Mr. JANSSEN, Delegate of France, said:  We do not put forward the meridian of the observatory of Paris as that to be chosen for the prime meridian; but if it were chosen, and we wished to compare it with that of Greenwich as to the accuracy with which it is actually connected with the other observatories of Europe, it would not lose by the comparison.  The latest observations of the differences of longitude made by electricity by the Bureau of Longitudes of France and our officers have given very remarkable results of great accuracy.  It is well known that what is important for a starting point in reckoning longitude is, above all things, that it should be accurately connected with points whose positions have been precisely fixed, such as the great observatories.  There is, therefore, a slight confusion on the part of my eminent colleague, namely, that of not distinguishing between the conditions which require the exact connection of the starting point of longitudes with observatories, and the merits of the position of such a point in an astronomical aspect, which is here a matter of secondary importance.

Mr. LEFAIVRE, Delegate of France, said that he did not not know if his observation was well founded, but it seemed to him that what the Delegates of France had proposed had not been contested, but that the arguments used had rather been those in favor of the adoption of the meridian of Greenwich.

Mr. RUTHERFURD, Delegate of the United States, said that the observations which he had made were merely to be regarded as a negative of the proposition made by the Delegates of France, and not as a statement of the arguments in favor of the adoption of Greenwich.

The PRESIDENT said that the remarks of the Delegate of the United States were not out of order, inasmuch as they were intended to combat the proposition brought forward by the Delegate of France.

Mr. JANSSEN, Delegate of France, then spoke as follows: 

GENTLEMEN:  At the last session, when a proposition was made by my eminent colleague and friend, Mr. RUTHERFURD, to discuss and vote upon the adoption of the meridian of Greenwich as the common prime meridian, I thought it necessary to say that the proposal appeared to me prematurely made, and that we could not agree to the discussion proceeding in that manner.  Mr. RUTHERFURD has informed me that he would withdraw his proposition for the present, in order to permit me to direct the discussion, in the first place, to the principle which should direct the choice of a common prime meridian.  I here take the opportunity of thanking Mr. RUTHERFURD for his courtesy, and I no longer object to proceeding with the debate.

What we ask is, that after the general declaration of the second session as to the utility of a common prime meridian, the Congress should discuss the question of the principle which should guide the choice of that meridian.

Being charged to maintain before you, gentlemen, the principle of the neutrality of the prime meridian, it is evident that if that principle was rejected by the Congress it would be useless for us to take part in the further discussion of the choice of the meridian to be adopted as the point of departure in reckoning longitude.
