Kometen. 
hatte der höchstens 10" bis 12" im Durchmesser habende Kern viel 
mehr Licht, als ein Stern zweiter, fast so viel, als ein Stern erster 
Grösse. Es ist zu bedauern, dass keine entscheidende Beobachtung' bei 
diesem höchst merkwürdigen, vielleicht in mehreren hundert Jahren 
sich nicht wieder ereignenden Vorübergange des Kometen vor der 
Sonne unsere Begriffe über den Grad der Durchsichtigkeit der Kometen 
kerne völlig berichtigt hat; aber zweckmässig schien es mir doch zu 
sein, alles, was mir über Beobachtungen der Sonnenscheibe am

[The Quarterly Journal of Science, Literature, and the Arts. Vol. IX. S. 382. London 1820.] 
Bremen, 28 th May 1820. 
The year 1819 will always be memorable in the history of comets. 
It is singular that the small comet discovered by Pons, which appeared 
in June and July in the Lion, describes an ellipsis, and has a very
