ANNIVERSARY ADDRESS OF ^hc ^presibeitt, M r . R. L. J. E l l e r y , F.R.S., F.R.A.S., Government Astronomer. (Delivered to the Members of the Royal Society of Victoria, at their Annual Conversazione, held August 23rd, 1880.) G e n t l e m e n o f t h e R o y a l S o c ie t y , When we last met at a similar gathering to the present, I told you that the council was taking steps to carry out certain alterations within this building, with the view of affording more room, as well as of otherwise improving this part of the house. These alterations, as you may now see, have been completed, and we have, besides this well- proportioned lecture-room, a lai'ge additional room beneath, which adds very considerably and conveniently to the house accommodation. Moreover, the rooms generally have been renovated, and above all the exterior of the building, which has for so long a time presented a somewhat shabby and dilapidated appearance, has been thoroughly repaired, and finished with stucco in a plain and substantial style. I am glad to tell you that although this undertaking has trenched heavily on our exchequer, and will hypothecate a part of our next year’s income, it will not leave us in any serious debt. The Society entered on its twenty-third season in March, last, and it gives me pleasure to inform you that it is pro xii President’s Address gressing steadily, and getting gradually stronger from year to year, not only in numbers, but in the acquisition of new and energetic working members, who have taken up investi gation and research in some of the various by-ways of know ledge which fall within its scope. Our ordinary meetings have, on the whole, been better attended during the last year than heretofore, and there has been no lack of new and interesting matter to occupy attention and excite discussion on each occasion. Our printed transactions, now so promptly placed in the hands of our members, give the best evidence of the Society’s vitality. Some of the sections for which our rules provide have been formed, and have held their meeting regularly each month; Section A, which embraces mathematics, astronomy, physical geography, and engineering, has, I think, been the busiest one. Another section, combining the subjects classified in our rules under sections, B, C, and D—viz., chemistry, mineralogy, natural history, geology, and microscopy—has also been formed, and commenced its meetings some few months ago. The new rule enabling the Society to admit associates at a smaller subscription than members, and to which I referred in my last address, has continued to work very satisfactorily, and we have now no less than twenty-five who have entered the Society under this rule. We con tinue to increase our friendly relations with kindred societies abroad, by interchange of transactions and publi cations and in other ways; and, of course, our valuable and, as far as Australia is concerned, somewhat unique library grows in proportion. In October last the council made a change with regard to the paid assistants of the Society. The hallkeeper was relieved of all clerical work, and the services of an assistant-secretary and librarian were obtained, and the result so far is that the house and grounds are kept in much better order, and the library and clerical duties are more methodically and satisfactorily performed than under the former arrangements. I think I have now for the year 1880. xiii referred to all the principal facts in connection with the past year’s domestic history of the Society, and I propose now to crave your patience for a few minutes while,.in accordance with my usual custom on these occasions, I briefly review the year’s work of our national art and science institutions. While our Observatory, over which I have the honour to preside, has been fully occupied with its usual continuous work, but few matters of more than ordinary interest have occurred to claim its special attention since my last address. The comet of February broke the monotony of the routine work, but the hazy horizon so prevalent during the evenings of that month completely hindered satisfactory observation in the early part of its apparition, when it set soon after the sun; and afterwards, when measurements could be made, it increased its distance from us so rapidly that only a very incomplete series of measures could be secured. As there is rather more interest than usual attaching to this comet, I shall refer to it again presently. In anticipation of the next'Transit of Venus in 1882, the Astronomer Royal, Sir George Airy, has brought promin ently under the notice of the scientific world in the old country the great desirability of determining telegraphically the longitude of Melbourne, or some one of the Australian cities connected with it by telegraph. I am now in com munication with the president of the Royal Society in London on the subject. I am also in correspondence with the hydrographic office at Washington on the same matter, for the Americans propose to connect J&pah, China, and probably Australia, with America by a chain of telegraphic determi nations of longitude. It is, therefore, quite probable that before very long the longitude of our Observatoryfrom Green- which will be determined by the most accurate method we know of—namely, by the interchange of telegraphic signals.
