
