XLIX. An Account of the Barometer, and the State of the Weather, at Dublin, from the 7 of March 1752, to the 28 of February 1753, by James Simon, Esquire, F. R. S. and Secretary of the Incorporated Society at Dublin: Communicated by Mr. Henry Baker, F. R. S. Dear Sir, Dublin, Sept. 4, 1753. I NOW send you my journal of the weather for the last year, from the 7 of March, 1752, to the 28 of February, 1753. You will, perhaps, find it too minute; but whatever fault you find in it shall be rectified for the future, if you are so kind as to let me know, how I should proceed to render it useful. Deal with me as a friend; inform me of my mistakes; and if you do not think it deserves to be laid before the Royal Society, I beg you will not let it be seen; if otherwise, you have my leave to lay it before them. My chief ambition would be to deserve their approbation and esteem: of this you may assure them, and of my sincere respect and regard. I have observed, that the friction is so great in the common barometer, by the smallness of the tube, that I wrote to London for a larger tube. It is something more than one quarter of an inch clear in the bore; and it took me two pounds and a quarter of clean purified mercury to fill it. The cistern, which receives the mercury, is pretty large, with a wide mouth; and is cover'd with a silk gauze, besides the usual My Barometer was finished the 6th of March. The Tube is a quarter of an inch clear in the bore, and took two pounds and a quarter of clean mercury to fill it. | April | Morning | Noon | Evening | |-------|---------|------|---------| | 1 | Fr |
