Bessel has several times repeated this statement to myself among other people varying the details as the narrator of real experiences always does, but never by any chance contradicting himself in any particular. And the statement he makes is in substance as follows. In order to understand it clearly it is necessary to go back to his experiments with Mr. Vincey before his remarkable attack. Mr.
Thus astronomy became a truly universal science; uncertainties and disparities were banished, and observations made at all times and places rendered mutually comparable. More, however, yet remained to be done. In order to verify with greater strictness the results drawn from the Bradley and Piazzi catalogues, a third term of comparison was wanted, and this Bessel undertook to supply.
Vincey's story, he gave himself at once with great energy to the pursuit of this clue to the discovery of Mr. Bessel. It would serve no useful purpose here to describe the inquiries of Mr. Vincey and himself; suffice it that the clue was a genuine one, and that Mr. Bessel was actually discovered by its aid.
But something more was needed than the diligence of individual observers. A systematic reform was called for; and it was this which Bessel undertook and carried through. Direct observation furnishes only what has been called the "raw material" of the positions of the heavenly bodies.
But the thought that the seance was almost over only made Mr. Bessel the more earnest, and he struggled so stoutly with his will against the others that presently he gained the woman's brain. And then the other shadows and the cloud of evil spirits about him had thrust Mr. Bessel away from her, and for all the rest of the seance he could regain her no more.
In 1838 Bessel announced from the Konigsberg observatory that he had succeeded, after months of effort, in detecting and measuring the parallax of a star. Similar claims had been made often enough before, always to prove fallacious when put to further test; but this time the announcement carried the authority of one of the greatest astronomers of the age, and scepticism was silenced.
In the chapter on meteorology we shall see how the solution of this mystery that puzzled Halley and his associates all their lives was finally attained. Halley was succeeded as astronomer royal by a man whose useful additions to the science were not to be recognized or appreciated fully until brought to light by the Prussian astronomer Bessel early in the nineteenth century. This was Dr.
And clustering also about him, as they clustered ever about all that lives and breathes, was another multitude of these vain voiceless shadows, longing, desiring, seeking some loophole into life. For a space Mr. Bessel sought ineffectually to attract his friend's attention. He tried to get in front of his eyes, to move the objects in his room, to touch him. But Mr.
The nineteenth century was well on its way before the instruments of the astronomer were brought to such perfection as to admit of the measurement. From the time of Copernicus to that of Bessel many attempts had been made to measure the parallax of the stars, and more than once had some eager astronomer thought himself successful.
He knew at once that it was Mr. Bessel. But it was Mr. Bessel transfigured. He was hatless and dishevelled, his collar was torn open, he grasped a bone-handled walking-cane near the ferrule end, and his mouth was pulled awry. And he ran, with agile strides, very rapidly. Their encounter was the affair of an instant. "Bessel!" cried Vincey. The running man gave no sign of recognition either of Mr.
