are well known and higlil}' valued among astronomera. With the 

 Mannheim telescope he observed many nebulte, and published a 

 catalogue of these also. 



Upon the death of Argelander, in 1875, Schonfeld was recalled 

 to Bonn to succeed him. He then undertook the extension of the 

 great catalogue above mentioned into the southern hemisphere, as 

 far as the twenty-third degree of south declination. The number 

 of stars thus added to the catalogue was 133,659. This additional 

 catalogue, as well as that previously prepared under Argelander's 

 direction, is accompanied by an atlas, showing the places of all 

 the stars observed. The value of the entire work to astronomers 

 can hardly be described in terms which would not seem extrava- 

 gant to readers of other professions. 



But the mere enumeration of the official occupations which 

 formed the regular business of Schonfeld's life would give a very 

 imperfect idea of his claim to the esteem and gratitude of his col- 

 leagues and contemporaries. As has already been suggested, his 

 mind was distinguished by its breadth and versatility. An aston- 

 ishing memory, very extensive reading, and pre-eminent ability in 

 teaching and in writing, combined with a perfectly unpretentious 

 and amiable disposition, made him, as may easily be imagined, 

 a leader in his profession, commanding the admiration and good 

 will of all who knew him personally or only by his jiiiblications. 

 He was one of the most active and valuable members of the As- 

 tronomische Gesellschaft, and, as one of its secretaries in 1875 and 

 later, was largely concerned in the publication of its journal, the 

 ** Vierteljahrsschrift," to which he frequently contributed articles 

 of more than ordinary interest. 



He died on May 1, 1891, after a prolonged illness, which, in the 

 opinion of some of his friends, was to be ascribed to the unremit- 

 ting labor to which he subjected himself in the observations for 

 the extension of his great catalogue of stars, after his return to 

 Bonn. His interest in astronomy continued unabated to the last, 

 and the number of the '' Astronomische Nachrichten " subsequent 

 to that in which his death is announced contains a final article 

 from his pen on a point in the history of astronomy, in explaining 

 which his learning and ingenuity are, as usual, made evident.
