Edward Everett, who at that time was president of Harvard College, took a great interest in the matter, and immediately opened a correspondence with the proper authorities, and sent a notice of the discovery to the "Astronomische Nachrichten." The priority of Miss Mitchell's discovery was immediately admitted throughout Europe.

The comet is constantly called 'Miss Mitchell's comet' in the monthly journal of the Royal Astronomical Society at London, and in the 'Astronomische Nachrichten, the well-known astronomical journal, edited by Mr. Schumacher himself, at Altona. "Last winter I addressed a letter to Mr.

This foundation and the conditions on which the medal would be awarded were announced to the public in the "Astronomische Nachrichten" for the 20th of March, 1832. The medal will be given to the first discoverer of any comet, which, at the time of its discovery, is invisible to the naked eye, and whose periodic time is unknown.

It was followed in 1822 by the Astronomische Nachrichten, later by the Memoirs and Monthly Notices of the Astronomical Society, and by the host of varied publications which now, in every civilised country, communicate the discoveries made in astronomy to divers classes of readers, and so incalculably quicken the current of its onward flow. Public favour brings in its train material resources.

Then Piazzi, Lalande, Groombridge, and Bessel were followed by Argelander with his 324,000 stars, Rumker's Paramatta catalogue of the southern hemisphere, and the frequent catalogues of national observatories. Later the Astronomische Gesellschaft started their great catalogue, the combined work of many observatories. Other southern ones were Gould's at Cordova and Stone's at the Cape.

Prompt information, however, of the discovery was transmitted by Mr. Mitchell to his friend, William C. Bond, Esq., director of the observatory at Cambridge. The observations of the Messrs. Bond upon the comet commenced on the 7th of October; and on the 30th were transmitted by me to Mr. Schumacher, for publication in the "Astronomische Nachrichten." It was stated in the memorandum of the Messrs.

Chandler's first list of 225 such objects, published about the same time, received successive expansions in 1893 and 1896, and finally included 400 entries. A new "Catalogue of Variable Stars," still wider in scope, will shortly be issued by the German Astronomische Gesellschaft. Mr.

Frederick VI., King of Denmark, had offered, Dec. 17, 1831, a gold medal of the value of twenty ducats to the first discoverer of a telescopic comet. The regulations, as revised and amended, were republished, in April, 1840, in the "Astronomische Nachrichten." When this comet was discovered, the king who had offered the medal was dead.

The best example of this is the work undertaken in 1870 by the Astronomische Gesellschaft, the great astronomical society of the world. The sky was divided into zones, and astronomers were invited to measure the positions of all the stars in these zones. The observation of two of the northern and two of the southern zones were undertaken by American observatories.

Schmidt shows several low ridges on the N.E. side. In a paper recently published in the Astronomische Nachrichten, Professor W.H. Pickering, describing his observations of the Tycho streaks made at Arequipa, Peru, with a 13 inch achromatic, asserts that they do not radiate from the centre of Tycho, but from a multitude of minute craters on its S.E. or N. rim.
