ON STEAM-SHIP PERFORMANCE. 199 



their sense of the services rendered to the Association by Mr. Henry Wright, 

 their Honorary Secretary, whose untiring energy, indefatigable labours, judg- 

 ment, and discretion, have enabled them to lay this information before the 

 meeting. 



To Mr. Smith, a member of the Committee, their acknowledgements are 

 due, as well for the use of a room in his offices, as for several sources of 

 information opened to them by his influence. 



The Marquis of Stafford, by placing a room in his house at the disposal 

 of the Committee for occasional meetings, has contributed materially to the 

 personal convenience of the members.

It was originally intended to institute inquiries, not only in London and its 

 vicinity, but also in Glasgow, Liverpool, Hull, Bristol, Southampton, New- 

 castle-on-Tyne, &c, and for this purpose it would have been necessary to 

 defray the expenses of an agent to conduct the inquiry ; but the shortness 

 of the session, together with the extended field which London presents, ren- 

 dered that course impracticable. 



Your Committee feel, that a beginning having thus been made towards the 

 means of a scientific investigation of the performance of ships under differ- 

 ing conditions at sea and in smooth water, it would ill become the British 

 Association for the Advancement of Science to drop the question, although 

 expense as well as trouble is involved in its successful pursuit. 



They recommend the reappointment of a Committee, with a renewal of 

 the grant, and with power to remunerate a clerk for such services as cannot 

 be undertaken by any of its members. 



On behalf of the Committee, 



C. R. Moorsom, Vice- Admiral, 

 19 Salisbury Street, Strand, London, Chairman. 



June 13th, 1860. 



Note. — Since the above Report was written, and whilst in the press, infor- 

 mation was forwarded to the Committee which has enabled them to compile the 

 Table given in the Supplementary Appendix, showing very interesting com- 

 parative results of two vessels, the 'Lima' and ' Bogota,' when fitted with 

 different systems of machinery. The Table shows the results of perform- 

 ances on trial of these vessels when fitted with single-cylinder engines, and 

 also at sea on a voyage of upwards of 6000 miles ; also their performances 

 when fitted with double-cylinder engines.
