We have to correct our observations for such errors, that is to say, we have to determine the errors in the positions of our telescopes and the errors in the going of our clocks, and then we have to determine what the observations would have been had our telescopes been absolutely perfect, and had our clocks been absolutely correct. There are also many other matters which have to be attended to in order to reduce our observations so as to obtain from the figures as yielded to the observer at the telescope the actual quantities which it is his object to determine.英文原著 · 《Great Astronomers》
If the medical theorist insists on being consulted, and we see fit to indulge him, he cannot be allowed to assume that the alleged laws of contagion, deduced from observation in other diseases, shall be cited to disprove the alleged laws deduced from observation in this. Science would never make progress under such conditions. Neither the long incubation of hydrophobia, nor the protecting power of vaccination, would ever have been admitted, if the results of observation in these affections had been rejected as contradictory to the previously ascertained laws of contagion.英文原著 · 《Medical Essays》

The building of the Cambridge Astronomical Observatory was completed in 1824, but in 1828, when Airy entered on the discharge of his duties as Director, the establishment was still far from completion, in so far as its organisation was concerned. Airy commenced his work so energetically that in the next year after his appointment he was able to publish the first volume of "Cambridge Astronomical Observations," notwithstanding that every part of the work, from the making of observations to the revising of the proof-sheets, had to be done by himself.英文原著 · 《Great Astronomers》
For God's sake, revolve all these things seriously in your thoughts, before you launch out alone into the ocean of Paris. Recollect the observations that you have yourself made upon mankind, compare and connect them with my instructions, and then act systematically and consequentially from them; not 'au jour la journee'. Lay your little plan now, which you will hereafter extend and improve by your own observations, and by the advice of those who can never mean to mislead you; I mean Mr. Harte and myself.英文原著 · 《Letters to His Son, 1750》
