  Dear Sir,
  A short time since I learnt that Mr. Dent, Chronometer-maker, of London, was likely to go to Paris, and I intrusted to him the diploma of the R. Astronomical Society notifying your election as a Foreign Associate of that Society. I trust that you have safely received that paper. I have not seen Mr. Dent since his return, but I have heard that he saw you in Paris. And the reporter brought to me two pieces of information which were entirely new to me.
  The first is, that you are a married man and that Madame Le Verrier is likely to accompany you on any journey which you may make shortly. Mrs Airy and myself beg that you will present our compliments to Madame Le Verrier, and that you will say to her that we anxiously hope that she as well as you will commence your acquaintance with England by passing some time in our house. This will be very agreeable to us : and to Madame Le Verrier we are sure, it will be found the most pleasant way of entering into the customs of a strange country.
  The next information was, that you were partly unwilling to come to England because you heard that, in the late discussion about the new planet, a national feeling or a feeling of personal hostility towards yourself may have entered, which would make your residence in England unpleasant. If this is your fear, I assure you that you may entirely lay it aside. I verily believe that there is not one person in England who entertains such a feeling, and I am sure that those who have entered most warmly into the different discussions have but one feeling of most profound respect and admiration towards you. The discussions in the R. Astronomical Society have turned entirely upon points of business regarding the extent to which the Society ought to alter the terms of its original constitutions, which have failed entirely to meet the necessities of this extraordinary case.
  I understood from you that you were likely to visit England in June, probably to attend the meeting of the British Association (at which, as Colonel Sabine informed me, you were expected). In that case, I would suggest that you should come to Greenwich some time earlier, probably before the end of May, and at any rate before the first Saturday of June (when the annual visitation of the R. Observatory takes place). If you will give me notice of the route which you take, I will give you instructions as to the best way of coming to Greenwich.
  I am, my dear Sir,
  Faithfully yours
  G. Airy »
