Prof. JANSSEN, Delegate of France. When my honorable colleague, Commander SAMPSON, reads the remarks which I have just made, he will see that I have very fully shown what characterizes a neutral or geographical meridian, as contradistinguished from those meridians which, passing through capitals and observatories of different countries, bear the names of nations, whilst geographical meridians bear geographical names, such as the meridian of Ferro, of the Azores, Behring's Strait, &c. Of course it would be necessary to connect the places selected with observatories, either by calculation or in some other effective manner. I said all this a few moments ago. Mr. RUTHERFURD, Delegate of the United States, then remarked that in addition to what had been said he would merely call attention to the fact that after that neutral point had been established it would cease to be a neutral meridian; that if the Azores be chosen they belong to Portugal, and he did not know any island in the Pacific which would serve the purpose, and at the same time not be subject to this objection; that perhaps Behring's Strait, mentioned by the French Delegate, might be less objectionable than any other place. He added that it is absolutely necessary that there should be some means of determining the difference between this adopted place and the other places, or else no use could be made of it. We must know how far other places are from the prime meridian, and for that reason it is necessary that it should be on land. Now, that land must belong to some country, and after we have fixed upon it it would cease to be a neutral meridian, and it would have to be connected by telegraphic wires with all the great observatories in the world. Prof. JANSSEN, Delegate of France. My honorable friend, Mr. RUTHERFURD, says that from the time the prime meridian was chosen it would cease to be neutral. I reply that he confounds a scientific principle with a question of property in the soil. If, for reasons of a geographical nature, we should fix upon a point in the Azores, that meridian would be neutral, because it would have been chosen on scientific grounds alone. The equator is neutral because geographical conditions give it that character; and, nevertheless, the countries along it belong to various nations, do they not? As to the manner of connecting the prime meridian with the system of observatories, I have already explained how this may be done in my former speech.
