Report of the Committee, consisting of Greneral J. T. Walkeb, General 

 Sir J. H. Lefeot, Professor Sir William Thomson, Mr. Francis 

 Galton, Mr. Alex. Buchan, Mr. J. Y. Buchanan, Dr. John 

 Murray, Mr. H. W. Bates, aucZMr. E. G. Ravenstein {Secretary), 

 appointed for the pui^ose of taking into consideration the 

 Combination of the Ordnance and Admiralty Surveys, and the 

 Production of a Bathy-hypsographical Map of the British 

 Isles. 



1. The Committee consider that the production of a plain outline map of 

 the British Isles and surrounding seas, on a scale of 1 : 200000 (about 

 three miles to the inch) would be desirable. 



Rivers, and such other physical features as can be shown in outline, to 

 be marked distinctly. No hill-shading to be introduced. Roads, railways, 

 towns, &c., to be indicated faintly, and merely for the purpose of identi- 

 fying localities. Principal heights and depths above and below the datum 

 level of the Ordnance Survey of Great Britain to be inserted. 



Contours to be drawn at intervals of 200 feet, with subsidiary contours 

 where they are necessary, to give expression to the features of the 



ground. 



Incidental features, such as cliflPs, &c., to be marked. 

 The map to be tinted according to height. 



2. A grant of 25Z. to be applied for in order that a specimen sheet of 

 the map may be prepared. 



3. The Clyde Trustees to be approached, with a view to their under- 

 taking the preparation of a similar map of the Clyde estuary on a suitably 

 larger scale. 



Other harbour boards to be similarly approached. 



4. The Committee anticipate that, being provided with maps of this 

 character as specimens of what is required to supply a national want, 

 the Association may be in a better position than at present to move the 

 Government to undertake the preparation of a similar map of the whole 

 of the United Kingdom, based mainly upon the extensive data already 

 available in the archives of the Ordnance Survey and the Admiralty. 



Report of the Committee, consisting of Sir Joseph D. Hooker, Sir 

 George Nares, Mr. John Murray, General J. T. Walker, 

 Admiral Sir Leopold McClintock, Mr. Clements Markham, and 

 Admiral Sir Erasmus Ommanney {Secretary), appointed for the 

 purpose of draiving attention to the desirability of further 

 research in the Antarctic Regions. 



YouE Committee, after having given full consideration to the great 

 importance of effecting a further exploration of the Antarctic Polar Sea, 

 desire, in the first place, to.express their opinion that it would be most 

 essential, before approaching H.M. Government with the view of urging 

 the expediency of equipping such a naval expedition as would be
