194 Report of the Meteorological Committee. [Jan. 20, 



parts and at certain seasons, and the connexion between mist 

 (haze) and African dust. 

 9. The diagrams give a picture of Maury's " wedge-shaped doldrums" 

 which any sailor can understand, and the remarks show the 

 weather experienced in them. 

 In these discussions the object of the Meteorological Office has been to 

 determiue the meteorological statistics of limited portions of the ocean in 

 each separate month by means of results obtained by discussion of 

 original observations extracted from the logs in the Office. 



The scope of these publications is consequently different from that of 

 the charts published by the Admiralty, which aim at giving a general 

 view of what may be expected at each season (three-monthly period) over 

 the Atlantic Ocean, as in the "Pilot" Charts, or the whole navigable 

 globe, as in the "Wind and Current" Charts. 



Of the two investigations in question Capt. Toynbee has given popular 

 accounts in papers read before the Uuited Service Institution (in 1873) 

 and before the British Association (in 1875) respectively. 



The Office having thus completed the examination of the district close 

 to the equator in the Atlantic Ocean, about the most important and 

 iuteresting to the navigator and meteorologist of any region in the world, 

 has commenced the investigation of the meteorology of another great 

 district lying on the highroad between Europe and the Indian and 

 Australian seas, that of the Cape of Good Hope, which will be prose- 

 cuted in due course, the question of the best method of dealing with 

 that district being under consideration. 



Another inquiry of considerable interest, of the same nature as that 

 noted as 0. 13, is being instituted into the wind and weather of the 

 North Atlantic during the month of August 1873. For this the Office 

 has obtained the loan of 280 logs, as will be mentioned later on. 



"While thus working at its own materials the Office has not been 

 neglectful of foreign publications of value bearing on Ocean Meteorology. 

 Three of these have been specially published, in addition to the repro- 

 duction of the Dutch Sea-Temperature Observations for the Atlantic, 

 which have been already mentioned. 



These three are : — 

 N. 0. 4. Eoutes for Steamers from Aden to the Straits of Sunda and 

 back. Translated from a paper by Lieut. J. E. Cornelissen, 

 of the Eoyal Meteorological Institute, Utrecht. 

 N. 0. 5. On the Winds, &c. of the North Atlantic along the Tracks of 

 Steamers between Europe and America. Translated from a 

 paper by Herr von Ereeden, of the Deutsche Seewarte, 

 Hamburg. 

 N. O. 7. Notes on the Eorm of Cyclones in the Southern Indian Ocean. 

 Eeprint of a paper by C. Meldrum, M.A., E.E.A.S., Secretary 

 of the Meteorological Society of the Mauritius.
