Excerpt from The Astronomical Register, Vol. 20: A Medium of Communication for Amateur Observers, and All Others Interested in the Science of Astronomy; Nos. 229 to 240, January to December, 1882
Mr. N eison: As regards the diameters, our paper rests upon investigations made by myself seven years ago. Mr. Stone has gone over the observations and cannot get the same figure. I did not like to say I was not wrong, because it is seven years ago since I did the work, and I might possibly have made an error; but since that time I have gone over, all the observations again and have got exactly the same results as I did before. I can find no possible room for mistake. My results agree, however, with those of Sir George Airy, in his introduction to the Greenwich observations; and his results are obtained almost in the same way as mine. Therefore it seems that some independent observer should go over the calculations too, and I hepe that Professor Newcomb is going to do so. In regard to that part of Mr. Stone's paper in which he speaks of applying some corrections for dia meters, there is here something extraordinary which I cannot understand, because the results are diametrically opposed to mine. I took Sir George Airy's figures unaltered, and assumed them to be correct. But here, again, I think Professor N eweomb is coming to our assistance and will give the Society his results on this particular point. Then the Society will have three views before it, and will see on which side the majority lies.
Mr. Stone: When Mr. N eison says his results agree with those of the astronomer-royal, I think he is under a misapprehension, because the results given by the astronomer-royal are for the vertical diameters.
Mr. Neison: I was referring to the statement of Sir George Airy in the volume for 1856.
