British Association. — Committee on Steam-ship Performance. 



19 Salisbury Street, Strand, London, W.C. 

 November 21st, 1860. 



Sir, — Enclosed is a Form which the Steam-ship Performance Committee 

 of the British Association hope you will kindly fill up at your convenience, 

 and transmit to me. 



The Committee have apprised the Admiralty of their intention to commu- 

 nicate with such Captains and Engineers of H.M. Ships as may be disposed 

 to assist the British Association in obtaining facts for scientific calculations 

 relating to the Performance of Ships at sea, and have, at their Lordships' 

 request, sent them a copy of the Form. 



The Form proposed is as simple as is consistent with the object of obtaining 

 data necessary for calculation, and the Committee are under the impression 

 that the time required to fill up such Forms cannot interfere with the duties 

 of the respective Oflicers. 



It is, however, to be clearly understood that it is for objects of science 

 alone that the Officers are invited thus to aid the labours of the British Asso- 

 ciation, one of whose fundamental rules is laid down in the following terms : — 



" The object of the Committee is to make pubhc such recorded facts through 

 the medium of the Association, and being accessible to the public in that 

 manner, to bring the greatest amount of science to the solution of the diffi- 

 culties now existing to the scientific improvement of the forms of vessels and 

 the qualities of marine engines. They will especially endeavour to guard 

 against information so furnished to them being used in any other way, and 

 they trust they may look for the co-operation of Members of the Yacht Club 

 having steam yachts, of Shipowners, as well as of Builders and Engineers." 



I am, Sir, your obedient Servant, 



C. R. Moorsom, Vice-Admiral and Chairman.
