nothing, as will appear hereafter.--On Dec. 15th, being on a visit to Dean Peacock at Ely, I examined the Drainage Scoop Wheel at Prickwillow, and made a Report to him by letter, which obtained circulation and was well known.--On May 26th the manuscript of my article, 'Tides and Waves,' for the Encyclopaedia Metropolitana was sent to the printer. I had extensive correspondence, principally on local tides, with Whewell and others. Tides were observed for me by Colby's officers at Southampton, by myself at Christchurch and Poole, at Ipswich by Ransome's man; and a great series of observations of Irish Tides were made on my plan under Colby's direction in June, July and August.--On Sept. 15th Mr Goulburn, Chancellor of the Exchequer, asked my opinion on the utility of Babbage's calculating machine, and the propriety of expending further sums of money on it. I replied, entering fully into the matter, and giving my opinion that it was worthless.--I was elected an Honorary Member of the Institution of Civil Engineers, London. "The reduction and printing of the astronomical observations had been getting into arrear: the last revise of the 1840 observations went to press on May 18th, 1842. On Aug. 18th came into operation a new organization of Assistants' hours of attendance, &c., required for bringing up reductions. I worked hard myself and my example had good effect." His reference to this subject in his Report to the Visitors is as follows: "I have in one of the preceding articles alluded to the backwardness of our reductions. In those which follow it I trust that I have sufficiently explained it. To say nothing of the loss, from ill health, of the services of most efficient assistants, I am certain that the quantity of current work will amply explain any backwardness. Perhaps I may particularly mention that in the observations of 1840 there was an unusual quantity of equatoreal observations, and the reductions attending these occupied a very great time. But, as regards myself, there has been another cause. The reduction of the Ancient Lunar and Planetary Observations, the attention to chronometer constructions, the proposed management of the printing of papers relating to important operations at the Cape of Good Hope; these and similar operations have taken up much of my time. I trust that I am doing well in rendering Greenwich, even more distinctly than it has been heretofore, the place of reference to all the world for the important observations, and results of observations, on which the system of the universe is founded. As regards myself, I have been accustomed, in these matters, to lay aside private considerations; to consider that I am not a mere Superintendent of current observations, but a Trustee for the honour of Greenwich Observatory generally, and for its utility generally to the world; nay, to consider myself not as mere Director of Greenwich Observatory, but (however unworthy personally) as British Astronomer, required
