This expedition was one of those organised by the Joint Permanent Eclipse Committee of the Royal Society and the Royal Astronomical Society, funds being provided from a grant made by the Government Grant Committee. The following were the principal objects which I had in view in arranging the expedition:— To obtain a long series of photographs of the chromosphere and flash spectrum, including regions of the sun’s surface in mid-latitudes, and near one of the poles.

In the Fourteenth Volume of the Transactions of the Royal Astronomical Society will be found a full account of the Cavendish apparatus, and of the mode of experimenting followed by Mr. Baily. It will therefore not be necessary for me, in this place, to enter into any detail as to the different parts of the instrument, and the various precautions adopted in order to avoid that singular source of error 'currents of air in the torsion box arising from unequal temperature,’ which had been discovered by Cavendish. It will be sufficient for me to state that all the arrangements are of a highly satisfactory kind, and that I am of opinion that no aerial currents could have existed in the torsion box. The deduction of the mean density of the earth from the observed vibrations of the balls influenced by the torsion force and the attraction of the masses, is founded on a mathematical theory of the motion of the balls given by the Astronomer Royal, Mr. Airy ; and as this theory is certainly insufficient to account for the discrepancies, it will here be necessary to give a brief sketch of it.

My Lord Chancellor, Mr. Vice-Chancellor, Dr. Campbell, Ladies and Gentlemen: It would be an impertinence on my part to try to add anything to the Cambridge welcome which the Chancellor has offered you, but it is my privilege to be allowed to offer you a few words of welcome from a somewhat different angle. As the Chancellor has said, it is my good fortune to be officially connected with the two learned societies to whom, I suppose, your visit to this country means most: the Royal Society, which takes all natural knowledge for its province, and which is especially interested in international co-operation in the pursuit of such knowledge, and the Royal Astronomical Society, which takes astronomical knowledge for its special care. I am sure that both these bodies would wish that I should seize this opportunity to offer a most cordial welcome to our astronomical visitors from other countries; a welcome not only to Cambridge, but to this country in general. We feel it right that your visit should begin at Cambridge, but we are sure it is not right that it should end there; we hope you will remember that, after Cambridge, London also exists.
