If the resolution for a neutral meridian had been adopted, all nations would have to make the sacrifice necessary for a change to a meridian not actually determined, and the relations of which could not be so convenient with those meridians already adopted as are the relations between the meridians now in use with that of Greenwich. It does seem to me that if the Delegates of France could see their way to adopt this resolution, they would have no occasion whatever to regret it. I sympathize deeply with what has been said in regard to a common metrical system. I have a very strong opinion upon this subject, which I will not express, however, if it meets any objection from the Chair; but it seems to me that England is making a sacrifice in not adopting the metrical system. The question, however, cannot be put in that way. We are not here to consider whether England would gain or lose by adopting the metrical system. That is not the way to view this question at all, because whether England should adopt the metrical system is a matter for its own convenience and use, and whether it adopts it or not, other nations are not affected by its course. It would not at all be for the benefit or the reverse of other nations. The PRESIDENT. The Chair would be very glad to hear Sir WM. THOMSON'S views on this subject if it were before the Conference for discussion, but it is not. Sir WILLIAM THOMSON. I beg pardon for having mentioned it. I would repeat that the adoption of the meridian of Greenwich is one of convenience. The difference of other meridians from it is readily ascertained, and therefore it seems to me that the minimum of trouble will be entailed on the world by the general adoption of the meridian of Greenwich. This would require the minimum of change, and, furthermore, the changes which would be necessary are already wholly ascertained. I would inquire of the Chair whether it would be in order for me to allude to the resolutions number 2 and 3, which have been read? The PRESIDENT. I think that we must confine ourselves to the subject immediately under discussion--the adoption of a prime meridian. Sir WILLIAM THOMSON. Then I have only to thank you and the Delegates for allowing me to speak, and to express my very strong approbation of the resolution that has been proposed. Sir F. J. O. EVANS, Delegate of Great Britain, then made the following remarks:
